SVG 工作原理 Working principle

静止无功发生器（SVG）通过外部电流互感器（CT），实时检测负载电流，并通过内部 DSP 计算来分析负载电流的无功含量，然后根据设置值来控制 PWM 信号发生器发出控制信号给内部 IGBT 使逆变器产生满足要求的无功补偿电流，终实现动态无功补偿的目的。 

Static Var Generator (SVG) detects the load current in real time through external current transformer (CT), analyzes the reactive power content of the load current through internal DSP calculation, and then controls PWM signal generator to send control signals to internal IGBT to enable inverter to generate reactive power compensation current meeting the requirements according to the set value, finally realizing the purpose of dynamic reactive power compensation.
