Abstract

The invention is suitable for the field of million kilowatt level pressurized water reactor nuclear power station control, and provides a method and a system for monitoring heat condition of a generator stator winding of a nuclear power station. The method comprises: acquiring outlet water temperature information of each stator bar included in the generator stator winding; generating a radar map used to show the outlet water temperature information of the stator bars according to the acquired outlet water temperature information of the stator bars; and showing the radar map which is used to show the outlet water temperature information of the stator bars. Through generating the radar map used to show the outlet water temperature information of the stator bars according to the acquired outlet water temperature information of the stator bars, operating personnel of the nuclear power station can rapidly and accurately know about the heat condition of the generator stator winding according to the outlet water temperature information of each stator bar shown in the radar map, and rapidly and accurately detects heat faults of the generator stator winding, thereby ensuring safe operation of electric generators used in the nuclear power station.

Description

technical field [0001] The invention relates to the control field of a million-kilowatt pressurized water reactor nuclear power plant, in particular to a method and system for monitoring the thermal state of a stator winding of a nuclear power plant generator. Background technique [0002] The generator is a key equipment in the million-kilowatt pressurized water reactor nuclear power plant, and the thermal failure of the stator winding of the generator is one of the frequent faults of the generator cooled by water and hydrogen. Generator stator windings generally contain several stator bars, and the outlet water temperature of stator bars is a key parameter for judging the thermal fault of generator stator windings. Therefore, in order to meet the extremely high safety requirements of nuclear power plants, it is necessary to The water outlet temperature of each included stator bar is monitored to judge whether a thermal fault occurs in the stator winding of the generator ac...
