ABSTRACT:
A system for providing seal oils to a gland seal that surrounds the shaft of a generator with the temperature differences between the oils minimized. The temperature of one of the seal oils is utilized as a reference for controlling the oil temperature of the other seal oil. In particular, the temperature of the air-side seal oil is determined and utilized as a reference. The temperature of the hydrogen-side seal oil is determined, and a differentiator produces a signal based upon the difference between the air-side and hydrogen-side seal oils to control either the water flow rate to the hydrogen-side cooler, or to control mixing of cooled and uncooled oil in the hydrogen-side of the system. The system advantageously prevents thermal differential expansion from occurring in the generator shaft, and allows for the elimination of a controlled cooler in the air-side oil system. Further, the air-side oil can be suplied from the main lube oil system.
