MMC-UPQC在RTDS仿真中的脉冲输入方案设计

统一电能质量控制器（UPQC）装置投入现场运行之前，开展基于实时数字仿真器（RTDS）的实验是非常重要的一步，不仅能够使UPQC控制器的功能和性能得到较为充分的验证，还可以积累经验为后续的物理实验提供重要的指导和借鉴。基于模块化多电平换流器（MMC）结构的UPQC由于模块数较多，需要触发的IGBT很多，为了合理利用RTDS宝贵的资源，在开展RTDS实验的时候，必须要对资源分配进行优化设计，其中脉冲的输入方案就是其中的一个重要环节。论文在分析说明MMC-UPQC的拓扑结构的基础之上，首先对RTDS及UPQC的物理控制器的结构和需求进行了梳理和分析，然后给出了两种脉冲输入方案并进行了对比分析，最后在RTDS平台上进行了数字-物理闭环仿真实验，实验结果验证了所给脉冲编码方案的可行性。

Pulse input scheme design of MMC-UPQC in RTDS simulation

Before the UPQC device put into operation, carry out the RTDS test is a very important step, can make the device fully validated MMC structure based on UPQC module as the number of many triggered IGBT, RTDS in order to make rational use of valuable resources, when carrying out the RTDS experiment, we must optimize the design of resource allocation among them, the pulse input scheme is one of the important links. This paper based on describing the topology structure of MMC-UPQC on the first physical controller of RTDS and UPQC structure and demand were sorted and analyzed, and then gives the pulse input scheme two and analyzed, finally, in the RTDS simulation to verify the feasibility of the given.
