Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] In the embodiment of the present invention, the operating parameters of each stator bar included in the generator stator winding under various operating conditions of the generator are collected, and the collected stator wires included in the generator stator winding under various operating conditions of the generator are collected. The operating parameters of the bars map the outlet water temperature of each stator bar included in the generator stator winding to the outlet water temperature under the generator reference operating condition, thereby eliminating the influence of the generator ...

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 temperature of generator stator windings of a nuclear power station. The method comprises: acquiring operation parameters of the stator bars in a present operation condition of a generator; and mapping outlet water temperature of the stator bars in the present operation condition of the generator to outlet water temperature of the stator bars in a reference operation condition of the generator, and obtaining outlet water temperature mapping values of the stator bars in the present operation condition of the generator. The method eliminates influence of the generator operation condition on the outlet water temperature of the stator bars, so monitored temperature of each stator bar reflects practical temperature state of each stator bar in a more real and accurate manner, and heat faults of the generator stator winding can be monitored accurately in time.

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 temperature monitoring method and system for a stator winding of a generator of a nuclear power plant. Background technique [0002] The generator is a key equipment in a million-kilowatt pressurized water reactor nuclear power plant, and the generator stator winding is the core component of the generator, and the generator stator winding generally includes multiple stator bars. The main problem of generator stator winding is temperature problem. Especially in the field of nuclear power control, because nuclear power plants have extremely high safety requirements, in order to meet the high safety requirements of nuclear power plants, it is necessary to monitor the temperature of the stator windings of generators used in nuclear power plants. [0003] However, the temperature of the stator windings of generators used in nuc...
