摘　　要：针对传统三相感应发电机定子电流耦合复杂和控制困难的问题,研究了一种新型的定子双绕组感应发电机,使该新型发电机的两套定子绕组上分别通过系统的有功电流和无功电流,实现解耦控制。利用MATLAB对定子双绕组感应发电系统在变转速和变负载(纯阻性负载)的工作情况下进行系统容量的仿真研究,得出了两套绕组的容量比规律;同时得出了相同参数和工作条件下的定子双绕组感应发电机系统的控制绕组电流仅为传统三相感应发电机系统定子绕组电流的0．57 倍。仿真结果表明,定子双绕组感应发电机系统不论在控制和实际应用上都具有传统三相感应发电机系统不可比拟的优点,因此这种探索性研究具有重要意义。It is difficult that the conventional induction generator is accurately controlled. The novel dual stator -winding induction generator is studied in this paper. The decoupling control is realized in the dual stator-winding induction generator through making active current and reactive current flow through two sets of stator windings The simulation of dual stator - winding induction variable load is studied in Matlab, the rule of capacity ratio generator system under variable stator speed and of two sets of stator windings is summarized. At the same time, the comparison of the dual stator - winding induction generator system with conventional induc- tion generator system is done in the same work condition, the result is obtained, that control winding＇s current is 0. 57 times of stator winding＇ s current of conventional induction generator. All these results indicate that it is significative to study the dual stator- winding induction generator system.
