Water temperature monitoring method and blockage handling method for generator stator of 1000 megawatt nuclear power plant

Abstract

The invention discloses a water temperature monitoring method and a blockage handling method for a generator stator of a 1000 megawatt nuclear power plant. The water temperature monitoring method for the generator stator of the 1000 megawatt nuclear power plant comprises the following steps of: determining the outlet water temperature of the stator under different working conditions, converting the determined outlet water temperature of the stator under different working conditions into the outlet water temperature of the stator under a benchmark working condition to obtain converted outlet water temperature, judging whether the outlet water temperature of the stator is abnormal or not according to the converted outlet water temperature, adjusting the outlet water temperature of the stator according to judgment results and handling the blockage of the stator. By monitoring the water temperature of the stator during the operation of the generator of the 1000 megawatt nuclear power plant, the abnormalities of the water temperature of the stator can be found in time, the parameters such as hydrogen pressure, bypass purification flow and the like of the generator can be effectively adjusted or the blockage of the generator stator can be handled, the generating efficiency of the generator can be ensured and the problems of too high generator temperature, forced shutdown or stator winding burnout can be avoided.

Description

technical field [0001] The invention relates to the key technology of a generator of a million-kilowatt nuclear power plant, and more specifically, the invention relates to a water temperature monitoring method and a blockage treatment method for a stator of a million-kilowatt nuclear power plant generator. Background technique [0002] The water-cooled turbogenerator (hereinafter referred to as the generator) used in the mega-kilowatt nuclear power plant is a kind of giant turbogenerator. In the generator mentioned above, both the stator winding and the rotor winding of the generator adopt hollow copper wires (called stator) and pass water to cool the generator. Because of the high specific heat of water, heat can be taken away directly during the flow process, which is beneficial to the heat dissipation of the generators of mega-kilowatt nuclear power plants during operation, so it can significantly improve the efficiency of generators, especially the generators of mega-ki...
