摘　　要：电力电子变压器是一种将电力电子变换技术和高频变压器相结合的新型智能变压器,与传统的变压器比,它不仅有隔离、变压和并联运行功能,而且具有灵活控制电压和电流波形变化、改善电力系统电能质量、提高系统稳定性、无功优化以及在输电中与励磁发电机协调控制等功能。根据电力电子变压器的不同运行状况,有相应不同的控制策略,因此在国内外研究成果的基础上,分类和归纳了电力电子变压器的控制策略,分析了不同控制策略的原理、特点及实现方法,为电力电子变压器的研究与应用提供参考。Power electronic transformer is a kind of new intelligent transformer,which is combined power electronic conversion technology with high-frequency transformer,compared with the conventional transformer,it has not only isolation,transformer and parallel operation function,but also has the flexibility to control the voltage and current waveforms change,improving power quality power system,improving system stability,optimizing reactive power and coordinating control of excitation generator in power transmission and so on. According to the different operating conditions of power electronic transformer,the control strategy is different,based on domestic and foreign research results,classified and summarized the control strategy of power electronic transformer,analyzed the principle,characteristics and realization method of different control strategies,and provided reference for the research and application of power electronic transformer.
