摘要
在电力系统仿真软件DIgSILENT/PowerFactory中建立了静止无功补偿器(static var compensator,SVC)补偿型定速风电机组的模型,分析了其稳态和暂态特性以及由SVC补偿型风电机组组成的风电场对电网的影响,分别采用上述风电机组模型和用电容器组进行补偿的普通定速风电机组模型进行仿真实验,比较结果表明SVC补偿型风电机组具有快速调节无功功率的能力,当系统故障时,该风电机组可快速恢复系统电压,且风电机组启动过程对系统的冲击较小。
The fixed speed wind turbine model with static var compensator （SVC） is established in the power system simulation software DIgSILENT/PowerFactory, and its steady and transient characteristics as well as the influence of wind farm consisting of wind turbines with SVC on power grid are analyzed. Comparison results of above-mentioned wind turbines with SVC and common fixed speed wind turbine compensated by capacitor bank show that the former possesses the ability of quickly adjusting reactive power and its power factor can vary with a larger range; high voltage recovery speed while power grid is faulty; and smaller impact to power grid while the wind turbine with SVC is started up.
