适用于多种子模块拓扑的MMC通用化快速仿真模型
|
摘要
针对现有模块化多电平换流器(MMC)快速仿真模型通用性差的问题,提出了一种适用于多种子模块拓扑的MMC通用化快速仿真模型。结合子模块的结构特征,构建了MMC桥臂闭锁结构,并将闭锁结构分为三大类。通过构建不同子模块拓扑的MMC的简化表,避免了因子模块拓扑的不同而需修改模型自定义程序的问题,增强了模型的通用性。所构建的闭锁结构既保证了通用化快速仿真模型在正常与闭锁运行等各种工况下的适用性,又使得同一类闭锁结构可适用于多种子模块拓扑的MMC,增强了闭锁结构的通用性。在PSCAD/EMTDC仿真软件中通过与详细模型进行对比,验证了通用化快速仿真模型的有效性和可行性。
To address the poor generality issue of existing fast simulation models of MMC(Modular Multilevel Converter),a general fast simulation model of MMC that considers multiple SM(Sub-Module) topologies is proposed. According to the structure features of SM,an arm blocking structure of MMC is established,and is further divided into three categories. The simplified tables are constructed for MMC with different SM topologies,which can avoid the problem that the user programs need to be modified owing to different SM topologies. As a result,the generality of the model can be enhanced. The proposed blocking structure not only ensures the applicability of the general fast simulation model under various operating conditions including normal and blocking states,but also enables a same type of blocking structure suitable for the MMC with multiple SM topologies,and the generality requirement of blocking structure can be satisfied. The effectiveness and feasibility of the proposed general fast simulation model are verified by comparison results with a detailed model on PSCAD/EMTDC.
