Abstract

The application provides a reactive power compensation optimizing configuration method and a reactive power compensation optimizing configuration system. A problem of transient voltage instability in an electric power system is solved from an angle of dynamic reactive power compensation according to low voltage maintenance time of each node in each fault condition. An optimal compensation place and optimal compensation capacity can be obtained via two optimizing models established by the reactive power compensation optimizing configuration method and the reactive power compensation optimizing configuration system, a global optimal compensation result is obtained, and system operation safety and stability are ensured.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a reactive power compensation optimal configuration method and a reactive power compensation optimal configuration system. Background technique [0002] In recent years, many blackouts worldwide have been caused by voltage instability. Moreover, with the continuous improvement of the complexity and voltage level of the power grid, the increasing load and the continuous implementation of AC-DC interconnected large power grids, the problem of transient voltage instability after a fault in the power system has become increasingly prominent. [0003] A key factor leading to the transient voltage instability problem is the insufficient dynamic reactive power support of the power system. Although there are some studies on the optimal configuration of system reactive power compensation, most of them use the analysis method of static voltage stability; For example, after a transie...
