In order to meet the need of start debugging with a new 500kV line of site power transmission engineering system, uses PSCAD analysis software to analyze and calculate the power frequency overvoltage, switching overvoltage, secondary arc current and recovery voltage forl soon put into production of the project. The results are related to the settlement procedures to meet the requirements, and to ensure that the system works in the field to start the debugging process to determine the safety and overvoltage protection configuration and reclosing time to provide a theoretical basis, provide a reference for operation. Overvoltage calculation of similar projects within the project also provides overvoltage reference for the calculation.
