| 研究了基于双馈感应电机(doubly-fed induction generator,DFIG)的电压源高压直流输电(voltage source convertor-high voltagedi-rect current,VSC-HVDC)系统的风电并网技术。为解决风电并网运行存在的电压稳定性的问题,通过对风电机组无功电压特性的分析,提出了无功补偿电容量的不同投切方法和计算方式。结合风电场无功需求的特点,应用静止无功补偿器(StaticVarCompensator,SVC)进行无功补偿优化。利用Matlab/Smiulink仿真软件对该方案进行了仿真分析。仿真结果表明:SVC可以提供动态电压支撑,能够降低风电功率波动对电网电压的影响,改善系统运行性能,确保电网安全稳定。 |
