摘要
风能的快速发展及其与现有电网的整合可能会导致电能质量问题。因此，本文试图解决感应发电机作为并网感应发电机(GCIG)和自励感应发电机(SEIG)运行时的主要电能质量问题。为GCIG和SEIG运行开发的MATLA B SIMULINK模型对分析这些影响很有用。利用对这些感应发电机的仿真结果，确定了影响有功功率、无功功率、总谐波失真等电能质量问题的电机参数。进一步分析GCIG和SEIG两种工作模式下的模拟结果，对提高发电机整体电能质量的设计有一定的指导意义。
Power Quality Issues of Induction Generators in Different Operating Modes
Fast wind energy developments and their integration in existing power network may result in power quality problems. Therefore, in this paper, an attempt has been made to tackle the major power quality issues related to induction generators operating as grid connected induction (GCIG) and self excited induction generator (SEIG). MATLA B SIMULINK models as developed for GCIG and SEIG operation are found to be useful to analyse these effects. Simu lated results as obtained on these induction generators have been used to identify the machine parameters affecting the power quality issues such as active & reactive power, total harmonic d istortion etc. Further analysis of simulated results for two operating modes i.e. GCIG and SEIG seems to be useful fo r the design of such generators for overall power quality improvements.
