SVG 由自换相电力半导体桥式变流器来进行动态实时无功补偿，是目前较为先进的无功补偿方式，它不再采用传统无源大容量电力电容器作为无功补偿来源，而是通过大功率电力电子高频开关，实现无功能量的转换，从而使无功补偿技术产生质的飞跃。同时具备快速动态响应、更高安全性能、更高补偿精度、更多样化补偿功能、极低补偿后谐波含量、更小巧产品体积、更便利增容方案。并且还可以实现 APF(有源滤波)功能，该产品可以滤除2~13 次配电系统谐波，综合解决配电系统中所需解决的无功补偿、谐波电能质量、三相负载不平衡等问题。

SVG carries out dynamic real-ime reactive power compensationby self-commutating power semiconduclor bridge converter, whichis a relalively advanced reactive power compensation method atpresent.lt no longer uses traditional passive large-capacity powercapacifors as the source of reactive power compensalion, bulrealizes the conversion of non-functional quantities through high-power electronic high-frequency switches, thus making a qualtativeleap in reactive power compensation technology. At the same time.it has fast dynamic response, higher salety perlormance, higher compensalion accuracy, more diversified compensafion funcfionsexlremely low harmonic confent after compensalion, smaller productvolume, and more convenient copacily expansion scheme. And ilcan also realize the APF(active filter) function, the product can filterout 2 -13 harmonics of the distribution system, and comprehensivelysolve the reactive power compensation, harmonic power quality,three-phase load imbalance and other problems needed to besolved in the distribution system.
