Development of an Under-Voltage Relay Algorithm Module for a Network Based Protective Relay Simulator

네트워크 기반 보호계전기 시뮬레이터용 저전압 계전 알고리즘 모듈 구현

This paper proposed an under-voltage relay algorithm module for a network based protective relay simulator. The simulation system is based on the client-server paradigm. The relaying simulator which consists of server-side relay models and user interface provides network-based simulation environment for a variety of protective relaying algorithms. The performance of the relay algorithm was verified by comparing the results of under-voltage relay algorithm in the simulator with the results of the C language implementation.
