摘　　要：在电力系统仿真软件Matlab/simulink中建立了静止无功补偿型发电机组的模型,仿真计算在一个由5台风电机组构成的风电系统中进行。风电机组是带有静止无功补偿(英文简称SVC)的异步风电机组,SVC装置对电机端电压有一定的支撑能力。风电场升压变压器的低压侧装SVC,可以减轻风电机组并网过程中对系统的冲击,电压从并网到稳定所经历的时间较不加装SVC者短,实现了恒速风力发电机组的柔性并网。The compensation wind turbine model with the static var compensator （SVA） was established in the power system simulation software Matlab/Simulink. Simulation calculation was done in a power system made up with 5 sets of the wind turbine. The wind turbine was composed of asynchronous wind turbine generator compensated by the static var compensator （SVA）, which possessed the ability to support the terminal voltage. If the SVA was equipped at the low voltage end of the boosting transformer of the system, the shock by the wind turbine sets to the system would be decreased during linking to it. The period of becoming stable from initial linking for the sets equipped with SVA would be less than that of without SVA, so as to realize the flexible linkage of the constant speed wind turbine set.
