摘　　要：给出了测试和计算渭河3号机组励磁系统参数的方法,总结了使用电力系统综合仿真分析程序PSASP进行空载阶跃仿真计算的步骤,并调整了仿真计算中的参数,得出了PSASP使用的励磁调节器的计算模型和参数,指出了励磁系统参数回归中应注意的问题。根据现场实测数据,得到了可用于电网稳定计算的渭河电厂3号机组励磁系统的实测模型和参数,仿真实验验证了上述方法的正确性和实用性。The method for parameter measurement, testing and calculation for excitation system of No. 3 unit in Weihe power plant is given; the procedures of applying power system analysis software package （PSASP） in no-load step simulation are presented, the parameter is adjusted during the simulation, thus the calculation model and parameters of excitation regulator used in PSASP are obtained. The problems, which should be paid attention to during the simulation, are pointed out. According to the on-site measured data the measured model and parameters of excitation system of No. 3 unit in Weihe power plant that can be used in power grid stability analysis are achieved. Simulation results show that the presented method is correct and practicable.
