METHOD AND SYSTEM FOR ADJUSTING THE TORQUE OF A MASS AND SPINNING WHEEL ROTATOR IN A WAVE POWER PLANT

NºPublicación: EP3243001A1 15/11/2017

Solicitante:
WELLO OY [FI]

Resumen de: WO2016110610A1

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 ( ACC x and ACC y) 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 (α LAG) 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 α LAG). 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.
