摘　　要： 介绍了辨识理论在发电机励磁系统参数测试中的应用,并以福建古田溪水电厂励磁系统为例,对其参数进行辨识。然后从相位裕度和增益裕度两个方面对辨识结果进行了理论分析。数字仿真结果验证了参数辨识理论应用于励磁系统参数测试的可行性,通过论述和仿真分析,证明了辨识结果是有效可靠的。 The modem power system is coming into an age of big scale, high voltage, and large capacity. The requirement of the generators stability has become more and more important. The excitation system plays a very important role in power system transient stability controlling. It is needed to pay a particular research to the excitation system, and to establish the excitation system model library in the power system simulation software. The operators who in charge of the power network dispatching can use the simulation software with the library to do a precisely stability analyze. This paper expounds the application of identification theory in generator excitation system parameters testing, and briefly illustrates the measurement using this theory for the parameters identification of Gu-Tianxi Power house. Moreover, testing and analyzing the results of identification from phase margin, gain margin and simulating curve. Through the dissertation and simulation analysis, the parameters identification for Gu-Tianxi Power house has been deemed effective and credible. And the application of identification theory for generator excitation system parameters proved feasible.
