Abstract
PURPOSE:To improve reliability with a small displacement pump, in an exhaust controller of reversible pump turbines for pumped storage power plants, by such constitution that an abnormally high water level in a drain water pit is detected and an exhaust device is closed at the time of abnormally high water level independently of the controller. CONSTITUTION:When a pump is started, a level of water in a runner chamber 1 is depressed by compressed air from a feed air valve 9, if rotation of a dynamotor, not shown, connected to a main shaft 3 reaches a rated speed, an exhaust command is output to open an exhaust valve 10. Then if priming water pressure in the runner chamber 1 reaches a prescribed value, a pressure relay 16 is operated to close the exhaust valve 10. In this case, if an abnormally high water level of a water drain pit 12 is detected by a water level detector 14A, an electromagnet of the exhaust valve 10 is urged by a circuit, independent of a control circuit of the controller, and the valve is closed. Accordingly, discharge of the drain pit 12 at an abnormally high water level can be prevented to both form a drain pump 15 to small displacement and improve reliability.
