Distributed Control Applications for Utility Hydroelectric Plantsby Dale E. Kramer, Power Engineers Inc, United States,
Scott R. Hamilton, Power Engineers Inc, United States,
Abstract: In 1984, Washington Water Power began a program to improve monitoring and control systems for hydroelectric plants. The control systems being improved with distributed control equipment are: voltage regulators; turbine governors; spillgate drives and forebay level control; efficiency optimization; thrust bearing monitoring; remote control and plant monitoring. Each control system was redesigned from sensors through actuators to ensure minimum operating, maintenance and capital expenses while maximizing operational flexibility.
