摘　　要：风电场中不稳定的电源和负荷波动会导致电力系统稳定性降低。针对静止无功发生器只能补偿无功分量的局限性,设计了静止无功发生器和储能装置并联的优先补偿控制策略。电力系统中负序分量的危害往往大于无功分量和有功分量,为了使储能装置和静止同步补偿器容量利用率最大,在负荷波动时优先对系统中危害最大的负序分量进行补偿。仿真分析表明,通过控制储能装置的充放电方式,系统不但能补偿无功功率,还能有效抑制有功功率的波动,达到了提高系统稳定性的目的。Unstable power sources and load fluctuations in wind farms can lead to a decrease in power system stability.A priority compensation control strategy was designed for the parallel connection of a static reactive power generator and an energy storage device to address the limitation that static reactive power generators can only compensate for reactive power components.The harm of negative sequence components in the power system is often greater than that of reactive and active components.In order to maximize the capacity utilization of energy storage devices and static synchronous compensators,priority is given to compensating for the most harmful negative sequence components in the system during load fluctuations.Simulation analysis shows that by controlling the charging and discharging methods of energy storage devices,the system can not only compensate for reactive power,but also effectively suppress fluctuations in active power,achieving the goal of improving system stability.
