Abstract

In view of the traditional brake system and method exists the problems of the impact on wind power system is too serious and power generation efficiency is too low, this paper provides a kind of brake system and method that can improve the power generation efficiency and service life of wind power system. Add a current detection circuit in the brake system, current detection circuit is used for detects at least one phase short circuit current value of three-phase armature windings, and pass the current signal to the controller to control use and release of mechanical braking and electromagnetic braking. Analyzes the braking principle of mechanical and electromagnetic brake, and the method of improved braking system, the improved braking system makes the rotate speed of wind turbineÿmanageable, improved the power generation efficiency,stability and service life of the wind power generation system effectively.
