An active closed-loop monitoring information source maintenance method

Abstract

The invention discloses an active close-loop monitoring information source end maintenance method. The active close-loop monitoring information source end maintenance method includes automatically synchronizing a monitoring information maintenance plan to a regulation system of a first safety area; analyzing the monitoring information maintenance plan through the regulation system, and providing authorization to a substation background monitoring system according to content of the monitoring information maintenance plan; maintaining monitoring information according to authorization content; after completing maintenance, enabling the substation background monitoring system to automatically generate a latest monitoring information model and a latest graphic file, and trigger a maintenance and update ending signal; after the regulation system receives the maintenance and update ending signal, summoning the latest monitoring information model and the latest graphic file, and updating a monitoring information model and a graphic file in the regulation system. By maintaining an active close-loop source end of the monitoring information, the active close-loop monitoring information source end maintenance method greatly reduces a workload of monitoring information maintenance, guarantees timeliness and consistency of monitoring information updating of a master station and branch stations, and can effectively avoid safety problems of monitoring missing, or even mistaken monitoring, caused by unsynchronized updating of the monitoring information.

Description

technical field [0001] The invention relates to an active closed-loop monitoring information source end maintenance method, which is used in a smart grid dispatching control system to perform active closed-loop maintenance on the monitoring information of the smart grid regulation system, and belongs to the technical field of electric power dispatching automation. Background technique [0002] With the continuous deepening of the construction of the "big operation" system of the State Grid Corporation of China, the operation mode is shifting towards the integration, intensification, and leanness of dispatching, monitoring, and operation. . At the same time, with the rapid expansion of the grid scale and the rapid increase in the number of substations put into operation, the amount of monitoring information in the control automation system continues to rise, which puts forward higher requirements for the daily maintenance and processing of massive monitoring information in th...

AI Technical Summary

Problems solved by technology

On the one hand, sub-stations lack efficient active processing methods for monitoring data. After receiving maintenance information, they need to be processed manually, resulting in a huge monitoring workload and low work efficiency; on the other hand, due to the physical isolation between the first and third security areas , the information maintenance plan entered by the monitoring personnel in the safety three-zone control system monitoring system cannot be automatically synchronized to the safety one-zone control system for maintenance operations in time, resulting in the inability of substations to respond in time and complete the planned operation

At the same time, the system also lacks effective authorization management means for the monitoring operation of the substations of the substation. Once the monitoring information of the substation is modified, the main station does not update it in time, which may lead to missing monitoring or even miscontrolling, and there are great security risks.
