说明: The generating systems use Doubly-Fed Induction Generators (DFIGs) to achieve high
conversion efficiency and to reduce the installation cost. This paper presents a modeling and Maximum
Power Point Tracking (MPPT) control method of DFIG-based variable-speed wind energy conversion
system. The generator considered is a wound rotor induction machine whose stator is connected directly
to the grid and the rotor is fed through back-to-back Pulse-Width Modulation (PWM) converters. Stator
flux-oriented vector control is applied to control the active and reactive current loops independently. The
MPPT control method in a Wind Energy Conversion System (WECS) is proposed. The proposed control
solution aims at driving the position of the operating point near to optimality. This is a very important
aspect to maintain DFIGs efficiently in a variable wind speed. The wind generator is modeled in RSCAD
program which is interfaced with the Real Time Digital Simulator (RTDS).
