A method and device for determining a power grid accident plan

Abstract

The embodiment of the invention provides a preliminary plan determining method and apparatus of a power grid accident. The method comprises: a grid accident signal is monitored and a fault device and a fault device title are determined according to the grid accident signal; on the basis of the fault device title, searching is carried out on a preset accident preliminary plan model to obtain standby preliminary plans, wherein the accident preliminary plan model contains titles of all fault devices and preliminary plans corresponding to the titles of all fault devices; checking is carried out on all standby preliminary plans according to a preset checking rule to obtain a checked preliminary plan, wherein the operating way of the device corresponding to the checked preliminary plan is identical with the operating way of the fault device after isolation, and the checked preliminary plan is used as a formal preliminary grid accident plan of the fault device. Therefore, a needed preliminary plan can be searched rapidly and accurately. Meanwhile, the searched preliminary plan is checked, so that a problem that the searched preliminary plan is not suitable for the accident because of the large change of the grid topological structure can be solved; and thus safety of the power grid is improved.

Description

technical field [0001] The invention relates to the technical field of power grid dispatching, in particular to a method and device for determining a power grid accident plan. Background technique [0002] At present, when an accident occurs in the power grid, the dispatcher mainly relies on the existing accident plan to deal with the accident. When the dispatcher monitors the power grid accident signal through the SCADA (Supervisory Control And Data Acquisition, data acquisition and monitoring control) system, after judging and locating the faulty equipment, manually retrieve and identify all the accident plans. After identifying the corresponding plans, Then carry out a series of follow-up operations (such as load transfer, fault isolation and restoration of power supply) according to the plan. [0003] After the accident, through manual identification and search for contingency plans, due to the limited human energy and identification and search speed, it will take a lon...

Problems solved by technology

[0004] In view of this, the embodiments of the present invention provide a method and device for determining a power grid accident plan to solve the problem of prolonging the time for dealing with power grid accidents in the prior art by manually identifying and searching for a plan, and because the topological structure of the power grid often occurs large After the plan is identified and searched, the scheduling plan obtained after the search may no longer be suitable. At the same time, the correctness of the relevant operations in the process of identifying and searching for the plan cannot be guaranteed through manual methods, so that the final plan obtained is not the best. A good plan, which brings great hidden dangers to the safe operation of the power grid
