Meanwhile, due to the fact that a large amount of work is overstocked, sequencing processing cannot be conducted according to the degree of the events, important events and work are easily omitted during the shift, and scheduling work cannot be done.

The existing working mode has the following problems:

1. all working problems need to be communicated between the step power plant centralized control center and the step power plant dispatching operation duty personnel in a telephone communication mode, the communication effect is good when a single working problem or a simple working problem is processed, however, when an emergency or multiple events, multiple working tasks and other conditions happen, communication errors easily occur in telephone communication or important working information is missed, and the normal development of work is influenced;

2. the centralized control center of the cascade power plant has more and complicated processing works, which mainly comprise power production work, maintenance and defect elimination work, water and rain condition work, early warning work, related report work and the like, and the work development is influenced by the conditions that the work is easy to have errors or the important work is not well handed over when the on-duty personnel face more and complicated work;

3. the on-duty scheduling operation is generally divided into three shifts, each shift has fixed work which must be finished within a specified time, otherwise, the work can be taken into examination;

4. at present, main working records are distributed in a plurality of places, some are computer document records, some are web page records, some are paper records, and some are orally transmitted, so that the conditions of record loss, record errors and the like easily occur in a long-term process, and the development of work analysis, accident recall and other work is influenced;

5. the number of workers is small, the workload is large, and particularly when the workers ask for a false, all scheduling operation work cannot be well carried out;

6. in the flood season, the water and rain condition work is superposed with the flood control and flood discharge work, so that the scheduling operation personnel on duty cannot carry out any work.

7. Under the condition of more work tasks and larger workload, during the shift period, due to the fact that records are more and complicated or other reasons, work errors caused by the fact that important work is not well shifted can be caused, and the important work can be possibly examined by network dispatching in serious situations, so that great economic loss is caused.

8. Between step power plant centralized control center and the step power plant, during work applications such as work application, disappearance application, have the place of part non-standardization, for example verbal application, the not scheduling problem of the same time application situation.

Based on the above problems, the conventional scheduling duty mode needs to be improved, so that a complete system for scheduling duty, including power scheduling, reservoir scheduling and work management of a cascade power plant, is needed to be provided, so as to ensure the development of scheduling work under the conditions of saving manpower and reducing management cost.

In the following, specific embodiments of the present invention will be described in more detail with reference to the accompanying drawings, which illustrate representative embodiments of the invention and do not limit the invention.

In one embodiment of the invention, a basin cascade power plant centralized control center dispatching on-duty interaction management system and a use method are provided, and the use method can be used for the basin cascade power plant centralized control center dispatching on-duty interaction management system. The system can classify and display various information related to duty according to the importance levels after receiving the information, and then the duty personnel can participate in the system to carry out work arrangement, so that the work can be carried out according to the importance levels, and the omission can be avoided during duty transfer.

It should be noted that the use method provided in this embodiment includes a use method in which a worker operates the central control center dispatching duty management system of the drainage basin step power plant, and a control use method of the system itself.

The operation method for controlling the system is mainly some operations when workers use the system. For example, when the start-up and shutdown sequence is set, a worker can set the start-up and shutdown sequence of the generator set of the power plant with the cascade watershed according to the actual operation condition and the personal work experience condition, and can optimize the start-up and shutdown sequence in the actual operation process, which are all operation methods for using the system by the worker.

The control and use method of the system is mainly some operations of the system which are automatically operated after the setting of the staff is completed. For example, when some work is not completed within a specified time, the system may send a work prompt to prompt a worker to view and complete the work in time (e.g., a start-stop prompt). After the starting and stopping sequence of the power plant in the river basin cascade is set, the system can monitor the starting and stopping conditions and automatically compare power generation plans, when the power plant needs to be started, the power generation set does not run in a grid-connected mode, and the system can automatically prompt workers to start and stop in time.

Specifically, as shown in fig. 1, the system for managing dispatching and on-duty interaction of a centralized control center of a drainage basin cascade power plant in the embodiment includes: the monitoring system comprises a monitoring system data receiving device 200, a cascade power plant production information receiving device 300, a weather condition receiving device 400, a remote measuring information receiving device 500, an information issuing device 600 and a scheduling on-duty interaction management system host 100.

The monitoring system data receiving device 200 is configured to receive monitoring data of a monitoring system;

the information receiving device 300 for production of the cascade power plant is used for receiving information for production of the cascade power plant in the drainage basin;

the weather condition receiving device 400 is used for receiving weather information;

the telemetry information receiving device 500 is used for receiving telemetry information;

the information distribution apparatus 600 is used for distributing information;

the dispatching on-duty interactive management system host 100 is in signal connection with the monitoring system data receiving device 200, the information receiving device 300 for the production of the cascade power plant, the weather condition receiving device 400, the telemetering information receiving device 500 and the information issuing device 600.

In the present embodiment, the scheduling on-duty interaction management system host 100 is configured to: receiving monitoring data of a monitoring system data receiving device 200, production information of a cascade power plant production information receiving device 300, weather information of a weather condition receiving device 400 and telemetering information of a telemetering information receiving device 500; all the jobs required by the attendant are collated based on the received information, classified according to the importance level, and issued by the information issuing apparatus 600.

In the embodiment, the monitoring system is a system for controlling, monitoring and adjusting the step power plant generator set by the central control center of the river basin step power plant. The monitoring system can control equipment of the step power plant generator set, and can control the equipment of the step power plant generator set, such as start-up and shut-down, load regulation, related power generation operation and the like. The monitoring system is provided with a master control center and a sub-control center corresponding to each step power plant generator set. In practical application, control information of the monitoring system is sent by the master control center, and after the sub-control centers of the generator sets of the cascade power plant receive corresponding signals, the corresponding automation devices can be controlled to execute relevant operations.

The operation information and relevant operation parameters of all equipment in the cascade power plant generator set are transmitted to the monitoring system, and the monitoring system data receiving device can receive relevant data and transmit the relevant data to the dispatching on-duty interaction management system host. Therefore, staff of the central control center of the drainage basin cascade power plant can monitor the power generation operation state by means of the monitoring system and can check all operation information needing to be checked.

Illustratively, a master control center of the monitoring system and a dispatching duty management system of the central control center of the river basin cascade power plant are both arranged in a central control room of the central control center of the river basin cascade power plant, sub-control centers of the monitoring system can be arranged in a plurality of operator stations, the operator stations can display relevant information of the monitoring system and provide an operation platform for the monitoring system, and workers can control, monitor and adjust the generator set of the cascade power plant in the operator stations by means of the monitoring system.

The monitoring system and the dispatching duty management system of the river basin cascade power plant centralized control center run independently, and the two systems are both provided with hardware equipment which are independent of each other. In practical use, the dispatching duty management system of the central control center of the drainage basin cascade power plant can only fetch relevant operation data from the monitoring system according to requirements. In order to improve the safety performance, the monitoring system is provided with a database for storing data, the database can be divided into 4 areas, wherein the first area and the second area are mainly used for storing control and regulation data and the like, the third area is mainly used for storing operation data information, information called by the central control center dispatching duty management system of the drainage basin step power plant from the monitoring system is stored in the three areas, and the fourth area can be used for standby.

It can be understood that, in the centralized control room of the central control center of the valley cascade power plant, the staff can operate both the dispatching duty management system of the central control center of the valley cascade power plant and the monitoring system, for example, the staff can use the dispatching duty management system of the central control room to manage the daily work of the staff of the central control room, and can also use the monitoring system to manage the control regulation, the knife gate operation and the like of the generator set of the valley cascade power plant. The two sets of systems are not interfered with each other, and the connection between the two sets of systems is that when the connection is needed, the dispatching duty management system of the central control center of the drainage basin cascade power plant can fetch and use part of data of the monitoring system.

Further, in this embodiment, in the process of using the central control center of the river basin cascade power plant to schedule the on-duty management system, the staff not only needs the relevant data information in the monitoring system, but also needs a large amount of cascade power plant production information, which cannot be directly retrieved from the monitoring system, and needs the staff of the cascade power plant to report, or receives the cascade power plant production information through the information receiving device for cascade power plant production.

The information receiving device for the production of the cascade power plant can receive the information, and the information which can be directly called from the monitoring system such as control information, operation parameter information and the like of the generator set does not need to be received by the device.

In this embodiment, the production information of the watershed cascade power plant, which needs to be received by the production information receiving device of the cascade power plant, mainly includes: the method comprises the steps of step power plant generator set maintenance information, power generation equipment defect information, a power generation equipment defect elimination plan, a step power plant working plan, one or two electric working tickets of the step power plant and the like.

In practical application, the central control center of the power plant with the river basin cascade needs to master weather conditions in the later period in time, so that work such as power generation planning and start-stop mode determination can be efficiently carried out. Therefore, the weather condition is a relatively important information for the centralized control center.

The range of the weather condition is mainly within the range of the cascade power plant control basin, and the weather condition outside the range has little influence on the water and rain condition of the basin.

The weather conditions are mainly late weather conditions, i.e. weather forecasts. The method mainly comprises the following steps: late rainfall condition, late temperature condition, whether extreme weather exists, important weather forecast, etc. And the staff of the centralized control center of the power plant with the cascade drainage basin is convenient to compile a power generation plan, a maintenance plan and the like according to the weather information.

The weather condition in the river basin can generate great influence on precipitation and reservoir evaporation in the river basin, particularly the rainfall condition in the river basin is information which is mainly concerned by operators on duty, and when the river basin falls, the operators on duty need to take precautionary measures in time to prevent strong rainfall or too fast water level rising. In addition, in a large-scale high-temperature or severe cold weather, the power generation condition of the cascade power plant in the drainage basin is also greatly influenced, the staff of the centralized control center needs to master the weather condition in the large scale, and in a continuous high-temperature or severe cold weather, the cascade power plant needs to keep large-load power generation or long-term large-load power generation, and needs to check the equipment of the generator set in advance in time to prepare for long-term operation.

In this embodiment, the weather condition receiving device can receive weather information within the scope of the control basin of the cascade power plant.

The cascade power plant in the drainage basin is a relatively large drainage basin, and a multi-stage power plant is arranged in the drainage basin. The staff of the step power plant centralized control center needs to master the actual rainfall condition in the flow area and the water level condition of the reservoir of each step power plant, so that the staff can conveniently and timely carry out reservoir dispatching work.

In the present embodiment, the telemetric information receiving apparatus can receive telemetric information including rainfall information and water level information. Specifically, the method comprises the following steps:

for rainfall information, a plurality of rainfall stations can be arranged in a flow domain, the rainfall is measured once per hour, data are transmitted to the telemetering information receiving device, and workers can check the rainfall information of each station. The rainfall information of some non-measured rainfall stations such as surface rainfall information, rainfall in intervals between reservoirs and the like needs to be calculated by corresponding formulas, and the required rainfall is calculated. The rainfall measuring of each rainfall station is a special rainfall measuring device;

for water level information, which is mainly upstream and downstream water level information of a cascade power plant reservoir, centralized control center workers need to perform water level control to ensure safe and stable operation of the cascade power plant in the drainage basin. The water level information is not only used for monitoring by the staff, but also used when the related flow rate is calculated.

The information issuing device is built in a dispatching duty interaction management system of a central control center of a drainage basin step power plant, is equivalent to an information sending module, and can send information to the outside when the system needs.

The information distribution device can distribute information in various ways, and the main distribution ways include a short message way, a telephone way, a facsimile way and the like.

Illustratively, the information issuing device can directly send short messages and make calls, and when the system is connected with a printer with a fax function, the information issuing device can also send related information in a fax mode according to instructions.

It can be understood that the dispatching duty interaction management system of the river basin cascade power plant centralized control center is applied to the cascade power plant centralized control center, workers need to process and examine related working items of some cascade power plants, and in the process of processing the working items, when abnormal conditions occur or the working time limit is reached but the completion is not completed, the reminding needs to be performed, at the moment, the dispatching duty interaction management system of the river basin cascade power plant centralized control center can send related information to the workers and the like by means of an information issuing device.

Preferably, the dispatching on-duty interaction management system for the central control center of the drainage basin cascade power plant can be internally provided with release grades of different information, and once information needs to be sent to workers and the like, the system can determine the information release form and time according to the release grades of the different information and the different workers on duty.

Therefore, in actual use, the dispatching on-duty interaction management system host 100 can receive various data related to the operation of the cascade power plant, and meanwhile, the host can arrange all the works needing to be carried out by the on-duty personnel based on the data, classify and sort the works according to the importance degree of each work, and send each work needing to be carried out to the on-duty personnel in time and order, so that the on-duty personnel can carry out work arrangement according to the information provided by the system. The system can ensure that the work content can be carried out in sequence according to the importance degree, can also avoid missing during shift switching, and can also reduce the labor intensity of workers and improve the working quality and the working efficiency of the workers.

In addition, under the mode that few people are on duty, the working intensity of the person on duty is high, the working pressure is high, and after the system is used, the working pressure of the person on duty can be greatly reduced, and the working efficiency and the working quality are improved. Through the operation of the system, the person on duty can also make optimization scheduling work, adjust the power generation condition in time, avoid the condition of flood discharge, and can ensure that the downstream of the reservoir is free from the influence of flood disasters. Meanwhile, the system carries out statistical analysis and gives a reasonable operation mode suggestion, so that not only can the safe and stable operation of the unit be ensured, but also the ecological flow requirement of a basin can be ensured.

In order to better save various items of data, as shown in fig. 1, in this embodiment, the system further includes: the schedule on duty interaction manages the system database 700. The scheduling on-duty interaction management system database 700 is in signal connection with the scheduling on-duty interaction management system host 100, and the scheduling on-duty interaction management system database 700 can receive and store data from the scheduling on-duty interaction management system host 100.

In addition, in order to facilitate the staff of the centralized control center to process the data and information of the whole system in time and facilitate the staff of the cascade power plant to update the data of the whole system in real time, as shown in fig. 1, in this embodiment, the system further includes: a centralized control center operator 800 and a step power plant operator 900. The central control center operating device 800 and the cascade power plant operating device 900 are in signal connection with the dispatching on-duty interactive management system host 100, and the central control center operating device 800 and the cascade power plant operating device 900 can receive operating signals of operators on duty so as to process data in the dispatching on-duty interactive management system host.

It can be understood that the central control center operating device 800 is disposed in a central control room (or also called a central control center operator station) of the central control center of the drainage basin step power plant, and an operator can operate the central control center dispatching duty management system of the drainage basin step power plant at the central control center. The step power plant operation devices 900 are respectively arranged in control rooms (or also called step power plant operator stations) corresponding to the generator sets of the step power plant, and workers can operate the centralized control center dispatching duty management system of the step power plant in the drainage basin in the step power plant.

In order to enable the scheduling on-duty interaction management system host 100 to determine the work content of the worker based on the operation condition of the cascaded power plant, in the embodiment, as shown in fig. 2, the scheduling on-duty interaction management system host 100 is configured with an electric power production management module 110, and the electric power production management module 110 is configured to organize information related to work and management related to electric power production.

Illustratively, the power production management module stores:

(1)96 point power distribution plan

The 96-point power generation plan refers to setting a point every 15 minutes, and accumulating 96 points 24 hours a day. The daily power generation schedule is refined to each plant so that each plant has a 96 point power generation schedule.

Moreover, the power generation management module can refine the 96-point power generation plan and display the power generation plan in the scheduling on-duty interactive management system, for example, the power generation plan can be displayed in a curve form through a display screen connected with the scheduling on-duty interactive management system, and an operator on duty can visually see the power generation plan. In practice, a prompt can be given at the time point of startup and shutdown, for example, in a power plant a, when one generator is in grid-connected operation, the maximum load is 84MW, and when the power generation is planned to be 100MW at the next moment, another generator needs to be started in grid-connected operation, at this moment, the module can prompt an operator on duty to start up, and give a load distribution prompt, so as to ensure the safe and stable operation of the unit.

(2) Start-up and shut-down sequence

The cascade power plant centralized control center is responsible for dispatching and running of a plurality of generators, and because the number of units is large and the units are distributed in a plurality of power plants, the health condition of each unit device is different, and sometimes, the condition that some device defects cannot be eliminated in time exists, so that the starting and stopping sequence of each power plant is different.

Therefore, the power production management module is provided with a start-up and shut-down sequence reminding function. When the power plants in the different steps need to be started and shut down for sequencing, the power plants in the different steps can be sequentially registered in the power production management module, and then the power plants are pushed to the on-duty personnel of the centralized control center by the aid of the information issuing device and are displayed to the on-duty personnel of the centralized control center, and the on-duty personnel can execute the starting and shutting down according to the sequence.

Certainly, in other embodiments, the on-duty personnel of the centralized control center can also perform the sequencing of the startup and shutdown of the cascade power plant according to the conditions of power generation requirements, rainfall, weather and the like, and then execute the sequencing according to the sequence.

(3) Generated energy

The power production management module can display the real-time power generation amount and the previous day power generation amount of each cascade power plant in a curve mode through a display screen connected with the dispatching duty interactive management system, comparison is made, and a duty worker can visually check the power generation condition. Further, information such as the monthly accumulated power generation amount, the annual accumulated power generation amount, and the perennial average power generation amount can be displayed in the form of a graph.

(4) Electrical quantity control

According to specific production conditions and power grid requirements, when the daily power generation amount cannot exceed or be less than the daily power generation amount, or the power generation amount is a fixed value, the power control setting can be performed in the power generation management module, all power generation amount control requirements are set, the system can automatically calculate to determine the daily power generation condition, and a worker can perform power generation arrangement according to the calculation result or perform power generation arrangement by himself.

Because the generated energy is related to the businesses of all departments of the company, the related departments of power generation production, the related departments of power market, the dispatching and operating departments and the reservoir operation management departments can all inquire information and request for demands.

(5) Special power generation operating requirements
