摘　　要：研究接入点电网电压波动下风电机组储能变流器的控制策略,以提高其应对接入点电网电压波动情况下的应变能力.根据三相电路瞬时功率理论实现储能变换器的有功和无功功率的解耦控制.仿真和实验结果表明,在电网电压发生波动时,储能变流器能给电网提供无功支撑,支持其快速恢复.The control strategy of wind power generator energy storage converter under voltage fluctuations is studied to enhance the capability when the access point voltage fluctuate. Energy storage converter decoupling control of active and reactive power could be achieved through the three-phase instantaneous reactive power theory. Simulation results showed that under voltage fluctuation the energy storage converter could support reactive power and accelerate the power grid recovery to normal rapidly.
