摘要： A multi-mode electronic wind turbine control system establishes a reference blade angle for a two-bladed, horizontal axis, variable pitch wind turbine rotor, the blade angle being regulated by a hydraulic pitch change mechanism. The rotor, via appropriate shafts and a gearbox, is coupled to a synchronous generator to produce electrical energy which is fed to a power utility grid. The control system provides closed loop pitch control for rotor acceleration rate during start-up, for rotor deceleration rate during shutdown, for speed control when the synchronous generator is off-line, and for power control when the synchronous generator is on-line. A single control integrator is used for all closed loop operating modes, with a rate limiter circuit in front of the control integrator to prevent integrator overtravel. The integrator has maximum and minimum blade angle stops, the minimum stop being variable as a function of rotor speed and wind speed. When on-line, power control is provided by a unique shaft torque control using proportional plus integral plus derivative controls in combination.

摘要： Wind energy is used to drive a wind turbine, which is in turn connected to an electrical generator to produce electrical power. The pitch angle of the wind turbine blades is controlled in a closed loop manner to maintain either a constant generator speed for isolated power generating stations or when the generator is synchronized to the load, or constant generator output power or shaft torque when the generator is connected to an electrical grid. Open loop acceleration and deceleration schedules are provided to minimize blade stress and shaft torque variations during start up and shutdown transients, limiting blade angle excursions as a function of wind velocity and speed. The schedules may be implemented either electronically or by a suitably programmed digital computer. The gains in the speed, torque and power loop controls are scheduled as a function of average wind velocity to optimize stability and response. An anticipatory blade angle schedule responsive to instantaneous wind velocity is added to the desired blade angle reference from the closed loop controls to minimize transient excursions in output power or generator speed resulting from wind gusts.

摘要： A variable speed wind turbine includes a frequency converter which converts variable frequency AC from a turbine driven AC generator to fixed frequency AC for delivery to a power grid. The frequency converter is typically an electronic cycloconverter or rectifier-inverter and is also used to control the power flow from the AC generator to the grid which thereby controls the air gap torque between the generator stator and rotor. The turbine speed is maneuvered to increase efficiency by precisely controlling the air gap torque according to a schedule defining sensed generator speed versus sensed generated power.

摘要： A gas turbine engine bleed air system in which air flow from a high pressure and a low pressure compressor stage of a gas turbine engine are mixed together by controlling the pressure at the outlet of a proportional valve. The pressure is controlled by modulating the flow area of the proportional valve through which the high pressure air flows in order to achieve a scheduled pressure value. The scheduled pressure value is determined as a function of a temperature error at a location downstream of the proportional valve in the bleed air system.

摘要： An automatic control system includes a multiplier for multiplying the error signal fed to an integrator in accordance with the state of the integrator. The multiplier multiplies the error signal by a unity gain factor over the normal range of integral control; whereas, the multiplier multiplies the error signal by a factor greater than one, typically ten, when the integrator output is saturated at either the minimum or maximum values. The high multiplication value of the error signal ensures a sufficiently quick recovery from an integrator saturation condition.

摘要： A variable speed wind turbine is controlled in a way which avoids the turbine lingering at a critical speed which would otherwise tend to cause excessive vibration. The disclosed method and apparatus increases speed at a selected rate with respect to generator output power except in the vicinity of the critical speed. The selected rate is changed in the vicinity of the critical speed to a different rate which is selected slower in the selected embodiment, to avoid commanding the critical speed. After the output power increases or decreases beyond the critical point, a deliberate discontinuity in the speed command signal is induced. A rapid speed change through the critical speed is accompanied by a corresponding power output change. If the speed is increasing at a selected slower rate below the critical speed, and the speed command signal is stepped to a higher level just before reaching the critical speed, the speed will rapidly increase and quickly pass through the critical speed while the power output decreases. Similarly, if the speed is decreasing at a selected slower rate above the critical speed, and the speed command signal is stepped to a lower level just before reaching the critical speed, the speed will rapidly decrease and quickly pass through the critical speed while the power output increases.
摘要翻译：控制变速风力涡轮机的方式是避免涡轮在临时速度下滞留，否则这样会导致过度振动。所公开的方法和设备除了在临界速度附近之外以相对于发电机输出功率选择的速率增加速度。在所选择的实施例中，所选择的速率在临界速度附近改变为选择较慢的速率，以避免命令临界速度。在输出功率增加或减小超过临界点之后，引起速度指令信号中故意的不连续性。通过临界速度的快速变化伴随着相应的功率输出变化。如果速度以低于临界速度的选定的较慢速度增加，并且速度指令信号在达到临界转速之前阶跃到更高的水平，则速度将快速增加并快速通过临界转速，同时功率输出减小。类似地，如果速度以高于临界速度的选择的较慢速度减速，并且速度指令信号在达到临界速度之前被阶梯化到较低水平，则速度将快速降低并且快速地通过临界速度，而功率输出增加。
