Method of operating a fluid-cooled hydropower generator

Patent ·
OSTI ID:7295475
A method of operating a fluid-cooled hydropower generator of a hydroelectric facility such as a pump storage plant is described: The generator of the plant being alternately in the active and shutdown condition as required and being equipped with a circulation system for conducting fluid coolant for cooling the generator, the circulation system including control means for controlling system leaks and the conductivity of the fluid coolant; a heat exchanger connected into the circulation system for cooling the fluid coolant, the heat exchanger, in turn, having its own circulation system for fluid cooling the same; and, a pump for pumping the fluid coolant of the circulation system through the heat exchanger and the circulation system. The method is comprised of maintaining the operation of the pump and the control means when the hydropower generator is in the shut-down condition to pump the fluid coolant through the circulation system and the heat exchanger; and, interrupting the circulation system for fluid cooling the heat exchanger when the hydropower generator is in the shut-down condition.
