Abstract :
The Murray Hydroelectric Project, a two-unit, 39 MW total rated capacity, run-of-the-river facility located on the Arkansas River, is described. The emphasis of the paper is on the project´s electrical features. The two generating units are of an open-pit design with horizontal double-regulated turbines. Turbine rated speed in 46 RPM. The generator is rated 22.77 MW at a power factor of 0.9. The rated voltage is 6.9 kV. The author also discusses the plant´s mechanical-hydraulic governor, its electrical system, a 5.7 mile (9.2l-km), 115 kV transmission line, the plant´s black-start capability, its mechanical systems, and the plant, unit, and offsite control systems
