As shown in fig. 1, the embodiment of the invention provides an alarm auxiliary decision-making method of a centralized control center monitoring system of a river basin step power plant, which is used for analyzing alarm signals sent out in the process of monitoring a step power plant managed by the step power plant centralized control center and providing an alarm processing flow for staff to refer to, so as to assist staff to make decisions and process alarms after the monitoring system sends out alarms.
Referring to fig. 1, the method for alarming auxiliary decision-making of the centralized control center monitoring system of the river basin step power plant provided by the embodiment comprises the following steps:
s1, establishing a historical database, a decision database and a storage database, wherein the historical database stores historical data of all power generation equipment of the step power plant, and the decision database stores a typical alarm decision model;
s2, acquiring alarm information from a centralized control center monitoring system of the river basin step power plant, and storing the alarm information and operation information of power generation equipment related to the alarm information into a storage database;

s6, recording the alarm processing decision set forth in the step S4 and the alarm processing flow formed in the step S5 to form an alarm event report, and storing the alarm event report into a storage database.
The method for alarming auxiliary decision making of the centralized control center monitoring system of the river basin step power plant, provided by the embodiment, comprises the following working processes: firstly, establishing a historical database, a decision database and a storage database, wherein the historical database stores historical data of all power generation equipment of a step power plant, the historical data comprises historical operation data information, historical fault information and other information with reference function on alarm processing of each power generation equipment, the decision database stores a typical alarm decision model, and the alarm decision model comprises alarm information, operation state and operation parameter information of the power generation equipment related to the alarm, historical data information of the power generation equipment related to the alarm, processing advice of the alarm and other contents; after the monitoring system gives an alarm, the alarm information is acquired, the alarm information and the operation information of the power generation equipment related to the alarm information are stored in a storage database to determine equipment generating faults, historical data of the related power generation equipment in the historical database and an alarm decision model corresponding to the alarm information in a decision database are called according to the acquired alarm information and the determined fault equipment, an alarm auxiliary decision process is started after enough reference materials are called, the proposed alarm decision is displayed on a display device for a worker to read, and an alarm processing process is further formed according to the content stored in the proposed alarm decision model and is displayed on the display device for the worker to refer to, so that the worker is assisted in making decisions and processing processes for the alarm while prompting the alarm, the worker is prevented from missing, the alarm processing efficiency of the worker is improved, and after the alarm processing is finished, the alarm processing decision and the alarm processing process form an alarm event report and are stored in the storage database, so that the worker can conveniently review the alarm event report.
In this embodiment, step S2 further includes identifying and classifying the alarm information obtained from the centralized control center monitoring system of the river basin step power plant, determining whether the level of the alarm information affects the operation of the power generation device, and if the level of the alarm information affects the operation of the power generation device, performing step S3; if the level of the alarm information does not affect the operation of the power generation equipment, the alarm information is stored in a storage database and the step S3 is stopped. Because the step power plant generator set is in normal operation, part of the alarms in the monitoring system belong to the alarms in the normal operation event, the normal operation of the generator set is not affected, part of the alarms do not affect the normal operation of the generator set immediately after the occurrence of the alarms, but the monitoring needs to be enhanced, the checking processing is immediately carried out after the disconnection and the stop of the generator set, and part of the alarms need to be checked immediately by staff, and relevant safety measures are taken, therefore, the level of the alarm information is identified before the auxiliary decision making work is carried out, the interference of low-level alarms on the alarm auxiliary decision making process can be reduced, and the probability that the staff neglects important alarms is further reduced.
Specifically, step S2 further includes filtering alarm information obtained from the centralized control center monitoring system of the river basin step power plant. Because the centralized control center monitoring system of the step power plant in the decision-making basin monitors the running condition of all power generation equipment in the step power plant, and performs dispatching operation management work on the power generation unit of the step power plant, the quantity of alarm data generated by the monitoring system every day is large, the alarm auxiliary decision-making process is directly performed, the alarm auxiliary decision-making workload is large, the staff on duty is not beneficial to alarm processing work, and cannot develop other dispatching operation management work in time, therefore, the monitoring system firstly recognizes the alarm when the alarm occurs, the conventional alarm without influencing the power generation equipment is directly filtered, the alarm auxiliary decision-making process is not performed, and the alarm auxiliary decision-making process is performed when the alarm influencing the safe and stable operation of the power generation equipment is performed.
In detail, at present, the alarm in the monitoring system mainly comprises a switching value alarm and an analog quantity out-of-limit alarm, wherein the switching value alarm is a change condition of the state of the power generation equipment, namely, the state of the power generation equipment in the monitoring system is changed between operation and disconnection, the analog quantity out-of-limit alarm is a change condition of related numerical values of the power generation equipment, when the numerical value of the analog quantity is larger than an alarm fixed value, the monitoring system triggers the alarm, and after the switching value of the monitoring system alarms, the state of the power generation equipment is changed, namely, the state of the power generation equipment is changed from disconnection to operation or from operation to disconnection, the monitoring system sets the switching value alarm as a normal event message when the switching value alarm is reset, and whether the alarm is reset or not needs to be mastered when an alarm auxiliary decision process is executed, so that all data need to be fetched when the operation information of the power generation equipment is called. When the monitoring system sends out the switching value alarm, the alarm auxiliary decision process needs to be started in time, the reason and the influence generated by the alarm are analyzed, when the monitoring system sends out the analog value alarm, the monitoring of related power generation equipment needs to be enhanced when the operation parameters exceed the minimum limit, the power generation equipment can continue to operate at the moment, and the risk of stopping the power generation unit is generated when the operation parameters exceed the maximum limit, so that the alarm auxiliary decision process needs to be started in time.
In this embodiment, step S2 further includes identifying the alarm information obtained from the centralized control center monitoring system of the step power plant in the river basin, and determining whether the number of times of generating the alarm information with the same content in the preset first time interval is greater than or equal to two, if so, performing step S3 only on the alarm information generated for the first time; if the number of the alarm messages is less than twice, step S3 is carried out on the alarm messages. The alarm jitter phenomenon can occur in the operation process of the monitoring system, namely the same alarm is continuously repeated in a short time, and the alarm decision system can make a decision every time the monitoring system makes an alarm, so that the alarm jitter of the monitoring system can have adverse effects on the auxiliary alarm decision process, not only occupies a large amount of operation resources, but also affects the monitoring and processing of the alarm by staff. Therefore, by setting the first time interval, the alarm jitter is judged when the alarm information of the same content appears twice or more in the first time interval, and the alarm auxiliary decision process is only carried out on the alarm appearing for the first time at the moment, and meanwhile, the alarm jitter phenomenon is prompted to appear for the staff, so that the influence of the repeated auxiliary decision of the same content on the staff to judge is avoided.
Specifically, step S2 further includes identifying the alarm information obtained from the centralized control center monitoring system of the river basin step power plant, and determining whether the number of times of generating the alarm information with the same content in a preset second time interval is greater than or equal to two times, where the second time interval is greater than or equal to the first time interval, and if so, pushing an alarm processing decision and an alarm processing flow corresponding to the alarm information generated for the first time to the display device; if the number of the alarm messages is less than twice, step S3 is carried out on the alarm messages. In the process of carrying out the auxiliary decision-making of the alarm, after a first time interval and when the alarm information with the same content appears again within the limit of a second time interval, the alarm processing decision and the alarm processing flow corresponding to the alarm information generated for the first time are pushed to the display equipment and prompt the staff to carry out the same alarm, so that the auxiliary decision-making flow of the alarm can be omitted, the processing efficiency of the auxiliary decision-making flow of the alarm can be improved, and when the alarm information with the same content appears again after the limit of the second time interval is exceeded, the alarm information is considered to be an alarm newly appearing by the monitoring system, and the auxiliary decision-making flow of the alarm is carried out again.
In the embodiment, in step S1, the history data is stored in a history database in the form of text, and the alarm decision model is stored in a decision database in the form of text; and step S3, performing word recognition on the message of the alarm information, and searching related contents in the history database and the decision database respectively. When the alarm auxiliary decision process is executed, a large amount of reference data is needed to be used as decision basis, and because the types and the quantity of data stored in the historical database and the decision database are complex, effective data are needed to be selected to be used as data for the alarm auxiliary decision when the alarm auxiliary decision process is executed, the influence of useless data on the accuracy of the alarm auxiliary decision is reduced, the required data are respectively stored in the historical database and the decision database in a text form, the corresponding text data are called from the historical database and the decision database when the alarm auxiliary decision process is executed, the text recognition is carried out on the message of the alarm information, the keyword is selected, the required data can be quickly obtained by respectively searching the content related to the message keyword of the alarm information in the historical database and the decision database, the alarm auxiliary decision efficiency is improved, and the interference of useless information is reduced.
Optionally, the history database is also stored with a work record of the central control center for dispatching and operating on duty, the decision database is also stored with data such as a power generation equipment operation and maintenance report, a power generation equipment maintenance report, a power generation set test report and a power generation set maintenance report, the data are uploaded in a text form, the report recorded in a chart form is named by the text and then uploaded, and when the report is required to be called, the report is respectively searched in the history database and the decision database or the characters in the chart are identified, so that sufficient data can be obtained when the alarm auxiliary decision process is executed.
In this embodiment, step S3 further includes analyzing operation information of the power generation device related to the alarm information, determining whether other devices related to the power generation device will trigger the alarm information, if yes, retrieving historical data of other devices related to the historical database and an alarm decision model corresponding to the alarm information in the decision database, and performing step S4; if not, step S4 is immediately performed. During the operation of the power generation equipment, the faults of part of the power generation equipment may cause the faults of other equipment related to the power generation equipment, or the faults of related other equipment cause the abnormal oil pressure alarm of a speed regulator system, for example, the fault alarm of a speed regulator oil pump may cause the abnormal oil pressure alarm of the speed regulator system, so that when an alarm auxiliary decision process is carried out, the other equipment related to the alarm power generation equipment needs to be comprehensively analyzed to determine whether the related equipment needs to be analyzed, and if the related equipment needs to be analyzed, the operation data of the alarm power generation equipment and the operation data of the other equipment related to the alarm equipment are simultaneously called to improve the reliability of the alarm auxiliary decision.
In detail, the data fetched from the monitoring system by the alarm auxiliary decision process mainly comprises analog quantity data and switching value data, and the data mainly comprise equipment operation parameters, operation states and the like. The analog quantity data which are called from the monitoring system are displayed in a digital mode, for example, an alarm generated when the voltage of the generator set end exceeds the limit is analog quantity data, and the voltage of the generator set end is recorded in the monitoring system in a digital mode at the moment, so that the analog quantity of the monitoring system is called, namely, the number corresponding to the time for generating the alarm is called, the time can be taken as a horizontal axis after a large amount of analog quantity data are called, the size of the number is taken as a vertical axis to form an operation parameter curve, namely, the operation parameter condition of the power generation equipment is formed by acquiring historical analog quantity data, and the operation parameter curve of the power generation equipment has guiding significance for the prediction of the operation state and the later operation condition of the power generation equipment. The switching value data fetched from the monitoring system is mainly the change of the operation state of the generating equipment, for example, the outlet breaker of the generating set is separated, i.e. the outlet breaker of the generating set is changed from the operation state to the disconnection state, the state of the generating equipment is displayed as the change of the operation and the disconnection in the monitoring system, and the state of part of important generating equipment can influence the alarm decision, so that the states of other equipment related to the generating equipment for generating the alarm also need to be fetched when the alarm auxiliary decision process is executed.
In this embodiment, the analog data is information such as an operation parameter of the power generation device, and when the current operation state of the power generation device can be analyzed according to the condition of the operation parameter, the value of the analog data can be directly compared with the upper limit value and the lower limit value of the operation parameter to determine whether the operation parameter is out of limit, or the operation parameter is formed into a parameter curve and the change trend of the middle-term analog data is checked, or the analog data is combined with the switching value data of the power generation device related to the analog, if the analog data of the power generation device is abnormal and the switching value data acts, the device is proved to be determined to be a fault, and if the analog is normal and the switching value data is abnormal and the switching value data is normal, the state of the power generation device needs to be determined after continuous analysis and alarm. The switching value data mainly indicates the data deflection of the power generation equipment, the switching value data is mainly used for analyzing the current state of the power generation equipment when the alarm auxiliary decision process is executed, and whether the power generation equipment is in an abnormal state or not can be judged according to the switching value data of the power generation equipment, so that the alarm power generation equipment can be conveniently and continuously analyzed for other related information.
In the embodiment, in step S1, an alarm decision model in a decision database is divided into a general alarm decision model and an important alarm model according to the emergency degree of an alarm; step S3 also comprises the steps of carrying out emergency grade classification on the alarm according to the influence degree of the alarm on the power generation equipment, the difficulty degree of alarm processing and other conditions on the alarm information obtained in the step S2, and calling a general alarm decision model from a decision database when the alarm grade of the alarm information is low; when the alarm level of the alarm information is high, an important alarm decision model is called from the decision database. Because the centralized control center of the river basin step power plant needs to monitor the operation conditions of all power generation equipment of the step power plant, the generated alarm quantity is huge, part of the alarms of the monitoring system can influence the operation of the generator set, and the part of the alarms can not influence the operation of the generator set, so that the emergency treatment degree of the alarms is different, a plurality of different alarm decision models are stored in a decision database in advance for executing an alarm auxiliary decision process, so that the corresponding alarm decision models are used for coping with different alarms, the alarm decision models are divided into a general alarm decision model and an important alarm decision model according to the emergency degree of the alarms, the monitoring system distinguishes the conditions of the influence degree of the alarm information on the power generation equipment, the difficulty degree of the alarm treatment and the like according to the alarm auxiliary decision process, and the data are selected for analysis treatment according to the alarm auxiliary decision process after the alarm decision model to be adopted is determined.
In this embodiment, in step S5, the alarm processing flow includes several independent alarm processing steps, each of which corresponds to an alarm processing action, respectively; and step S5, selecting the alarm processing steps according to the alarm processing decision provided in the step S4, and forming an alarm processing flow by the selected alarm processing steps in sequence. After the monitoring system gives an alarm and puts forward an alarm processing decision flow, the alarm processing flow can be built according to the alarm processing decision, the alarm processing steps comprise prompting staff to confirm the alarm, confirming whether the alarm is returned or not, calling information such as relevant operation parameters of alarm equipment, and the like, carrying out alarm decision, informing relevant staff to process according to decision content, monitoring a processing process, evaluating after decision processing, starting alarm processing safety measures, enabling the alarm to have little influence on the power generation equipment, stopping operation immediately after serious faults of the power generation equipment, calling historical faults and defect information of the relevant equipment of the alarm, and the like.
Specifically, after the alarm processing flow is built, the alarm processing flow needs to be reasonably checked to check whether the sequence of alarm processing steps of the alarm processing flow is reasonable, if the alarm processing flow does not pass the check, a prompt is sent to prompt a worker to check, the alarm processing flow is built again, if the alarm processing flow passes the check, the alarm processing flow is displayed on a display device for the worker to refer to, and the worker can add or delete the alarm processing steps by himself through an input device to adapt to the actual working requirement of the worker.
In this embodiment, step S51 is further included after step S5, after the execution of the alarm processing procedure is completed, the operation state and the operation parameter of the power generation device that generates the alarm information are obtained through the monitoring system, and the current operation state and the operation parameter of the power generation device are compared with the operation state and the operation parameter of the power generation device when the monitoring system generates the alarm. The alarm processing flow established by the method for assisting decision making by the monitoring system of the centralized control center of the river basin step power plant can be automatically executed by the system of the centralized control center, or the staff refers to the alarm processing flow of the assembly and combines the experience of the staff to carry out manual processing, after the monitoring system alarms, the comparison analysis is needed to be carried out on the operation condition of the generating equipment before and after the alarm processing to judge whether the alarm processing is perfect, so as to confirm whether the generating set can continue to stably operate, and if the operation state of the generating set after the processing is unstable, a stop application is needed to be timely provided in the process of the alarm processing or after the processing is finished, so that the unplanned shutdown of the generating set is avoided.
In detail, after the alarm processing flow is executed, the centralized control center system can judge that the alarm processing is finished according to no operation of the monitoring system or no change of the state of the power generation equipment, or the manual setting processing of the staff is finished, and after the alarm processing of the monitoring system is finished, the monitoring system continuously monitors the operation state and the operation parameters of the power generation equipment generating the alarm, the operation condition of a power generation unit associated with the power generation equipment, whether other alarms exist in the power generation equipment, and the like. And after the alarm processing is finished, the staff is used for retrieving the running state and running data of the generating equipment generating the alarm, the grid-connected running condition of the generating set related to the generating equipment and other data, and comprehensively analyzing and evaluating the alarm processing decision, the alarm processing flow and the alarm processing result of the alarm to be used as support data for optimizing an alarm decision model.
In this embodiment, step S7 further includes sorting the alarm event reports in the storage database after step S6, and transferring the corresponding contents of the sorted alarm event reports to the history database and the decision database. In order to ensure the integrity of the alarm event of the monitoring system, the alarm information and the message information of the invoked monitoring system are required to be combed to form the whole alarm process of the monitoring system, namely, the alarm information related to the alarm is extracted from the beginning of the alarm of the monitoring system until the alarm is reset or processed, and the alarm information and the message are included, therefore, the alarm event report mainly comprises the alarm information, the running state of the alarm missile equipment, the running parameters of the alarm power generation equipment, other equipment conditions related to the alarm power generation equipment, the alarm processing advice and flow, the alarm processing measures, the alarm processing results, the alarm processing evaluation conditions and the like, the alarm event report is formed by automatically extracting related information according to a preset report template and filling the related information into corresponding positions for programming, the report template can be modified and perfected in a man-machine interaction device, a log is formed after each template modification or perfection, the modification time, personnel and modification content are recorded in detail, the report mode of the last version is stored, the finished alarm event report is stored in a database, workers can review in a man-machine interaction device, after a certain time, the alarm event report is automatically decided and is transferred to the database and cleared, and the database is stored in the database.
Preferably, in order to make the decision of the alarm auxiliary decision process more accurate and perfect, the generated alarm processing decision and alarm processing process are required to be analyzed, and the alarm decision model is continuously optimized according to the evaluation conditions of the alarm processing decision and the alarm processing process so as to improve the accuracy of the alarm decision. After the monitoring system gives an alarm, the operator takes the operation parameters and related information of the power generation equipment associated with the alarm to reflect the operation condition of the equipment after making a decision through the alarm auxiliary decision-making process and completing alarm processing according to the alarm processing decision-making process, and evaluates the alarm processing decision-making process and the alarm processing process through the operation condition.
