Configuration method and system for reactive power compensation of wind power plant

Abstract

The invention discloses a configuration method for reactive power compensation of a wind power plant. The configuration method for reactive power compensation of the wind power plant comprises the following steps that electrical data of the wind power plant are acquired; the maximum capacitive reactive power and the maximum lagging reactive power of the wind power plant are measured according to the electrical data and a preset wind power plant electrical simulation model; the type of a reactive power compensation device is determined and the reactive power compensation capacity of the reactive power compensation device is calculated according to the electrical data, the maximum capacitive reactive power, the maximum lagging reactive power and the reactive power regulation capacity of a draught fan, wherein the reactive power compensation device comprises a parallel reactor, a parallel capacitor and / or an SVA device; the reactive power compensation device with the reactive power compensation capacity is installed and configured on a grid connection point of the wind power plant. The invention further provides a system corresponding to the configuration method. By the adoption of the system, the type and the capacity of reactive power compensation can be determined rapidly, easily and conveniently.

Description

technical field [0001] The invention relates to the technical field of wind farms, in particular to a configuration method for wind farm reactive power compensation and a configuration system for wind farm reactive power compensation. Background technique [0002] As the global energy crisis continues, new energy, especially wind power, is developing rapidly around the world. Compared with land wind power, offshore wind farms have the advantages of good wind resources, high annual power generation, and less land occupation. They have developed rapidly in recent years. [0003] In the research and design of offshore wind farms, reactive power compensation is a very important issue, which directly affects the power factor and voltage level of the wind farm being assessed, as well as the reactive power support capability of the wind farm. For the reactive power configuration of offshore wind farms, including the type selection, capacity selection, and location selection of reac...
