摘要
电力电子变压器在兼备传统电力变压器的同时,具有优化配置各种电源、改善供电质量、控制功率潮流和提高系统稳定性等功能,是未来配电网实现电力变换与控制的主要载体之一。介绍了电力电子变压器的工作原理、拓扑结构、控制策略,并结合未来智能配电网对电力变换与控制的需求,对电力电子变压器的发展进行了展望。
While having the functions of the conventional power transformer, the power electronic transformer( PET) can perform optimal configurations of various power supply, improve power quality, control power flow, and enhance the stability of the system, etc. Thus, it will be one of the main equipment for power conversion and control of the distribution network in the future. This paper introduces the working principle, topology structure and control strategy of the power electronic trans-former. Finally, the future development of power electronic transformers is prospected based on the needs of power conversion and control for the smart distribution network.
