Abstract

The invention relates to an automatic generation method for a coordinated control area in region-county integrated automatic voltage control and belongs to the technical field of the automatic voltage control of power systems. The method comprises the following steps of generating a model of a 110kV power grid connected with a 220kV transformer of a regional power grid, and generating the coordinated control area; adding a 35kV transformer substation connected with a low-voltage side winding of the 220kV transformer of the regional power grid into the generated coordinated control area; generating a model of a county-level 35kV power grid connected with a 110kV transformer of the regional power grid, and generating a 110kV coordinated sub-control area; adding the generated 110kV coordinated sub-control area into the generated coordinated control area. According to the method, the coordinated control area for the region-county integrated automatic voltage control can be quickly and automatically formed, and the requirements on coordinated reactive voltage control over superior and subordinate transformer substations of region-county power grids are met.

Description

technical field

[0001] The invention belongs to the technical field of automatic voltage control of electric power systems, and provides a method for automatically generating a coordination control area by performing multi-level topology analysis on a power grid in the integrated automatic voltage control of prefectures and counties. Background technique

[0002] Automatic Voltage Control (hereinafter referred to as AVC, Automatic Voltage Control) system is an important means to achieve power grid security (increase voltage stability margin), economy (reduce network loss), and high-quality (increase voltage pass rate) operation. Control the reactive power output of generators, transformer taps and reactive power compensation equipment to achieve a reasonable distribution of reactive power and voltage in the grid.

[0003] The master station part of the AVC system is implemented in the power system control center based on software programs, which requires that it must be cons...
