Evaluating the transient performance of standby diesel-generator units by simulation

The transient behavior of the standby diesel-generator units and the engineered safeguard loads at an operating nuclear power generating station was simulated using the electromagnetic transients program (EMTP). The authors discuss the standby diesel-generator units and the engineered safeguard load model development and the validation and verification of the applicable EMTP modules. The simulation results demonstrating the standby diesel-generator unit capability and illustrating the predicted transient deviations in the generator terminal voltage and frequency are included together with the voltage deviations within the engineered safeguard features distribution system.<
