Independent Load Sharing of UPS systems connected in Parallel
병렬운전 UPS 시스템의 독립 부하 분담 특성
Abstract
This paper describes characteristics of independent load sharing of parallel UPS systems and proposes a method of control which does not require control interconnections at each UPS system and compensates for line impedance. Simulation results of a two-module UPS system with different power latins and line impedance have demonstrated the feasibility of the proposed control scheme in load sharing.
