Abstract:

The operation condition of 700MW hydrogenerators of Three Gorges Project is the most difficult among the same kinds of units, which brings great challenge to its stable operation. Aiming at the design of the units, we had carried out a series of systematic researches, including relative parameters to the safe and stable operation, optimal match of performance parameters, stable operation measures as well as application of new technologies. The research results had been applied in the design, manufacture of unit and operation of plant, and a series of problems of giant hydrogenerator had been solved such as excessive hydraulic pulsation at high load area, safe and stable operation under large fluctuation of water head.

Key words: cooling technology of hydrogenerator, safe and stable operation, hydrogenerator units, Three Gorges Project
