SVG 工作原理 Working principle

靜止無功發(fā)生器（SVG）通過外部電流互感器（CT），實時檢測負載電流，并通過內(nèi)部 DSP 計算來分析負載電流的無功含量，然后根據(jù)設置值來控制 PWM 信號發(fā)生器發(fā)出控制信號給內(nèi)部 IGBT 使逆變器產(chǎn)生滿足要求的無功補償電流，最終實現(xiàn)動態(tài)無功補償?shù)哪康摹?nbsp;

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.
