着重研究了 STATCOM 接入风电场系统并网点，使变频器与 STATCOM 结合控制，当系统电压在合理范围内变化时， STATCOM 能很好地调节稳定电压，减少向电网输出谐波；当电网发生故障，系统电压跌落严重时，变频器以 STATCOM 模式运行，变频器与 STATCOM 同时向系统发出无功功率，快速稳定系统电压，达到提高风电场低电压穿越能力的目的。

This article in the wind power system and network access can be adjusted continuously and fast response speed of static synchronous compensator (STATCOM), adopt inverter with STATCOM joint control, such that when the grid voltage in the normal range, STATCOM rapidly and stably and network voltage, reduce system to power grid harmonic output; when power system fault cause and network voltage drop is more serious, the inverter operates in static reactive compensation mode, combined with STATCOM network to the output reactive power, improve the stability and voltage and outlets, eventually improve the LVRT capability.
