摘　　要：风电光伏等新能源行业的大量并网非线性负荷和冲击性负荷的广泛应用,带来了严重的电能质量问题,功率因数低,电网电压波动及闪变等。本文从治理电网质量的角度,介绍了新风光SVG系列产品的特点,将自换相桥式电路通过变压器或者电抗器并联在电网上,适当地调节桥式电路交流侧输出电压的幅值和相位,或者直接控制其交流侧电流就可以使该电路吸收或者发出满足要求的无功电流,实现动态无功补偿的目的。The extensive application of grid-connected non-linear load and impact load in wind,solar and other new energy industry has brought serious power quality problems,such as low power factor,voltage fluctuation and flicker.In this paper,the characteristics of the SvG series of Xinfengguang are introduced from the point of view of improving the quality of power network,by adjusting the amplitude and phase of the output voltage on the AC side of the bridge circuit properly,or directly controlling the current on the AC side of the bridge circuit,the circuit can absorb or emit the required reactive current,the aim of dynamic reactive power compensation is realized.
