摘要
提出了利用现有的设备(软启动逆变器)来抑制分布式发电系统中微型燃气轮发电机谐波电流的方法,并详细给出其拓扑结构,谐波电流检测方法及滞环控制策略。仿真结果表明:所设计的拓扑结构和采用的控制方法是可行的,完全消除了5次和7次谐波电流。
In this paper, a method of using an existing device （start-up inverter） in a given topology of a distributed power system to lower harmonic current in high speed generator （HSG） is presented. The method presented is introduced in detail in the paper. The measuring and calculating method for harmonic current and the harmonic current-based hysteresis control strategy of the active power filter （APF） using start-up inverter are proposed. The simulation results show the feasibility of the proposed structure and the control strategy. The 5th and 7th harmonic currents of generator current are eliminated completely.
