MMC-UPQC在RTDS仿真中的脉冲输入方案设计
|
摘要
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。文章在分析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平台上开展了数字-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。
Before the UPQC device puts into operation,carrying out the RTDS test is a very important step,which can make the device fully validated MMC structure based on UPQC module as the number of many triggered IGBT,but also the experience can be accumulated to provide important guidance and reference for the sequent physical experiments.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,and the pulse input scheme is one of the important links. Based on describing the topology structure of MMC-UPQC,the physical controller of RTDS and UPQC structure and demand were firstly sorted and analyzed,and then,two kinds of pulse input schemes were compared and analyzed. Finally,the experimental results verify the feasibility of the proposed pulse coding scheme through the digital-physical closed-loop simulation experiment carried out in the RTDS platform.
