摘　　要：针对在煤矿井下电网的电能质量治理中,有源电力滤波器等隔爆型开关补偿设备工作在煤矿井下巷道空间狭窄等特殊性环境中,其体积(容量)受到限制的问题,为了提高开关补偿设备的补偿特性,结合CPT(Conservative Power Theory)功率理论,提出了一种体积(容量)受限时的参考电流计算的新方法。该方法将负载电流分解后的正交的电流分量或其组合作为隔爆型井下补偿装置的参考电流,可以依据电网的实际情况实现不同的补偿目标。仿真验证了该方法的可行性。As in the severe underground environment,the size of the switching compensator devices is limited,to improve the response speed and compensation effect of switching compensator device,a new strategy for reference current calculation is presented based on Conservative Power Theory.Through the orthogonal decomposition of the load current by the strategy,the reference current of various compensation objectives for switching compensation devices can be calculated by the current components or their combinations.It is demonstrated that,this strategy can be used for various goals of flame-proof type switching compensation devices.The validity of the developed strategy is verified by the simulation results.
