A TWACS SYSTEM ALARM FUNCTION FOR DISTRIBUTION AUTOMATION

A new application designated as the ''System Alarm Function'' is made possible by using the ''Unsolicited Inbound'' capability recently deve loped for the Two Way Automatic Communication System (TWACS) System-10 , which is already used by several electric utilities in the USA for d emand 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 collisio ns between multiple alarms and the effects on the ''alarm response tim e'' are discussed in detail. This master-to-master relationship betwee n remote transponders in the distribution network and the central cont rol computer opens the door to multiple functional capabilities in the area of distribution automamation and remote monitoring.
