摘　　要：异步化同步发电机(ASG)能提高系统的稳定性,当其与同步发电机并联运行时,联合系统的状态方程必须建立在同一坐标轴下。该文首次建立了同步坐标轴下异步化同步发电机与同步发电机并联运行时的状态方程,并对所建立的状态方程使用分散变结构控制的方法进行了励磁控制器的设计,仿真结果表明该方法有较好的动态响应,能提高系统的稳定性。Asynchronized Synchronous Generator (ASG) can enhance power system's stability. When it paralleled with synchronous generator,the whole system's state space equations must be set up in the same coordinate.This paper sets up the parallel system's state space equations in the synchronized coordinate for the first time.And decentralized variable structure control was used for designing the excitation controller.This method was applied to Asynchronized Synchronous Generator paralleled with synchronous generator connected with infmite bus.The simulation results show this method has good dynamic response and the designed excitation controller can improve the power system's stability.
