Problems solved by technology

[0003] In the existing fault repair methods, the fault repair strategy is mostly determined by the staff based on experience and historical fault repair records, and then repaired by the power operation and maintenance inspection personnel, or the fault repair strategy is issued and executed through the repair system, resulting in the repair strategy The adaptability is low, and the degree of automation and reliability of execution is low, which prolongs the recovery time of the power system; the fault monitoring is mostly limited to the local power system, the repair strategy is relatively single, and the reliability of the repair method is poor; the repair process is usually Executed by a single regional power grid, the overall restoration strategy cannot be completed, resulting in low restoration efficiency

Abstract

The invention relates to a power system fault automatic restoration method and device based on multi-station cooperation, and the method comprises the following steps: S1, monitoring fault information, S2, controlling a main station to generate a fault restoration strategy, S3, controlling a substation to decompose the fault restoration strategy, and S4, controlling the substation to decompose thefault restoration strategy. The method specifically comprises the steps: enabling a control substation to decompose a repair strategy according to the number of controllable elements within the control range of the control substation to obtain a repair sub-strategy, and sending the repair sub-strategy obtained through decomposition to an execution station; S4, enabling the execution station to execute the restoration sub-strategy and calls parameters in the restoration sub-strategy to perform restoration operation on the element.

Description

technical field [0001] The invention belongs to the technical field of power system fault repair, and relates to a power system fault repair method and device, in particular to a power system fault automatic repair method and device based on multi-station coordination. Background technique [0002] With the continuous development of the economy and the increase of power demand, the scale of the power grid and the number of equipment are increasing day by day, which makes the task of fault repair in the power system also increase. When the system fails, it is first necessary to obtain the fault information to determine the location and components of the fault; and then specify the relevant fault repair method according to the fault information; the repair work of the system fault should have high reliability and timeliness to ensure the power supply The system restores normal power supply as soon as possible. [0003] In the existing fault repair methods, the fault repair st...
