1. A turbine generator including a pressure regulation circuit comprising:
the turbine generator comprising a generator frame defining an internal chamber of the turbine generator and housing a portion of a turbine rotor; a controller that determines a pressure within the generator frame; the pressure regulation circuit including a main circuit comprising:
pressure regulator structure that receives fluid, regulates the pressure of the fluid to a predetermined output pressure, and outputs the fluid at said predetermined output pressure, said predetermined output pressure being greater than a desired operating pressure of said generator frame and being less than a predetermined upper alarm pressure; anda primary valve downstream from said pressure regulator structure that is selectively opened and closed by said controller based on the pressure within said generator frame determined by said controller, wherein said controller:
if said primary valve is closed, opens said primary valve to allow said pressurized fluid outputted from said pressure regulator structure to flow into said generator frame upon the pressure within the generator frame being at or below a predetermined lower limit, said predetermined lower limit being no greater than the desired operating pressure of the generator; andif said primary valve is open, closes said primary valve to prevent said pressurized fluid outputted from said pressure regulator structure from flowing into said generator frame upon the pressure within said generator frame being at or above a predetermined upper limit, said predetermined upper limit being no greater than said predetermined output pressure and being greater than said predetermined lower limit. |
