Small signal analysis of Sub-synchronous resonance In DFIG

Sub-synchronous resonance (SSR) analysis model of a DFIG-based series compensated wind farm using Eigenvalue method.

SSR analysis based on the eigenvalue method is the most important among the used methods. Previously, the initial values of the state variables were calculated based on the iterative approach which is suffering from convergence problem, and lacking accuracy. Accurate and simple recent analytical approach is applied for SSR analysis based on the eigenvalue method.
