Year: 2025
Type: conference-paper
Abstract: The normal operation reliable power supply system of a nuclear power plant is equipped with a diesel engine power supply, in which the wiring is complicated and the operation modes are numerous. Therefore, in addition to the basic settings according to the standards, the relay protection settings of the power plant also need to be configured based on actual operating conditions, especially the grounding protection setting, contradicting the previous habit of protective design. This paper analyzes and calculates the protection settings of diesel engines and the coordination of the upper and lower reaches of the diesel engine. The protection configuration of the normal power supply line, the standby power supply line, and the bus connection switch are determined.
