DFIG-based Wind Power Conversion System

By Akshay Kumar

Master's Thesis from the yr 2014 within the topic Engineering - energy Engineering, grade: 7.8, Ajay Kumar Garg Engineering collage, direction: M.Tech, language: English, summary: Wind iteration has develop into crucial exchange strength resource and has skilled elevated growth in India prior to now decade. whereas it has nice power in its place to much less environmentally pleasant strength assets, there are numerous technical demanding situations that reason wind to be thought of negatively by way of many utilities. Wind strength conversion platforms be afflicted by the truth that their actual strength new release is heavily depending on the neighborhood environmental conditions.

The Doubly Fed Induction Generator (DFIG) dependent wind turbine with variable-speed variable-pitch keep an eye on scheme is the most well-liked wind energy generator within the wind strength undefined. This laptop may be operated both in grid attached or standalone mode.

during this thesis, a close electromechanical version of a DFIG-based wind turbine attached to strength grid in addition to individually operated wind turbine process with diverse sub-systems is built within the MATLAB/SIMULINK atmosphere and its identical generator and turbine regulate constitution is discovered. during this regard following configurations were considered:
•DFIG with Battery garage sub-system
•DFIG with Buck-Boost converter
•DFIG with transformer
•DFIG with 3-winding transformer
Addition of battery garage and buck-boost converter sub-systems into the process allows not just dispatching of generator energy but additionally decreases the range of their reactive energy specifications. the complete keep an eye on over either energetic and reactive energy is feasible by way of transformer among DFIG and rotor facet converter.
The regular kingdom habit of the final wind turbine process is gifted and the regular nation reactive energy skill of the DFIG is analyzed. it's been proven that significant a part of the reactive strength can be provided from rotor part converter to lessen the general ranking of the generator.
The DFIG with above pointed out sub-systems is hooked up to grid. the complete harmonic distortion research and potency are conducted. it truly is came upon that DFIG with transformer in among desktop and rotor facet converter has lowest THD (2.29%) and DFIG with 3-winding transformer has greatest potency (above 93%).
