	The Altheim Rankine cycle TURBOGENERATOR 1 MWel Organic Rankine Cycle Power Plant powered by low temperature ...
		The turbogenerator uses the hot geothermal water to pre-heat and vaporise the working fluid in the evaporator.
		The turbogenerator control is implemented by means of a Programmable Logic Controller which handles the digital and the analog signals of the plant: in this way, the presence of an operator is required only to turn on the start key and periodically check the status of the unit.
		The turbogenerator operation is smooth and the personnel requirements are negligible.

	Solar heat pipe feedback turbogenerator - Patent 4122356
		A solar heat pipe turbogenerator according to claim 7 having means on the cooling-heating fluid passage walls for increasing conductivity from the cooling-heating fluid to said walls and for increasing the turbulence of flow of such fluid.
		A solar heat pipe turbogenerator according to claim 10 having associated with it means for removing heated cooling-heating fluid after it has been employed to cool and condense the gas from the vaporizable heat pipe liquid and without using it to heat the liquid in the evaporating section of the heat pipe.
		In that application the employment of a turbogenerator to generate electricity is described, as is the conservation of energy imparted to the cooling fluid employed by condensation of the gas from the vaporizable heat pipe liquid.

	U.S. Patent: 6093975 - Turbogenerator/motor control with synchronous condenser - July 25, 2000
		In order to start the turbogenerator, electric current is supplied to the stator coils of the permanent magnet generator/motor to operate the permanent magnet generator/motor as a motor and thus to accelerate the gas turbine of the turbogenerator.
		Alternately, a turbogenerator control system can utilize a high frequency inverter synchronously connected to the permanent magnet motor/generator of a turbogenerator, a low frequency load inverter, a direct current bus electrically connecting the two (2) inverters, and a central processing unit which controls the frequency and voltage/current of each of the inverters.
		Regardless of the number of turbogenerator sets, shown for purposes of illustration only as three (although it could be even one or a higher number), a single synchronous condenser 260, line commutated inverter 264 and battery 266 connected to the system bus 254 is all that is required.

	Armor-plated auxiliary power
		During turbogenerator start-up, the power-electronics unit (PEU) incorporates an inverter that uses dc power to drive the PM machine (rotor and stator) as a motor, thereby eliminating the need for a separate starter.
		Once the turbogenerator is operating at its design speed (66,000 rpm), the same PM machine acts as a generator supplying power to the vehicle on demand.
		The PEU, which resides in the UAAPU between the vehicle bus and the turbogenerator, is required to drive the PM machine as a motor during start-up and to condition the electrical power out of the PM machine during its generating mode.

	Turbogenerator power control system - US Patent 6495929 (Site not responding. Last check: 2007-10-26)
		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 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.

	esp@cenet description view
		While an individual permanent magnet turbogenerator may only generate 24 to 50 kilowatts, powerplants of up to 500 kilowatts or greater are possible by linking numerous permanent magnet turbogenerator/motors together.
		[0008] In order to start the turbogenerator, the present invention proposes that electric current is supplied to the stator coils of the permanent magnet generator/motor to operate the permanent magnet turbogenerator/motor as a motor and thus to accelerate the gas turbine of the turbogenerator.
		The permanent magnet turbogenerator 10 is commanded to a power set-point with speed varying as a function of the desired output power.

	Turbogenerator power control system - Patent 6325142
		If a turbogenerator with a conventional system for controlling its power generation were utilized to power a pump-jack type oil well, the turbogenerator's power capability would have to be sufficient to supply the well's peak power requirements, that is, about four (4) times the well's average power requirement.
		In other words, the turbogenerator would have to be about four (4) times as large, four (4) times as heavy, and four (4) times as expensive as a turbogenerator that only had to provide the average power required by the oil well rather than the well's peak power requirements.
		This means that the size of the turbogenerator might otherwise have to be increased by a factor of four (4) and the turbogenerator might otherwise experience cyclical variations in operating speed and temperature, suffer excessive centrifugal and thermal stresses, and operate unstably and operate with low efficiency.

		If a turbogenerator rotates in overdrive, the turbine will become damaged very quickly and finally be destroyed unless halted.
		The turbine’s failsafe is assessed according to several criteria, including the level of overdrive protection, the on-line level of vibration measurements and separate vibration measurements and their number, a range of temperature measurements, the structure of the lubrication oil system and check-ups etc.
		Risk level assessments of turbogenerators are time and resource intensive, beginning with co-operation between the customer and inspection and maintenance organisations providing special services.

		There is no mechanical connection between the turbogenerator shaft and the propeller shaft, allowing both to turn at their disparate efficient speeds.

		However, each turbogenerator room contained two turbines, each driving a single generator, versus one turbine driving two generators as in the battleships, and additional SSTGs were fitted.

	Liquid fuel injector system - Patent 6178751
		The turbogenerator 12 generally comprises a permanent magnet generator 20, a power head 21, a combustor 22 and a recuperator (or heat exchanger) 23.
		Ignition of the liquid fuel from the liquid fuel injectors 14 produces heat and the liquid fuel flow is sustained and accelerates the turbogenerator which raises the pressure of the turbogenerator compressor 30.
		As the turbogenerator compressor 30 increases the pressure of the combustion air, the liquid fuel pressure must be correspondingly increased to keep it somewhat higher so that there is a positive flow of liquid fuel to the combustor injectors.
