CIGRE HVDC控制器的PI可视整定方法
A Tuning Method of PI Parameters Based on Visualization for CIGRE HVDC Controller
摘要
Abstract
Considering the lack of the current method of PI regulator, which requires repeated trial and error and is not easy to be obtained, a tuning method of PI parameters of visualization is given in this paper. The proposed method is achieved by plotting the stability boundary locus directly based on system model in the (Kp,Ki )-plane and determining the stable region also called stable set. Then, by using the required frequency-domain performance index, the parameters that meet the frequency-domain performance index can be obtained in the stable set and meanwhile drawn it out in the region. Finally, on the base of the frequency-domain parameters optimization, the best set of PI tuning parameters satisfying the time-domain performance indexes which including the steady-state performance index ,the dynamic performance indexes and the rise time can be found. The simulation of CIGRE HVDC Benchmark model shows the validity of the method approached.关键词
