摘要:
对电力电子变压器(PET)配置保护系统是保证其在工程应用中安全稳定运行的重要措施。文章以 AC-DC-AC 型PET 为例,简单介绍了其输入级、隔离级和输出级通常采用的拓扑结构,包括模块化多电平变流器、双有源桥、三相逆变器等,对其在运行中可能发生的故障进行了归纳,对相应的故障清除及保护技术进行了分析与讨论;然后对配电网中经常发生的故障进行了分类总结,介绍了故障发生时PET 所承受的电应力以及相应的保护配置策略。最后,对PET 故障清除及保护技术方面亟待解决的问题进行了分析,给出了今后的重点研究方向。
Abstract:
Protection system for power electronic transformer is an important measure to ensure its safe and stable operation in engineering application. Firstly, taking AC-DC-AC type power electronic transformer as an example, this paper pointed out its topology structures of input stage, isolation stage and output stage, including modular multilevel converter, dual active bridge and three-phase inverter. Possible faults of the power electronic transformer in operation were summarized, and corresponding fault clearing and protection technologies were analyzed and discussed. Then faults in distribution network were classified and summarized, and electrical stress and corresponding protection configuration of power electronic transformer were pointed out when the fault occurred. Finally, problems to be solved urgently in the field of power electronic transformer fault clearing and protection technologies were analyzed, and future key research topics were proposed.
