Based on the operating principle of MMC, a mathematical switching model applied to the transient analysis of MMC and a mathematical model under dq coordinates of the three-terminal MMC-MTDC system which is suitable for control analysis are derived. 基于MMC的运行工作原理,推导了适用于暂态分析的MMC的开关函数数学模型以及适用于控制分析的三端MMC-MTDC系统dq坐标下的数学模型。
By designing the train-server-monitoring three-terminal mode, the system can monitor several trains at the same time. 此外系统采用了车载-服务器-远程监控终端的三端模式,实现了对多辆列车的同时监控。
Both of the theoretical analysis and simulations are carried out in three-terminal relay system and multi-relay system. 最后在传统的三节点系统和多中继节点系统中,对AF、DF和NAF的性能进行了理论分析和仿真。
