Analysis of Risk Factors for Harmonic Voltage Distortion Caused by Inrush Current

Abstract:

With the power grids gradually extending to remote areas, the number of the connection line with long distance, light load are increasing. In such a grid, the closing operation of the unloaded transformer may cause severe voltage distortion in the end of system due to the inrush current. This paper analyzes the risk factors for harmonic voltage distortion caused by the inrush current with two methods, including indexes comparison and simulation research. It is showed that the different generators operation modes and load levels have major impact on the risk for voltage harmonic distortion caused by inrush current in the system, and these factors need to be carefully considered in the analysis.
