A Concise Presentation of Doubly Fed Induction Generator Wind Energy Conversion Systems Challenges and Solutions

Abstract

There is increased worldwide wind power generation, a large percentage of which is grid connected. The doubly fed induction generator (DFIG) wind energy conversion system (WECS) has many merits and, as a result, large numbers have been installed to date. The DFIG WECS operation, under both steady state and fault conditions, is of great interest since it impacts on grid performance. This review paper presents a condensed look at the various applied solutions to the challenges of the DFIG WECS including maximum power point tracking, common mode voltages, subsynchronous resonance, losses, modulation, power quality, and faults both internal and from the grid. It also looks at approaches used to meet the increasingly stringent grid codes requirements for the DFIG WECS to not only ride through faults but also provide voltage support. These are aspects of the DFIG WECS that are critical for system operators and prospective investors and can also serve as an introduction for new entrants into this area of study.

STATCOM Controller Tuning to Enhance LVRT Capability of Grid-Connected Wind Power Generating Plants

“…where v and i denote voltage and current, respectively, R is the resistance (Ω), Ψ is the flux linkage (V s ), ω e is the supply angular frequency (rad/sec), and ω r is the rotor angular frequency (rad/sec) [26,27].…”

Desain dan Simulasi Double Field Induction Generator (DFIG) dengan Software MATLAB

“…Untuk merealisasikan potensi ini, maka diperlukan berbagai rumusan -rumusan teknis dalam pembangunan pembangkit listrik tenaga angin secara efektif dan efisien. Meskipun tenaga angin sebagai prime mover yang memiliki sifat intermitten dan uncertainty [2].…”

“…DFIG adalah sistem yang digunakan untuk mengatur arus rotor untuk mencapai variable yang diperlukan guna mendapatkan energi maksimum dalam konversi tenaga angin (wind energy). Keuntungan adanya DFIG ialah dapat mengatur kecepatan generator, pengaturan decouple daya aktif dan daya reaktif, noise dapat dinimalisir, dan kualitas daya bisa meningkatkan [2]. Secara konstruksi DFIG wind energy conversion systems (WECS) terdiri dari sistem wind turbine yang terkoneksi dengan gearbox maksud meningkatkan daya mekanik dari aliran udara dan konversi ke elektrik [3].…”
