Reduction of water hammer in pressure conduits by programmed closing of the turbine gate apparatus

Abstract

1. The implementation of programmed closing for various types of turbine speed governors does not present technical difficulties when using the reliable design of the PCD developed and introduced at the Charvak hydrostation; the PCD can be implemented by the hydrostation personnel from the drawing of Soyuztekhenergo. 2. At various hydrostations the hammer pressure can be reduced by 30–50% of its existing value without an additional increase of speed when dropping the load.
