Control and Protection Design of the Revelstoke Hydroelectric Project

The Revelstoke hydroelectric project on the B.C. Hydro system is a six unit 2910 MV*A remotely controlled powerplant utilizing 500 kV and 230 kV compressed gas insulated switchgear and fiber-optic data acquisition and control techniques. The initial four generating units were placed in service during 1984. The paper describes the basic design of the control and protection aspects of the project with emphasis on approaches taken to provide a high level of operating performance and reliability. Testing techniques and early operating experience are also reported.
