摘要
为了解决传统分布式控制架构中光纤和光模块用量大、安装布线复杂以及PEBB间不同步的问题,将无源光纤网络系统的思想应用于MMC控制系统架构的设计,提出了基于光分路器的MMC分布式控制系统架构。新型控制架构由主控制器、PEBB和光分路器组成。主控制器与每个相单元所有PEBB控制器之间通过两个光分路器连接,一个光分路器用于传输主控制器发送至PEBB控制器的下行信号,另一个光分路器用于传输PEBB控制器发送至主控制器的上行信号。实验与仿真结果表明,基于光分路器的MMC分布式控制系统架构可以大大减少光纤和光模块使用量并保证PEBB之间的同步,使MMC系统正常运行。
In order to solve the problem of large consumption of fiber and optical module, complicated installation and PEBB’s non-synchronization in traditional distributed control architecture, the idea of passive optical network system was applied to the design of MMC system control architecture, and a MMC distributed control system architecture based on optical splitter was proposed. The new control architecture consists of a master controller, PEBBs and optical splitters. The master controller and all PEBB’s controllers of each phase unit are connected by two optical splitters. One optical splitter is used to transmit the downlink signal sent by the master controller to the PEBB’s controller, and the other optical splitter is used to transmit the uplink signal sent by the PEBB’s controller to the master controller. The experiment and simulation results show that the new control architecture can greatly reduce the consumption of fiber and optical module, and ensure the synchronization between PEBBs, so that MMC can run normally.
