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

通过现场实测某700MW水轮机调节系统模型参数,建立了适用于电力系统稳定计算用的水轮机调节系统模型。用电力系统分析综合程序对该模型进行了仿真,对实测的原动机及调节系统模型参数进行了校核,最终给出了电力系统稳定计算用水轮机调节系统模型准确参数。此模型已经编入电力系统稳定计算程序(PSD-BPA)并投入使用。结果表明,该模型能反映实际现场设备响应特性。

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.
