摘　　要：针对目前风电场单独采用静止无功补偿器(SVC)或静止无功发生器(SVG)的缺陷,设计了一个由大容量SVC和小容量SVG组成的联合动态无功补偿系统。首先,阐述了联合动态无功补偿系统的结构;其次,对本文采用的无功协调控制策略进行了分析;最后,结合实际风电场参数,对联合动态无功补偿系统进行了仿真实验分析。实验结果验证了联合动态无功补偿系统补偿的有效性和合理性。In view of the defects caused by Static Var Compensator （SVC） or Static Vat Generator （SVG） used alone in wind farms, a combined dynamic reactive power compensation system consisting of a large capacity SVC and a small capacity SVG is designed in this paper. Firstly, the structure of the combined dynamic reactive power compensation system is described; secondly, the strategy of the reactive power coordination control system used in this paper is analyzed; finally, simulation is conducted for the combined dynamic reactive power compensation system with actual parameters of a wind power farm considered. The results of the simulation show that the combined dynamic reactive power compensation system is both valid and rational.
