Transcripción del abstract original del autor: We have developed a reliable countermeasure for commercial power failure, named "Gas Engine Gene-Live" without considerable increase in cost. This system can carry out continuous operation of the important loads with a gas engine generator without any power cut when commercial power failure occurs. It can detect commercial power failures within 7.5 milliseconds, opens the certain circuit breaker before cogeneration systems bear all the loads of premises, and enables the generator to continue to supply to important loads that was selected beforehand. Furthermore, it automatically re-connects the generator to the grid when the commercial power recovers. In this paper, we'll show the summary of the results of over four hundred comparison experiments between this system and other conventional systems. We used actual gas engine generator for this experimental proof. The results certified many advantages of Gas Engine Gene-Live.
