基于磁链观测器的定子频率算法研究
The stator frequency algorithms based on the flux observer
摘要
Abstract
Two major defects of solving the stator side frequency via traditional stator side flux observer in the doubly-fed wind power generation system are presented. According to that, three improved frequency algorithms, such as the restricting Ua algorithm, the voltage differential coupled algorithm and the areeosine function algorithm are proposed. Furthermore, the performances of the three kinds of the improved algorithms are compared by theoretical and numerical methods. It is showed that the arceosinefunction algorithm is the best optimal one.关键词
