Research on Lightning Protection of 220kV Substation with Long Cable Inlet Wire
2021 6th Asia Conference on Power and Electrical Engineering (ACPEE)(2021)
Abstract
Lightning protection of urban power grids is critical to the safe and stable use of electricity in cities. In the paper, the electromagnetic transient program (EMTP) was used to simulate the lightning protection of a 220kV substation reconstruction project with long cable inlet wire. Using the intersection method, the maximum value of the lightning invasion overvoltage on the substation equipment ...
