This paper sstate the characteristics of sand particles in Yanguo- xia reservoir, the special features of the cavitation of turbine blades and the repair of their shape form. It also presents a proposal for bla de shape drawing, and a preliminary discussion about the damage or turbine rotor by sand particles in the silted water stream. The repair of blade form not only restored the output of the turbine units, but also prolonged the duration of maintenance and diminished the amount of welding work.

The adjustable-speed pumped-storage generator-motor is excited by two-order three-phase alternating current. The rotor of generator-motor is cylindrical, and the windings of rotor are fabricated on three-phase distributed windings basis. Thc functions of this generator-motor is identicalwith conventional pumped-storage generator-motor. The variable range of imput power can reach ± 80MW as pumping operation with a definite head, and it can stabilize the frequency of electrical sys-tem. The generator can operate with optimum output speed. The generator can operate with optimum output speed. The range of output variable is wide. The overall efficiency is high with partial load. It can control active power swiftly (about 10ms) even if no apply governor, and have no relation with pump-turbine output. It can improve the stabilization of system, and control over-voltage caused by all troubles. It can operate continually when there are over-voltage, failure of rotation direction chang-ing and system troubles.
