Abstract

A voltage sag is a short-duration reduction in rms voltage, and utilities have been faced with rising numbers of complaints about the quality of power due to voltage sags. In this paper, vulnerable areas of voltage sag are determined using representative loads at the buses. The CBEMA curves of the representative loads are used to determine whether the bus is vulnerable or not. Also, the ares are displayed with geographical information in order to help operators understand the situation going on easily. The proposed simulator is applied to Jeju power system to show its capabilities.
