能とする発電機冷却ガス制御装置。[Claims for Utility Model Registration] A generator that uses hydrogen gas as a cooling medium, a load detection device that detects the operating load of the generator, and a hydrogen gas pressure detector that detects the pressure of hydrogen gas as a cooling medium inside the generator. In a system that has a hydrogen gas supply device that supplies hydrogen gas as a cooling medium into the generator and a hydrogen gas release device that releases the gas inside the generator to the outside of the generator, the load detection device detects a gas pressure calculation circuit that calculates a minimum allowable gas pressure inside the generator according to the operating load of the generator;
It has a comparator that compares the generator internal gas pressure detected by the hydrogen gas pressure detection device and the minimum allowable value calculated by the gas pressure calculation circuit, and the generator internal gas pressure is higher than the minimum allowable value. In case,
Activating the hydrogen gas release device to reduce the gas pressure inside the generator, and when the gas pressure inside the generator is lower than a minimum allowable value, activating the hydrogen gas supply device to increase the gas pressure inside the generator. This is a generator cooling gas control device that enables optimal operation of the generator's internal gas pressure.
