直流励磁发电机组励磁系统参数测试建模及仿真校核

Parameter test modeling and simulating calculation of D.C excitation system for generating unit

通过励磁系统的现场试验,采用电力系统分析综合程序PSASP中的励磁系统模型,得出可用于电网稳定计算的柘溪水电厂6号发电机组励磁系统的实测模型和参数。文章总结了使用PSASP进行励磁系统参数仿真的步骤,并给出试验数据与仿真数据的对比结果,结果验证了上述方法的正确性和实用性。

By excitation system field test, excitation model in power system analysis software package PSASP is used to gain practical model and parameters for power grid stability calculation of No. 6 generator excitation system in Zhexi hydro power station. The steps of excitation system modeling by using PSASP were presented. Test data were compared with simulated data and the results indicate that the modeling method were correct and practical.
