摘　　要：在分布式发电及微电网领域,随着系统容量和电压等级的不断提高,采用三电平拓扑结构的DC/DC和AC/DC变换器得到大量的应用,但是在国内外一直没有实现其试验方法的标准化。本文以三电平DC/DC和AC/DC变换器的基本试验方法为研究对象,结合多种应用场景,在充分考虑现有国内外测试技术规范的基础上,重点从并联试验、功率控制试验、电网电压或频率异常响应试验等方面展开研究,并提出可行性试验方案。In the field of distributed generation and microgrid, with the continuous improvement of the system capacity and voltage grade, the DC/DC and AC/DC converters with three-level topologies are widely used, but the standardization of the test methods has not been achieved both at home and abroad. Taking the basic testing methods of three-level DC/DC and AC/DC converters as the research object, combining with various application scenarios and in full consideration of the existing domestic and international technical specifications for test, this paper focuses on the parallel test, power control test, grid voltage or frequency abnormal response test and other aspects of the study, and puts forward a feasibility test program.
