摘要： A method of operating a combined-cycle gas and steam turbine power generating system on a single shaft (16) uses as a feedback to the speed control or governor a signal (22) representing the total power output of the generator less the total output of the steam turbine (12), which is then correlated with the error signal beetween the actual and reference speeds to alter the fuel flow to the gas turbine. By compensating the measured generator output by subtracting a value (24) representative of the steam turbine output so that the compensated signal (26) represents the contribution of only the gas turbine (10) to the generator output, a constant settable droop speed control system may be used in a single-shaft combined-cycle steam turbine and the gas turbine system to compensate for variable heating fuel value and/or changing combustion efficiency in dry low NOx combustion systems.

摘要： The expected visual detractions posed to the environment by a wind power station play an increasingly important role in the approval and acceptance when planning and erecting wind power stations. When, for example, a wind power station is placed in the vicinity of a residential building, it is possible, at unfavorable positions of the sun, that the wind power station, i.e. the rotor thereof, is located between the sun and the residential building. When the sunshine is not obscured by clouds, the rotating rotor constantly casts a (heavy) shadow onto the property. The shadow cast by the wind power station onto the adjacent property is often perceived by the residents as being very disturbing. Even when the wind power station satisfies the legal requirements concerning approval, it is, however, not always guaranteed that the unwanted cast shadow is prevented. The aim of the invention is to create a wind power station by means of which the control of shadows cast thereby is improved. This is achieved by a method for operating a wind power station during which a first intensity of light is detected in an area of direct incident light radiation, and a second intensity of light in a shaded area is detected. The wind power station is then switched off when the difference between the first intensity of light and the second intensity of light is greater than a preset value.

摘要： When planning and setting up wind power installations, the visual detractions to be expected on the part of the wind power installation on the environment play an increasingly important part in approval and acceptance. The shadow casting caused by the wind power installation on the adjoining properties is often perceived by the residents as being very troublesome.A wind power installation is provided by means of which shadow casting regulation is improved. That is achieved by a method of operating a wind power installation wherein a first light intensity is detected in a region of direct light irradiation and a second light intensity is detected in a shadowed region, and wherein the wind power installation is shut down if the difference between the first light intensity and the second light intensity is greater than a predetermined value.

摘要： A controlled direct drive engine efficiency uses positive-displacement power produced from a thermal energy source (or sources), which may include combustion energy. Engine power production is from a plurality of cylinders appropriately controlled by a hydraulic drive unit to add to or subtract from such power output to adjust cyclic variations, thus producing a desired velocity profile for a piston (or other mover) in a fluid-displacement cylinder that is being used to effect pumping (or compressing) of liquids, gases, or vapors. The overall system is particularly suited to use a Modified Brayton thermodynamic cycle where the power output is delivered through a common rod to a positive displacement fluid pumping or compressing device. Interconnected with that common rod is a double-acting hydraulic cylinder which is operated in conjunction with a rotary, variable volume hydraulic motor/pump to effect the desired adjustment. By using a plurality of power outputs from such a Modified Brayton cycle (or other cycle), which outputs are phased to operate complementary to one another, power is transferred between individual power outputs to efficiently and smoothly operate a plurality of fluid-displacement devices.

摘要： The shaft of a wind turbine is connected to the rotor of a three-phase AC generator. The rotor windings, in turn, are connected to the rotor windings of a DC-energized, AC exciter via a differential frequency-converter. A frequency-detector, which monitors the output of the AC generator, is connected to the input of the frequency-converter to maintain the output of the generator at 60 Hz. A "real" power sensing circuit, connected to the output of the generator, develops a control signal which, when subtracted from a second control signal generated by a power management control circuit, maintains the power output of the generator at the maximum possible level for each particular power output from the wind turbine which drives the generator.

摘要： A control system for adjusting the pitch of variable-pitch angle blades in a wind turbine for generating electric power maintains the control signal for the variable-pitch angle blades above a minimum level representing the minimum desired angle of the variable-pitch blades. The control system includes a subtractor for generating a difference signal; a device for generating from the difference signal a first blade control signal greater than a minimum level, from a device for generating a second blade control signal greater than a minimum level, from first blade control signal and the difference signal; a device for generating a third blade control signal for adjusting the pitch of variable-pitch angle blades, from second blade control signal and power rate signal. All devices include limiters which limit their respective output signals to a minimum level representing a preset minimum blade angle.
