Modeling and parameter measurement research pressurized water reactor nuclear power generator´s prime mover and governor

Domestic nuclear power plants generally bear base load, electrical power network less demanding its performance of coordination between the source and power grid, simulation analysis model for pressurized water reactor nuclear power plant and generator\´s prime mover and governor is also lagging behind. With the rise in domestic PWR nuclear power capacity, it is necessary for PWR nuclear power plant simulation model and its prime mover and governor system for precise adjustment of the study, further analysis of their interaction with the grid, improving the performance of its network source coordination. Based on the " Guide for Modeling and Testing of Generator\´s Prime Mover and Governor" requirements, the actual modeling for Ningde Nuclear Power Station Unit 1, the test content for governing system of nuclear power, actuator, prime mover and energy supply system, etc. And nuclear power plant load test. Parameters measured for governing systems and actuator, using mathematical models to build Matlab simulation parameters were checked, and the use of PSD-BPA measured parameters for the prime mover and energy supply system were recognized. According to the measured parameter identification, the use of PSD-BPA measured data for the load test Ningde Nuclear Power Unit 1 of the simulation verification, simulation results and experimental data to meet the "Guide for Modeling and Testing of Generator\´s Prime Mover and Governor" requirements. The simulation results can truly reflect the dynamic load characteristics of the PWR nuclear power plant for power system stability provides a mathematical model and parameter calculation can be used to schedule the security and stability analysis.
