摘　　要：提出一种基于多目标控制的调控装置,用于电力系统的动态无功补偿、谐波抑制和短路限流。基于三相背靠背变流器及相关多目标控制技术,对负载和限流电抗器进行无功补偿和谐波抑制,在系统发生短路故障时,应用限流电抗器抑制短路电流。应用EMTDC/PSCAD仿真软件对该控制策略进行了仿真,并通过实验验证了该控制的理论原理,该装置已在实际工程中得到良好应用。This paper puts forward a multi-objective control which applied in parallel back-to-back convertor,which compensates the harmonics and reactive power and increases the voltage on the load side, aimed at reducing voltage sag caused by reactors, harmonics and reactive power in power system.The corresponding simulation research is taken on EMTDC/PSCAD platform,the results verify the theory of each control strategy.At last, some experimental waveforms prove the theory is right,this device is applied on the power system, it is proved that this device can solve actual problems occurred on power system.
