| titleOfInvention | The maximum torque available field weakening control method of permanent magnetism direct drive wind group of motors |
| abstract | The present invention relates to wind power generation field, will be specifically a kind of maximum torque available field weakening control method for permanent magnetism direct drive wind group of motors, it is characterized in that: the maximal wind-energy Tracking curve that obtains permanent magnetism direct drive wind group of motors: , at given rotating speed Under, with straight, quadrature axis electric current For optimized variable, off-line solves constrained optimization problem, remembers that the optimized variable solution of this optimization problem is , obtain the weak magnetic given value of current of maximum torque available field weakening control method ; With suitable step-length Change rotor speed Even, ; By obtain a series of ( ， ) point is linked to be curve, thereby the weak magnetoelectricity obtaining under every speed flows given curve . According to wind-powered electricity generation unit, control has the particularity of himself, and the overall control strategy of unit makes the torque instruction of magneto alternator and current rotating speed present relation one to one. This is just for the weak magnetic controller design of simplifying wind-powered electricity generation unit provides possibility. |
