Description

Technical Field

[0001] The present invention relates to the technical field of electric power systems, and in particular to a dispatching automation duty auxiliary system and an auxiliary control method. Background Art

[0002] With the rapid development of social economy, the scale of electricity consumption has greatly expanded, and the number of new and renovated substations has gradually increased. The number of "four remote" signals that need to be checked by the power grid dispatching automation system has increased rapidly, and the responsibility is becoming increasingly heavy. With the huge increase in the amount of information that needs to be checked by "four remote", the debugging tasks of the automation operation and maintenance personnel in the power grid dispatching automation system are becoming increasingly heavy, and there is a risk of missing signal verification after a large amount of data flushes the alarm window.

[0003] In the power grid dispatching automation system, the traditional paper-based signal debugging records no longer meet the requirements. At present, there are shortcomings such as the difficulty in recording and archiving erroneous telesignals and telemetering points during the debugging process. And with the advancement of science, the OCS system (real-time control system) is configured in the power system, so the automation master station operation and maintenance personnel are required to inspect the operation of the power system every day. The inspection frequency is getting more and more frequent. The operation of the OCS system and the dynamic environment system of the machine room makes the inspection pressure increase day by day, and it is impossible to systematically classify the problems found during the inspection. The on-duty personnel of the operation and maintenance need to spend a lot of time to fill in and record the problems of the inspection, so that the on-duty automation personnel cannot obtain historical defect data in time to deal with the defects of the power system in time, thereby affecting the efficiency of defect processing and causing repeated system defects in the power system. Summary of the invention

[0004] In order to overcome the problems existing in the background technology, the purpose of the present invention is to provide a dispatching automation duty auxiliary system and an auxiliary control method, which can replace the duty staff to complete the inspection work of the power system.

[0015] In combination with the first aspect, further, when the following determination conditions are met, it is determined to be an emergency state:

[0016] F>1.5f(1+S%)

[0017] In the formula, F represents the peak value of the collected power operation data, f represents the peak value of the previous power operation data, and S% represents the average annual growth rate.

[0018] In combination with the first aspect, further, when a level 2 safety alarm state occurs, the early warning module issues a level 2 safety alarm;

[0019] When a level one safety alarm state occurs, the early warning module issues a level one safety alarm;

[0020] When an emergency occurs, the early warning module issues an emergency alarm;

[0027] According to the accident handling analysis results, the control computer system skips the dispatching automation system and directly makes automatic decisions and self-controls on the status of the power system.

[0028] In conjunction with the second aspect, further, a method for collecting power operation data in real time from a dispatching automation system includes:

[0029] Mybatis is used to collect real-time data from the database of the dispatching automation system containing power operation data.

[0040] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0041] Embodiment 1:

[0042] like Figure 1 As shown, a dispatching automation duty auxiliary system is characterized by comprising a terminal control system, wherein the terminal control system comprises:

[0043] Data acquisition module: used to collect power operation data in real time from the dispatching automation system;

[0044] Data classification module: used to classify the power operation data into security levels;

[0045] Accident handling and analysis module: used to analyze abnormal power operation data according to the safety level classification results and obtain accident handling and analysis results;

[0046] Early warning module: used to output early warning warnings based on accident handling analysis results;

[0047] Automatic control system: It is used to control the computer system to skip the dispatching automation system and make automatic decisions and control the state of the power system directly according to the analysis results of accident handling.

[0048] The terminal control system uses the data acquisition module to collect the power operation data in the dispatching automation system, and timely classifies and processes the collected power operation data through the data classification module. The collected power operation data is timely analyzed through the accident processing and analysis module. When abnormal power operation data is analyzed, the early warning module issues an early warning alarm for the abnormal power operation data. The duty auxiliary system realizes the integrated classification, analysis and early warning alarm of the power operation data collected in the dispatching automation system.

[0049] like Figure 1As shown, the data acquisition module adopts Mybatis to collect the database containing power operation data from the database of the dispatching automation system in real time. Using Mybatis to collect the power operation database from the dispatching automation system in real time can save the working cost of the on-duty personnel in real time collecting the power operation database, and on the other hand, improve the work efficiency and work quality, and ensure the accuracy of the power operation database collection. The power operation data includes the current of the outgoing switch, the voltage of the incoming bus, the reactive power of the transformer, the fluctuation range of the three-phase electricity, the frequency of the system, the peak and valley values ​​of the system load and the annual average growth rate of the system.

[0050] like Figure 1 As shown, the safety level includes emergency state, level 1 safety alarm state, level 2 safety alarm state and level 3 safety state. When the following determination conditions are met, it is determined to be an emergency state:

[0051] F>1.5f(1+S%)

[0052] In the formula, F represents the peak value of the collected power operation data, f represents the peak value of the previous power operation data, and S% represents the average annual growth rate.

[0053] When a level 2 safety alarm state occurs, the early warning module issues a level 2 safety alarm; when a level 1 safety alarm state occurs, the early warning module issues a level 1 safety alarm; when an emergency accident state occurs, the early warning module issues an emergency alarm; when the early warning module issues an emergency alarm for more than five minutes without a response, the automatic control system directly controls the computer system to skip the dispatching automation system to make automatic decisions and self-control on the power operation data in the power system that has analyzed the abnormality, thereby completing the closed-loop control of the power system, reflecting the strong safety factor of the duty auxiliary system.

[0054] Embodiment 2:

[0055] like Figure 1-2 As shown, an embodiment of the present invention provides an auxiliary control method for a dispatching automation duty auxiliary system, which can be implemented by using the auxiliary system as described in Example 1. The method includes the following steps:

[0057] Classifying the power operation data into security levels;

[0058] Analyze abnormal power operation data according to the safety level classification results and obtain accident handling analysis results;

[0059] Output early warnings based on the accident handling analysis results;

[0060] According to the accident handling analysis results, the control computer system skips the dispatching automation system and directly makes automatic decisions and self-controls on the status of the power system.

[0061] like Figure 1 As shown, the method for collecting power operation data in real time from the dispatching automation system includes:

[0062] Mybatis is used to collect real-time data from the database of the dispatching automation system containing power operation data.

[0063] For power operation data that cannot be collected in real time, the following method is used to calculate and obtain it:

[0064] The power operation data of each substation in the distribution network on a set historical date is collected from the dispatching automation system. For each substation in the distribution network without real-time measurement and collection, the real-time power operation data of the substation is calculated by interpolation method.

[0065] Working principle: The data acquisition module inside the terminal control system uses Mybatis to periodically collect the power operation data of each substation in real time within the dispatching automation system. The collected power operation data is classified by the data classification module for safety level and analyzed by the accident handling analysis module. When an emergency occurs, the early warning module issues an emergency alarm. When there is no response after the emergency alarm is issued for more than five minutes, the automatic control system in the terminal control system directly controls the computer system to skip the dispatching automation system to make automatic decisions and self-control on the power operation data in the power system that has analyzed the abnormality.
