Abstract

IEC 62439 defines the parallel redundancy protocol (PRP) which offers zero disruption time for network communication. This paper evaluates the reliability of PRP based substation process bus considering protection functions. Two typical process bus solutions are discussed for a typical transmission substation. To reduce the calculation complicity, the approximation algorithm of reliability evaluation is presented based on the direct disjoint algorithm of the minimal cut sets. An example for the bus protection is given to demonstrate the approximation algorithm. The comparison results show that the presented analysis method is simple and efficient for engineering system. Finally, the reliability and availability of the protection system architectures based on the two process bus solutions have been compared and some suggestions have been given for the application of process bus.
