NDLI: Availability analysis of power substation automation architectures with PRP and HSR protocols

Content Provider	IET Digital Library
Author	Rubinstein, Marcelo G. Vinha, Thiago M. da
Abstract	Industrial automation has been widely used in electric power substations. In this context, the IEC 61850 standard provides for the utilisation of redundancy in the data link layer to increase frame reception probability. This study aims to evaluate the availability of two power substation automation architectures based on the IEC 62439-3 standard, which describes two redundancy protocols named parallel redundancy protocol (PRP) and high-availability seamless redundancy (HSR). The authors evaluate both architectures using either PRP or HSR protocol against using no redundancy protocols. The reliability block diagram method has been used, and afterwards, the mean time to failure and availability have been calculated. Results show that the utilisation of redundancy protocols allied to the repair during the mission allows classifying the architectures in the higher availability class according to CEI IEC 870-4.
