시뮬레이터 감시를 위한 DAS 시스템의 구축

The Construction of DAS System for Supervising of Power System Simulator

This paper presents the construction of Digital DAS system for supervising of power system simulator (KERISIM) which is developed in KERI. This system is composed of input transducer, input conditioner and digital supervisor. In order to watch P,Q,V,I, Power Factor and RMS in KERISIM successively, Digital arithmetic algorithm is accomplished to calculate Real/Reactive power from voltage/current data which is transferred by secondary part of CT/PT in simulator.
