Question

A review on subsynchronous resonance and its mitigation techniques in dfig based wind farms

Answer 1

This may help,

The SubSynchronous Resonance (SSR) may occur in an induction generator based wind farms connected to the power system consisting of series compensated transmission line. The SSR in Doubly Fed Induction Generator (DFIG) based wind power generation is of more interest in recent years after a real-time event occurred at the Electric Reliability Council of Texas (ERCOT) grid. In this paper, we present a review on the analysis of SSR and its mitigation concerned to the DFIG based wind farms. This paper focuses the review on the analysis of SSR characteristics at different operating conditions, mitigation of SSR using supplementary damping controllers with FACTS devices and converter controllers in DFIG based wind farms.
