Research on the Method of Optimizing Distribution Network Loss by Using UPFC

For the line loss,the application of UPFC to reduce the distribution network loss is proposed.using UPFC accurately control the power flow distribution and improve the power flow distribution of transmission lines.It effectively reduces the line loss caused by the three-phase unbalance,improves the line transmission capacity,and enhances the reliability of the power grid,a new three-phase power compensation circuit is added to the UPFC device,which can automatically collect the voltage signal and current signal in the grid circuit,and calculate the collected voltage and current signal.The calculated signal information is generated by the control circuit to generate a driving signal,and the driving information is transmitted to the main circuit.The main circuit performs current compensation on the power grid according to the driving signal,and the computer controls the operation process and displays the control result.The experiments show the method designed significantly reduces the loss in the grid circuit,increases the use of active power,and provides a good environment for the stable operation of the grid circuit.
