摘要
针对目前获取准确的发电机组参数存在很大难度的问题,提出了一种改进的非线性最小二乘法,即动态测试和稳态测试相结合的两步最小二乘法,对发电机参数进行辨识。仿真研究表明,该方法能够准确地辨识发电机参数,满足工程需要。
Accurate parameters of generating unit are difficult to obtain at present.Therefore,an improved nonlinear least square method,namely the two-step least square method integrating dynamic testing with steady state testing is brought up for identification of generator parameters.The simulation research indicates that the method can accurately identify generator parameters and meet the demand of projects.
