双馈电机超同步运行转子电路复功率的负频率分析法
Rotor Power Analysis of Doubly-Fed Induction Machine During Supersynchronous Speed Using Minus Frequency
摘要
Abstract
There are different ideas whether the rotor frequency of doubly-fed induction machine（DFIM） during supersynchronous speed should be minus or plus.This paper analyses the rotor circuit and proposes that minus frequency is necessary.The feature of minus frequency sinusoidal circuit is researched by means of unified space-time vector and equivalent circuit and applied in rotor power analysis during supersynchronous speed.The rotor reactive power calculated based on the DFIM equivalent circuit might be inductive or capacitive.This character should be judged not only by the sign of reactive power,but also the sign of rotor frequency.A conclusion named ＂reactive power character reverse＂ is obtained.The result of experiment proves that the analysis method and conclusion in this paper are correct.关键词
