Abstract

This invention discloses a wind-mill generator characterizing that relative displacement occurs between the rotor and the stator by a driver, therefore, the magnetic induction volume between them is changed to alter generation power and control the action moment and generation frequency between them so as to increase the generation efficiency of wind-mill generation especially low rate generation and reduce the cost of constant-frequency control. This invented generator can be designed to two kinds: outer rotor and inner rotor.

Description

technical field [0001] The invention relates to a generator, in particular to a wind power generator. technical background [0002] Since the wind power varies with the cube of the wind speed, the power output of the fan varies widely with the wind speed. This feature of wind energy makes the power generation of wind turbines at cut-in wind speed and cut-out wind speed different by thousands of times, and the frequency changes by nearly a hundred times. [0003] The current wind turbines operate below the designed rated power, and the rated power of the wind generator usually corresponds to the rated wind speed; when the wind speed is higher than the rated wind speed, the control system of the fan changes the state of the wind blades to "overflow" part of the wind energy, making Wind turbines run at rated power to avoid burning out the generators. At this time, the "spillover" wind energy is not utilized. It can be seen that the rated wind speed is designed as the cut-out...
