VARIABLE PERFORMANCE ELECTRIC GENERATOR

摘要

Disclosed is a variable performance large electric generator, comprising, a rotor arranged along a centerline of the generator; a core arranged coaxially and surrounding the rotor; a plurality of stator windings arranged within the core; a stator frame arranged to fixedly support the core and rotationally support the rotor; a gas cooling system that circulates a cooling gas within the generator; a liquid cooling system that circulates a cooling liquid to cool the stator windings wherein the cooling ability of the liquid cooling system is a function of a required generator parameter; a pressurizing system that operatively pressurizes the cooling gas to a maximum pressure of two (2) bar relative to atmospheric pressure, wherein the pressurizing system continuously determines the cooling gas pressure based upon a required generator parameter; and a control system that controls the cooling ability of the liquid cooling system in conjunction with the cooling gas pressure.
