The two Priority One activities have continued to receive major attention during this reporting period. Application credits for HVDC systems inbedded in ac links are expected to evolve out of a system study wherein dc is introduced into a system where the breakeven criterion is not satisfied. Alternative benefits of the dc link will be quantified in an attempt to develop an expanded economic basis for HVDC systems. Discussions have been initiated with system planners at American Electric Power Service Corporation to see if this type of study could be of benefit to them. Discussions will also be explored with system planners from other utilities. HVDC circuit breaker development is being examined. There is a clearly definable relationship between the exploration acceptance of multiterminal dc systems and the availability of a dc breaker. Further investigation of dc interruption techniques is recommended, together with the establishment of operating criteria and design specifications. Additionally, a definitive system study wherein the operating parameters of the breaker are examined should be undertaken. It is believed that the key relationship exists between breaker speed of operation, control coordination among terminals, and ac system stability.
