The ring bus configuration, a topology commonly used at transmission voltage levels, can provide significant enhancements in system reliability and improvements in operating procedures, while remaining an economical and cost-effective design. This paper analyzes the enhancements in reliability and improvements in operating procedures afforded by incorporating the ring bus topology at the transmission level, and then explores further enhancements in reliability and operation by implementing the ring bus configuration on the distribution system.
