| Abstract:With the development of power grid technology, the problem of loss in distribution network circuit becomes more and more obvious. For the line loss, this paper proposes the application of UPFC to reduce the distribution network loss. This paper uses UPFC to 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 in this paper, 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. Through experiments, the method designed in this paper 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. |
