Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0033] Such as figure 1 As shown, a regional power grid online fault handling plan generation method, including the following steps:

[0034] Step 1. Collect faulty device information.

[0035] In the case of an abnormality in the power grid, use real-time periodic scanning to obtain fault equipment information extracted from fault alarm information or fault equipment information preset on the plant and station diagram; obtain power grid model information and equipment in the dispatching control system Telecommunication and telemetry data, equipment parameters, node connection relations, etc., establish an initial section for fault recovery analysis.

[0036] Faulty equipment information main...

Abstract

The invention discloses a regional power grid online fault handling plan generation method which comprises the steps: analyzing a tripping switch around fault equipment according to fault equipment information and a power grid topological structure; searching a power loss substation and a power loss bus thereof from the tripping switch according to the topological structure of the power grid; generating a power restoration plan of the power loss substation and the power loss bus thereof according to a preset power restoration principle; and performing risk assessment on all the power restoration plans, and taking the optimal power restoration plan as a final fault handling plan. The invention further discloses a corresponding system. According to the method, the power loss station and thepower loss bus of the power loss station are searched to generate the power restoration plan according to the fault equipment information and the power grid topological structure, risk assessment is performed on the power restoration plan, and the optimal power restoration plan is obtained according to the assessment result to serve as the final fault handling plan. Compared with plans generated through a traditional method, the method is more reasonable and comprehensive, and the capacity of the dispatcher for handling major faults of the power grid is greatly improved.

Description

technical field [0001] The invention relates to a method and system for generating an online fault handling plan for a regional power grid, and belongs to the technical field of intelligent analysis and control of electric power systems. Background technique [0002] At present, problems such as complex operation mode of the power grid, heavy equipment load, and insufficient power supply capacity are becoming more and more prominent. The pressure on the safe operation of the power grid is increasing day by day. [0003] In the handling of dispatching operation accidents, it is necessary to quickly provide the optimal plan for handling power outages. As the regional power grid expands day by day, when dispatchers search for power supply paths for power outage loads, there will inevitably be omissions and negligence in the power supply paths obtained only by observation and experience. , so there is an urgent need for a new fault handling plan generation method.
