Modeling and Parameter Testing of Governing System for Domestic-Manufactured 700 MW Hydraulic Turbine Suitable to Power System Stability Calculation

By means of on-site measurement of model parameters of a certain governing system for domestic- manufactured 700 MW hydraulic turbine, a governing system model of hydraulic turbine suitable to power system stability calculation is built. Simulation of the built model are performed by power system analysis software package (PSASP) developed by China Electric Power Research Institute (CEPRI); through the examination of the measured model parameters of both prime mover governing system are modified; finally accurate model parameters of the built governing system model for hydraulic turbine suitable to power system stability calculation are given. The built governing system is incorporated into PSD-BPA (GM card) and put into practical application. Application results show that the built governing system model can correctly reflect response characteristics of practical 700MW hydraulic turbines.
