异步电机饱和漏抗的辨识

本文运用现代控制理论的系统辨识方法,对所建立的异步电机数学模型中的不易测出的漏抗参数值进行拟合求解,提供了确定异步电机漏抗参数的又一种方法。从理论上和方法上分析,这样算得的结果要精确于用常规实验所测取的值。最后,利用所得到的参数进行瞬态仿真运算求解,得到的结果与瞬态实测值相符合。

Identification of the Saturated Leakage Reactance of Asynchronous Machines

By means of modern control theory, the state and parameters of proposed model are estimated by a filter algorithm in the thesis. It is possible to estimate the leakage reactance parameters by rising those methods, but it is difficult to measure them directly. So another method used to determine the leakage reactance of induction machine is provided, the results thus calculated of the model are more exact than general experimental results.Taking the obtained parameters into the model, it has been found that the response of the model basically fits transient experimental result.
