摘　　要：随着电网规模的不断扩大和电压等级的不断提高,对机组运行稳定性的要求也随之提高,更为精确详细的励磁系统模型有助于电力系统的稳定性分析。本文基于MATLAB利用时域分段线性法(PLPF法)对励磁系统参数进行了辨识,并验证了辨识结果的正确性。With the enlargement of the power net and the improvement of the voltage rating, the requirement of the generator stability becomes more and more exigent. Accurate and sufficient excitation system models are essential to stability analysis of power system. Based on MATLAB, the parameters of excitation system are identified by PLPF method, and the correctness of the results is verified.
