Sub-synchronous control interaction (SSCI) is the interaction between the power electronics control and the series compensated transmission system that occurs at frequencies below the system nominal frequency. SSCI may occur between the doubly-fed induction generator (DFIG) control system and the series compensated transmission line, to which the wind park (WP) is connected. DFIG control system is not only parameters, but also the WP operating conditions have significant impact on SSCI. In this paper the impact of WP operating conditions and DFIG control system parameters on SSCI are analyzed in details.. This paper also examines the accuracies of various analytical tools used for SSCI problem identification and proposes a new frequency scan analysis approach for accurate prediction of potential SSCI problems
