Abstract: A system for determining wind turbine tower base torque loads including a controller configured to determine a torque load of a base of a tower of a wind turbine according to a computation of an effective height of the wind turbine multiplied by a wind force upon a rotor of the wind turbine, and generate a control signal representing the torque load. A method for determining wind turbine tower base torque loads including determining a torque load of a base of a tower of a wind turbine according to the foregoing computation, and generating a control signal representing the torque load.

Abstract: A system includes sensors configured to measure parameters related to a vessel including liquid level, gas flow rate, pressure in the vessel, temperature of the vessel, and feed-liquid flow rate. A signal processing unit receives sensor output signals and generates a first filtered output signal representative of liquid level, a second filtered output signal representative of gas flow rate, a third filtered output signal representative of feed-liquid flow rate, a fourth filtered output signal representative of vessel pressure, and a fifth filtered output signal representative of vessel temperature. A flow demand control unit receives the first filtered output signal and generates an output signal representative of feed-liquid flow demand. A shaping unit receives the second, fourth, and fifth filtered output signal and generates an output signal representative of shaped gas flow rate as a function of pressure, temperature, or combination thereof in the vessel.
