Technical Field
The invention relates to the technical field of electric power system alarm methods, in particular to a processing method for analyzing and dealing with abnormal alarm of an electric power dispatching informatization system.
Background
Currently, when a user is switched or a monitoring system is maintained, the system can generate relevant operation information by itself. The operation information occupies about half of the rate of the non-important alarm information, and the alarm information can only be used as a data base for carrying out the full development of the post analysis work, so that an operator does not need to immediately process the operation information and the operation information does not need to be displayed in a time sequence alarm window in real time. In addition, the information of the notification types such as the relay protection switching-on/off information, the power system running state information and the like also accounts for a large proportion, and the warning information is usually beneficial to the judgment of field conditions by maintenance personnel.
In the actual operation process of the power system, various external factors generally influence the power system, and a problem of false alarm is generated in a short time. For example, an unstable phenomenon easily occurs in the actual operation process of the power system, so that a sudden change phenomenon occurs in related values such as voltage and current. Normally, such an alarm message will automatically return to the normal position within 3 minutes, but if the alarm message has not disappeared within a short time, it is proved that the problem is indeed present in the field, and it is ensured that the message can be transmitted to the alarm window with a delay.
At present, the processing of the system alarm information by the power dispatching system is to push the alarm information of all systems in real time, and then a watchman needs to find the system alarm information to be processed in the face of tens of thousands of system alarm information pushed in a short time, and performs corresponding response operation on the system alarm information according to the information content. When the processing mode faces massive alarm information, the processing speed is very low, and important system alarm information is easy to miss.

s3: the method comprises the steps that a person on duty correspondingly processes alarm information transmitted to a database by an OCS (online charging system), if the person on duty finds that the alarm is only false alarm information after the person on duty passes through the inspection of a monitoring system, the person on duty artificially ends alarm prompt information, and a processing result is generated into a log;
s4: the database makes a decision on the processed alarm information through the automatic operation and maintenance auxiliary system, the automatic operation and maintenance auxiliary system performs a self-checking action on the alarm data in the automatic operation and maintenance auxiliary system once a period of time passes, if the problem aiming at the alarm is found to be automatically recovered, the OCS system alarms to close the alarm of the database system, the WEB browser in the database automatically initiates a closed-loop operation, and the suspension operation of the alarm is finished;
s5: the database is pushed to a system operator and a system administrator through classification and logic processing, and the OCS system alarms and realizes priority processing of important information with high priority by comparing the application name, the node name and the task content of the alarm information;
as a further description of the above technical solution:
the automatic operation and maintenance auxiliary system comprises an automatic maintenance closed-loop management module, and the automatic maintenance closed-loop management module can enable the WEB browser to automatically initiate closed-loop operation when the OCS system gives an alarm to close the database system.
As a further description of the above technical solution:
the database is provided with a keyword priority mapping table, and the priority mapping table structure comprises numbers and keywords.
As a further description of the above technical solution:
the database realizes priority processing of important information with high priority: the unimportant alarm information is only accumulated with alarm prompt times and cannot be pushed to the operator on duty at the front end, and different alarm information is improved with corresponding priority and pushed to the operator on duty.
As a further description of the above technical solution:
the processing results in the S3 are all displayed in independent pages in an alarm window of the monitoring system, so that a dispatcher is reminded of processing the abnormity in time and assisting in online decision making; meanwhile, the processing result is stored as historical information and is used as the original data of the correlation analysis reasoning inversion; meanwhile, the reasoning process is recorded, and an analysis report is generated and stored in a file form and uploaded to a database so as to be called out for later use.
As a further description of the above technical solution:
the OCS system alarm has a hierarchical model, and the real-time library comprises a primary model, a secondary model and an intermediate result of correlation analysis of the power grid.

1. the invention is provided with an automatic suspension function of system alarm information, which is mainly an automatic classification suspension function developed aiming at a large amount of repeated system alarm information every day. The system can generate a large amount of repeated redundant system alarm information every day, the system classifies the same alarm information by comparing the application name, the node name and the task content, and only accumulates the alarm prompting times for unimportant alarm information without pushing the alarm prompting times to the operator on duty at the front end so as not to bring trouble to the operator on duty.
2. The automatic inspection and check closed-loop treatment function of the system alarm is arranged, the automatic inspection and check closed-loop treatment is mainly that an automatic treatment function system developed for an operator on duty facing mass system alarm data every day carries out self-detection action on the alarm data once a period of time, if the problem aiming at the alarm is found to be automatically recovered, the system automatically initiates closed-loop operation, finishes the suspension operation of the alarm, and automatically carries out closed-loop treatment operation on the recovered alarm information through self-detection of fixed time.
3. The invention can realize manual closed-loop treatment and recording of system alarm information, the power system is influenced by various external elements in the actual operation process, an error alarm is generated in a short time, if the alarm information is not treated by an operator on duty, the system can always execute suspension operation, and the operator on duty can be regularly reminded to deal with the problems. However, if the operator on duty finds that the alarms are actually only false alarm information after checking, the operator on duty is required to manually end the alarm prompt information, and the operation time and the operation record of the operator on duty are strictly controlled, so that accident tracing and problem tracing are facilitated.
