A Direct Power Controller for Doubly-Fed Induction Generator

Abstract

This paper proposes a direct power control scheme

for doubly-fed induction generator for variable speed wind power

generation. Using a stator flux decoupling and deadbeat control loops

the algorithm calculates the rotor voltage vector to be supplied to the

rotor in order to eliminate the active and reactive power errors that

can achieve high accuracy and fast dynamic power response based

on the estimated stator flux, the active and reactive power and their

errors. Simulations results are carried out for validation of the digital

controller operation.
