Abstract

Abstract - Tidal power is one of new and renewable energy sources. The seawater is stored inside a tidal embankment built at the mouth of a river or bay, where tides ebb and flow. The water turbine-generators produce power by exploiting the gap in the water level between the water outside and inside the embankment. Tidal power plant is a large plant that is installed on the sea. And then, the facility's operations and a separate control system for monitoring and maintenance is required. However, this plant predictive control of building systems and technologies have been avoided the transfer of technology from advanced global companies. Accordingly, the control system for core technology development and localization is urgently needed. This paper presents modeling and simulation using by PSS/E about generator, governor, exciter, and power system stabilizer for control system in Sihwa tidal power plant to improve the efficiency and develope of core technology. And the dynamic characteristics of governor and exciter were analyzed.Key Words : Control system, Dynamic characteristics, Exciter, Governor, New and renewable energy, Sihwa tidal power plant, Power system stabilizer, PSS/E, Water-turbine generator †교신저자, 종신회원 : 강릉원주대학교 전기공학과 교수․공박E-mail : cwpark1@gwnu.ac.kr*정 회 원 : 강릉원주대학교 전기공학과 석사과정**정 회 원 : 강릉원주대학교 전기공학과 석사과정 접수일자 : 2012년 10월 5일최종완료 : 2012년 11월 12일
