차세대 파워스테이션의 UPS 동작 검출 알고리즘

In this paper, a fault detection algorithm for an UPS operation of power station is proposed. By adapting the algorithm, a grid-connected power station performs a UPS operation when faults such as sag, swell are occurred. Through a computer simulation, grid faults are simulated and the proposed fault detection algorithm using d, q axis observation method is verified.
