Development of a Damping Model for Subsynchronous Resonance in a Doubly Fed Induction Generator Based Wind Farm

Abstract

Increases in the level of series compensation on the transmission line used to connect a Doubly Fed Induction Generator (DFIG)-based wind farm to the grid lead to the occurrence of subsynchronous resonance (SSR) conditions. SSR causes system instability and an increase in oscillations. To address these issues, this study aims to develop a damping model in the rotor-side converter (RSC). The proposed model for the DFIG is designed based on the d–q axis inner current control loop. Using the damping model developed in the RSC, SSR conditions under different series compensation levels and varying wind speeds are investigated. The results show that the damping model developed based on the d–q axis inner current control loop provides effective performance in terms of stability enhancement and oscillation damping under different operating conditions.

Çift Beslemeli Asenkron Generatör Tabanlı Rüzgar Çiftliğinde Alt-Senkron Rezonans için Sönümleme Modelinin Geliştirilmesi

Abstract

Çift Beslemeli Asenkron Generatör (ÇBAG) tabanlı rüzgar çiftliğinin şebekeye bağlantısında kullanılan iletim hattı üzerinde seri kompanzasyon oranındaki artışlar Alt-Senkron Rezonans (SSR) durumlarına sebep olmaktadır. SSR sistemde kararsızlık ve salınım artması durumlarını ortaya çıkarmaktadır. Bu problemlerin çözümlenmesi için bu çalışmada Rotor Tarafındaki Evirici (RSC) devresinde sönümleme modelin geliştirilmesi amaçlanmaktadır. ÇBAG’da geliştirilmesi amaçlanan bu model d-q eksen iç akım döngüsü temelli olarak tasarlanmıştır. RSC devresinde geliştirilen model ile farklı seri kompanzasyon oranlarında ve farklı rüzgar hızlarındaki SSR durumları incelenmiştir. Yapılan çalışmada d-q eksen iç akım döngüsü temelli olarak geliştirilen sönümleme modelinin farklı çalışma koşullarında kararlılık ve salınımların sönümlenmesi açısından iyi sonuçlar verdiği görülmüştür.
