Summary on the start-up debugging and trial operation of the first generating units of Three Gorges Hydropower Plant

The Francis turbine for the Three Gorges Hydropower Plant with unit capacity of 700 MW is the largest in the world. In order to check up the design performance, manufacturing and installation quality of the equipment, this paper summarizes the work of the start-up debugging and trial operation of the first generating units of Three Gorges Hydropower Plant. Thus the faults and mistakes could be found out in time in order to make its production operation and power transmission more stable and safe. The main devices of GIS and 2F, 5F have joined in the debugging. According to the requirements of power system, several tests on the generating units and the devices for power transmission that has been just put into production have been taken. In a word, the test results is good and shows that the generating units can be put into business operation.
