A TWACS system alarm function for distribution automation

摘要

A new application designated as the "System Alarm Function" is made possible by using the "Unsolicited Inbound" capability recently developed for the Two Way Automatic Communication System (TWACS) System-10, which is already used by several electric utilities in the USA for demand side management, remote metering and distribution automation is reviewed here. The "Unsolicited Inbound" algorithm development, the operational issues that are pertinent to the understanding of collisions between multiple alarms and the effects on the "alarm response time" are discussed in detail. This master-to-master relationship between remote transponders in the distribution network and the central control computer opens the door to multiple functional capabilities in the area of distribution automation and remote monitoring.
