Study on the faults of nuclear power plant and effects on transient stability of power system

In this paper the software PCTRAN simulate the new generation of nuclear power plant for the Westinghouse AP1000 accident. Such as the nuclear power plants breaks down, the normal full power operation of the coolant pump rotor for death, loss of feed water, turbine trip and break loss of coolant (LOCA). When a serious nuclear power plant failure occurs, it will result in load rejection of nuclear power. With the electric power system integrated simulation software (PSASP) analyses the nuclear power plant will impact load rejection of the power grid transient stability and suggest measures to improve the power grid frequency and voltage.
