Abstract:On-site investigation and testing of excitation system models and governor (including prime mover) system models of typical turbo-generators, whose rated capacities are 200MW and higher, and water turbo-generators, whose rated capacities are 100MW and higher, in Central China Power Grid and Sichuan-Chongqing Power Grid and parameters of these models are carried out. The experiences of on-site testing of parameters of generator excitation system are summarized. According to the results of on-site investigation and testing the mathematical models of generator excitation system and governor system as well as the model parameters, which can be adopted in power grid stability analysis, are determined. The methods to judge and verify the correctness of both mathematical models and parameters obtained by on-site testing are proposed, so that the correctness of both models and parameters can be ensured. In order to guide real production, these models and parameters are utilized in daily dynamic security analysis and some achievements are gained.
Keywords:generator  excitation system  governor system  parameter testing  power system stability analysis
