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： The invention relates to a method and a system for adjusting the torque of a mass and spinning wheel rotator in a wave power plant. The torque of a rotator rotating around a vertical shaft is compensated partially or completely with a compensating moment which is produced by an electric machine. Acceleration components (ACCx and ACCy) are measured for a given point of the wave power plant's floating body (1) in directions perpendicular to each other. A vector (Vxy) with a magnitude formula (A) and a direction (aAcc) is established for said acceleration components, the direction or angular position (a) of a rotator (2) is monitored and its lag (αLAG) from the acceleration vector's direction (αAcc) is determined. The compensating moment is adjusted as dependent on a compensation factor (B) whose sub-factors are the magnitude of the body's acceleration vector (Vxy) and the sine of the angle of lag (sin αLAG). This is supplemented with a compensation factor based on spinning wheel forces in a manner otherwise similar except that the acceleration must be replaced with a rotation speed (AVx-y) of the body's inclination, which is obtained from an inertial sensor 821). and the mass must be replaced with a gyro force which is dependent on the inertia and rotating speed of a spinning wheel.

摘要： A power generating system includes a wind turbine driven generator, the wind turbine having a wind driven rotor with a plurality of variable pitch angle blades. The blade angle is scheduled during acceleration and deceleration of the wind turbine by open loop controls to minimize stresses, and is scheduled during powered operation by closed loop controls to maintain desired torque or speed. The closed loop controls contain an integrator which produces an integral blade angle control signal. The scheduled blade angle is fed back to the integrators through an integrator tracking network to maintain the integral blade angle control signal at all times within a preselected range relative to the scheduled blade angle.

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.
