Temperature adjusting system for generator stator cooling water during deep peak regulation period of high-capacity unit

The utility model belongs to the technical field of generator stator cooling water, and discloses a temperature adjusting system for generator stator cooling water during deep peak regulation of a high-capacity unit. A bypass loop pipeline is arranged on a cooling water return pipeline on two sides of a main control electromagnetic valve, a bypass control electromagnetic valve with the drift diameter smaller than that of the main control electromagnetic valve is arranged on the bypass loop pipeline, and a digital thermometer is arranged on a cooling water supply pipeline. The digital thermometer uploads the water inlet temperature of cooling water to a DCS (Distributed Control System) on site to obtain a difference between the water inlet temperature and the hydrogen temperature at the inlet of the generator, and controls the bypass control electromagnetic valve and the main control electromagnetic valve to be opened or closed according to the temperature difference value so as to adjust the flow change of th
