Abstract

Abstract: The high-order mathematical model of nuclear power units is with complex structures, and is not suitable for applications because of massive and time-consuming simulation calculations. But the reduced mathematical model can be only used for the short-term stability analysis. So it is necessary to establish a mathematical model of the nuclear power units suitable for the mediumand long-term stability analysis of power systems. The mathematical model of the pressurized water reactor(PWR) nuclear power unit is hereby established. Based on this model, the inherent characteristics of the nuclear power unit have been analyzed. By the simulation of a single machine infinite bus(SMIB) system, the interaction between the nuclear power unit and the power system is also studied. As long as the fault is removed timely, there will be no great impact on the nuclear power units.

Key words: PWR, nuclear power units, mathematical model
