Abstract:
|
The continuous and accurate information of
generator speed in wind energy application is an essential
requirement in order to get the maximum power at given tip
speed ratio, since the maximum power is almost an cubic function
of generator speed. This paper studies a Frequency Locked Loop
(FLL) - based controller for estimating the rotor speed of the
Permanent Magnet Synchronous Generator (PMSG) in a Wind
Energy Conversion Systems (WECS). The proposed system
consist on get the direct sequence component of generator voltage
by means a Dual Second Order Generalized Integrator (DSOGI)
and applying a FLL for estimating the generator frequency and,
hence, its rotor speed. Using a Proportional Resonant (PR)
control, the rotor position is not required and thus a lot of
mathematical operations are avoided. Simulation using
MATLAB/Simulink and PowerSim shows that using a FLL leads
to a simpler and reliable sensorless technique. |
