| 摘 要： | 为了提高静止同步补偿器控制的稳态与动态性能,探讨在静止同步补偿器(STATCOM)的数学模型基础上,采用单周控制与开关电路相结合的控制方法.该方法不需要检测系统的无功电流,直接以补偿最终要达到的电压目的来控制开关管在每个周期内的占空比.仿真实验结果表明了该控制方法能够确保系统对负载在一定范围内变化时具有较强的鲁棒性,使系统能够快速补偿电网无功功率.

| Abstract: | In order to improve the stable state and the dynamic performance of STATCOM,based on the mathematics model of STATCOM,this paper presented a control method combining one-cycle control and switch circuit together.This method compensated the specified power by controlling the dutycycle of switch tube in every cycle instead of measuring the reactive current of system.Simulation results verified that the proposed method could not only make the system robust but also compensate the reactive power rapidly when th... |
