电网电压不平衡度对 DFIG 运行特性的影响
Influence of the unbalanced grid voltage on operational characteristics of DFIG
摘要
Abstract
Based on the analysis of the unbalanced grid voltage theory and common presentation of voltage unbalance , the out-put power of doubly fed induction generator (DIFG) is deduced, and the operating characteristics of DFIG is studied during unbalanced grid voltage .For the further research on the operating characteristics of DFIG , and the con-nection grid model of the DFIG is built in Matlab/Simulink .Results have shown that , with the increasing degree of the unbalance , the output pulsation amplitude of active and reactive of the DFIG and stator-side and rotor-side, in-crease almost linearly .In the same unbalance degree , active pulsation amplitude is higher than the reactive power pulsation amplitude .关键词
