Research on Reactive Power Compensation Technology of Power Supply System Based on SVG
To reduce the losses of power supply lines and transformers,and improve voltage stability,based on the analysis of the principle and chain structure of SVG,a composite control strategy of SVG based on PI control and repetitive control is proposed.Then,a closed-loop loop is connected to achieve real-time tracking of SVG compensation and harmonic current.The simulation results show that when inductive load is added to the main circuit,there are large reactive power and negative sequence current in the circuit.When SVG compensation is combined with compound control,the voltage is stable,the circulation of the power side and the load side is close to 0,the compensation effect is good,and the instantaneous response speed is fast.
