High Speed and Intelligent Communication Topology Dedicated to Complex Power Electronic System Integration

The universal control structure used for digital power system does not fully utilize merit of digital communication. For power electronic application with requirements of high system complexity and high power, distributed communication structure is the developing trend of system integration. A novel intelligent communication topology with high speed for PEBB is presented. The prominent characteristic of the very structure is that data source for every communicating unit can be determined by its current state. Propagation delay is reduced and transmitting speed is improved. The topology fits to be adopted in complex power system, contributing to distributed control and integrated management for the power system. Compared with the original communication topology, it is more suitable for real time response system. The synchronous problem introduced by original communication topology can be eliminated. The very structure also reduces cost for fiber net Experimental waveforms are presented and propagation delay between two adjacent nodes is obtained. According to capacity calculation, the very control system adapts to power electronic converter with high switching frequency as well.
