以电力电子器件控制作为实现手段 ,分析了双三点式静止无功发生器 ( SVG)逆变电源实现无功功率控制的工作原理 ,并根据等效电源与系统电源之间的相角差以及它们与系统输入无功之间的对应关系 ,提出了电压内嵌式无功功率同步控制的基本思想 ,它不但可以有效实现无功功率的控制 ,同时还可以稳定节点电压。文中给出了双三点桥式逆变电源在不同情况下各有关电量的仿真曲线。 Based on the control of power electronic devices, the working principle of reactive power control of dual three-point SVG inverter is analyzed. Based on the phase difference between the equivalent power supply and the system power supply, The system inputs the corresponding relationship between the reactive power, and puts forward the basic idea of ​​voltage embedded reactive power synchronization control, which not only can effectively control the reactive power, but also can stabilize the node voltage. The article gives the simulation curve of the power consumption of the double three-point bridge inverter in different situations.
