摘要
建立了恒速异步风电机组并网电力系统、电容器组和静止无功补偿器的模型,基于PSCAD仿真分析了在各种不同的无功补偿策略下风机并网及系统故障后并网点、机端电压及风机转速的变化。结果表明,SVC比电容器组有更好的补偿效果且选择在并网点集中补偿更经济。研究结果有助于风电并网电力系统合理采用无功补偿方式。
The models of wind farm,capacitors and SVC were established on the PSCAD platform.System PCC voltage and wind generator s rotor speed and terminal dynamic voltage were analysised on the different of reactive power compensation strategy.The simulation results show that SVC play more effective and more economic in compensating PCC than capacitors,which help using reasonable compensation measure in grids interconnected wind farm.
