| Abstract |
As a brake system for small wind turbine,
mechanical brake and electric brake by the short circuit of
3-phase permanent magnet generator are used. However, an
electric braking method may damage the rotor and/or
blades by rapid stop of the generator revolution. Moreover,
generator winding may also be damaged by large shortcircuit
current. In this paper, the electric braking method
using NTC thermistors (negative temperature coefficient
resistors) is proposed as a braking system for a cheaper and
safe micro wind turbine. |
