【摘要】 利用新型电源12相发电机精确的数学模型,得到其离散状态空间方程,在此基础上,应用扩展卡尔曼滤波算法首次实现了其定子参数辨识。利用PSCAD和MATLAB软件分别实现了电机的仿真与辨识;辨识程序分无噪声和有噪声2种情况,且2种情况辨识结果误差均控制在9%以内,证明了此方法的有效性。更多还原

【Abstract】 By the mathematical model of a new power supply:12 phase generator,its discrete-time state space equation was obtained,and by application of EKF,12 phase generator stator parameters identification was achieved.Using PSCAD and MATLAB software,simulation and identification of the generator was implemented.Under the two conditions of noise-free and noise,the results indicate the effectivity of the method.更多还原
