Wind farm reactive comprehensive optimization control method

Abstract

The invention relates to a wind farm reactive comprehensive optimization control method. The method comprises the following steps of: inputting signals into a wind farm reactive comprehensive optimization control system; switching plant or wind farm grid combining point capacitors and reactors, controlling a static var compensator (SVC) and controlling wind farm units by using the wind farm reactive comprehensive optimization control system. Through the scheme, the automatic control level of wind farm scheduling, the utilization ratio of reactive configuration equipment and the voltage stabilization level of a power grid can be improved, and reactive power comprehensive optimization coordination control over wind farms is realized.

Description

technical field [0001] The invention relates to an automatic control of a power system and a new energy access and control method, in particular to a reactive power comprehensive optimization control method for a wind farm. Background technique [0002] With the rapid development of wind power, my country's annual newly installed wind power capacity and total installed capacity have leapt to the forefront of the world. my country's power grid has a vast area, the wind farms are scattered, there are many types of grid-connected wind turbines, and the capacity of the wind farm is large. Compared with traditional thermal power plants, wind farms generally have shortcomings such as decentralized control, low automation level, and weak dispatch control. In terms of voltage and reactive power configuration and control, some wind farms have insufficient reactive power configuration capacity and lack of control means, resulting in a low pass rate of bus voltage at grid-connected po...
