摘　　要： 针对常规电路级均流分析方法存在实现方式复杂、需要增加装置的不足,本文从场的角度出发,提出了一种物理级均流分析方法。该方法直接使用实物模型仿真,综合分析多物理场间的耦合作用,得到更加真实的均流分析结果。以大容量晶闸管并联实物模型为例,叙述了并联均流的物理级建模和仿真过程,在此基础上对均流母线的结构进行了改造,通过双排布置和不均匀分布两种措施显著提高了均流效果。 Conventional analysis and improvement method of parallel current sharing have disadvantages of being complex and needing additional equipments. From the view of field theory, a physical-level current sharing analysis method is developed. In this paper, a practical physical model has been used to simulate parallel current sharing, and whose coupling purpose is comprehensive analyzed at the same time. So, more actual results of current sharing analysis are achieved using this method. High power thyristors in paralleling are considered, then physical-level modeling and simulation process are introduced comprehensively. On this basis, the bus structure is adjusted, and current sharing effects have been improved evidently through double-line and uneven arrangement.
