Abstract:

Based on the turbine model test, the starting-up strategies for generator-units under different water heads of the right bank power plant of Three Gorges Project are discussed according to the actual incoming flow of Yangtze River, and different dispatching schemes and overhaul strategies are compared and analyzed. The optimum starting-up water head for the different types of units of the right plant are figured out. The results show: under different water heads, power plants with units of different hydraulic performance should adopt specific starting-up order and dispatching schemes, which will generate more economic benefits without increasing the investment. The research can provide new ideas of increasing power output for power plants with types of units. 

Key words: power output, power plants with units of different hydraulic performance, starting-up strategies, model test, water consumption rate, power plant on the right bank of TGP
