Simulation of the Dynamic Performance of a PWR Plant as a Power Supply in a Large Power System

This work aims at modeling, simulating and analyzing the dynamic performance of the first egyptian pressurized water reactor nuclear power plant as a power supply in a forecasted national power system. A digital simulator has been developed which incorporates nonlinear mathematical models for: a PWR, pressurizer, steam generator, coolant pumps, steam and hydro-turbines, synchronous machines, loads and other network components, plant controllers and speed governors. The results obtained include: 1. The dynamic response of the nuclear plant following the forced outage of two of the feeding Transmission Lines (T.L´s.), i.e. 21 % loss of the area power supply. 2. The overall system frequency behaviour following the disconnection of the PWR plant. 3. A comparison between Dynamic Energy Balance (DEB) frequency calculations of the overall power system (represented by its center of inertia) and the transient stability calculations of the nuclear plant system frequency following the loss of 28 % of the area power supply.
