Abstract

PURPOSE: To obtain an optimum increased of the oil temperature even at the time of quick starting, by heating the oil at the time of starting a rotary electric machine by an electric heater arranged in an oil container and setting the outlet temperature of an oil cooler to a reasonable level according to the number of revolution of the rotary electric machine.
CONSTITUTION: An electric heater 12 and a thermal switch 13 are arranged in an oil container 11 to raise the oil temperature quickly at the time of starting, and the oil is heated before starting until or a little after the rated number of revolution is almost obtained. The oil being supplied by an oil pump 14 of the oil container 11 is thermally adjusted by a temperature regulator valve 4 until its temperature is set to the level determined by an oil cooler 2, and the oil is fed to a rotary electric machine 15. Then, exhausted oil 16 is returned to the oil container 11. After a turbine leaves its preparatory driving stage the quantity of cooling water is decreased by raising the set point of the outlet temperature of the oil cooler 2, and the control is thus effected to obtain the best oil temperature for an increasing number of revolution.
