基于并行冗余协议的高可靠性过程总线通信研究
Highly Reliable Process Bus Communication Parallel Based on Redundancy Protocol
摘要
Abstract
To guarantee the lossless transmission of sampled measured values and trip signals,a parallel redundancy protocol（PRP） is used to implement the high reliability process bus.The architecture and the running mechanism of PRP based transformer differential protection are analyzed.A transmission rate of sampled values based method used to calculate the time of fault location is proposed.According to the distributed relay protection logic function,four popular architectures of protection systems and their reliability block diagram are created.Considering the influence of joint events in minimal cuts which may involve very complicated calculations by using the direct disjoint form calculation method,a simplified compensation algorithms based on minimal cuts is adopted to calculate and analyze the system reliability.The calculation result indicates the high-reliability advantage of the application of PRP based process bus solution.关键词
