摘要： A power control system for a turbogenerator which provides electrical power to one or more pump-jack oil wells. When the induction motor of a pump-jack oil well is powered by three-phase utility power, the speed of the pump-jack shaft varies only slightly over the pumping cycle but the utility power requirements can vary by four times the average pumping power. This power variation makes it impractical to power a pump-jack oil well with a stand-alone turbogenerator controlled by a conventional power control system. This power control system comprises a turbogenerator inverter, a load inverter, and a central processing unit which controls the frequency and voltage/current of each inverter. Throughout the oil well's pumping cycle, the central processing unit increases or decreases the frequency of the load inverter in order to axially accelerate and decelerate the masses of the down hole steel pump rods and oil, and to rotationally accelerate and decelerate the masses of the motor rotors and counter balance weights. This allows kinetic energy to be alternately stored in and extracted from the moving masses of the oil well and allows the oil pumping power to be precisely controlled throughout the pumping cycle, resulting in a constant turbogenerator power requirement.

摘要： A system and method of safely discharging hydraulic fluid from a compressed gas cylinder, comprises filling first and second compressed gas cylinders with compressed gas. A compressed gas dispensing system has a pump that pumps hydraulic oil into the compressed gas cylinders to maintain a desired pressure while gas is dispensed. Gas is dispensed from the first cylinder while hydraulic fluid is pumped into the cylinder to maintain the desired pressure. Once the first cylinder is depleted, the hydraulic oil is discharged from the first cylinder. The process is repeated for the second cylinder. However, the hydraulic oil must be discharged from the second cylinder before the substantial depletion of the gas. To safely discharge the hydraulic oil, compressed gas from the second cylinder is distributed into the first cylinder. Once the second cylinder has reached a safe discharge pressure or volume, the hydraulic fluid is discharged.

摘要： A temperature compensated control system (100) for a hydraulically controlled clutch (18) for controlling a source of rotary power to a load (101) for accelerating the load from a first velocity to a second velocity within a time interval measured from a beginning of the acceleration and ending between first and second times measured from the beginning of the acceleration with the load being variable during the acceleration of the load from the first velocity to the second velocity is disclosed. Gain compensation is provided as a function of temperature of hydraulic fluid within a servo system (110) controlling the clutch. Furthermore, a controller (39) controls the opening of a valve (35) as a function of the sensed temperature during initiation of starting to cause the flow of lubricating fluid into the gearbox to be delayed during the initiation of starting when a sensed temperature is below a set temperature to minimize viscous drag and to cause lubricating fluid to flow immediately into the gearbox when the sensed temperature is above the set temperature.

摘要： A liquid fuel pressurization and control system is disclosed which utilizes either a helical flow pump, or a helical flow pump followed by a gear pump, to pressurize liquid fuel to precisely the pressure level required by a turbogenerator's combustor injectors. This eliminates the need to overpressurize the fuel then regulate the fuel pressure down using a flow control valve or a pressure control valve. The shaft torque and shaft speed of the pump are controlled by the turbogenerator's power controller so as to assure that the turbogenerator's speed is precisely controlled (e.g. within ten (10) rpm out of one hundred thousand (100,000) rpm), and that its turbine exhaust temperature is precisely controlled (e.g. within two (2) degrees Fahrenheit out of twelve hundred (1200) degrees Fahrenheit) over the full range of turbogenerator electrical output power. The system also provides cool, high pressure air to assist atomization of the liquid fuel in the injectors utilizing a variable speed helical flow compressor. The system also adjusts the relative fuel flow through the multiple fuel injectors to aid flame stability at low turbogenerator speeds and low output power levels.
