Wind farm automatic voltage control distribution method with svg

Abstract

The invention provides an SVG-containing wind power plant automatic voltage control distribution method which is used for achieving whole-plant automatic voltage control of an SVG-containing wind power plant. The SVG-containing wind power plant automatic voltage control distribution method comprises the following steps of S1 issuing a communication instruction to reactive power distribution modules of a whole plant and inputting whole-plant automatic voltage control voltage values X to the reactive power distribution modules, wherein the reactive power distribution modules in the whole plant are respectively connected with an SVG reactive power control module and a wind generation set reactive power coordination control module, and the wind generation set reactive power coordination control module is connected with a wind generation set group control module I, a wind generation set group control module II and a wind generation set group control module III. By means of the SVG-containing wind power plant automatic voltage control distribution method, quick response to whole-plant reactive control can be achieved and reactive adjusting capacity of a wind generation set is also fully utilized through reactive coordination control on an SVG and the wind generation set, and accordingly it is ensured that the wind power plant completes quick and stable reactive power control according to a dispatching instruction.

Description

technical field [0001] The invention belongs to the voltage and reactive power control technology of a wind farm, and in particular relates to an automatic voltage control distribution method of a wind farm including SVG. Background technique [0002] With the increasing scale of the power system and the country's increasing requirements for the automatic voltage control (AVC) function of the whole plant for wind farms, the national standard "Technical Regulations for Connecting Wind Farms to Power Systems" clearly requires the priority use of wind turbines Perform reactive power control. However, due to the small reactive power adjustment range of a single wind turbine and the large number of wind turbines in the wind farm, it is necessary to study a reactive power allocation method based on clustering of wind turbines to ensure smooth and rapid control. . Contents of the invention [0003] In order to solve the above problems, the present invention provides an automati...
