摘　　要：为提高变压器的运行效率,提出一种基于电力电子换流器的变压器经济运行管控技术,通过有效治理负载中的无功电流、谐波电流及三相不平衡电流,对变压器进行经济运行管控,最终提高变压器的运行效率。经过对电力电子换流器的拓扑和控制方法的研究,搭建了系统仿真模型,完成了仿真论证。结果表明,提出的电力电子换流器及控制方法,可实现对变压器的经济运行管控,最终提高变压器的运行效率。To improve the operating efficiency of transformers,this paper proposes an economical operation and control technology of transformers based on power electronic converter,which can control the economic operation of transformers by effectively controlling reactive current,harmonic current and three-phase unbalanced current of the load,and finally improve the operating efficiency of transformers.After the study of the topology and control methods of power electronic converters,a system simulation model is built and the simulation demonstration is completed.The experimental results show that the power electronic converter and control method proposed in this paper can realize the economic operation and control of transformers and ultimately improve the operating efficiency of transformers.
