Screening Studies for Susceptibility to Sub Synchronous Control Interaction using EMTP848

Abstract
Sub Synchronous Control Interaction (SSCI) is can occur between type 3 wind turbines and a series capacitor. SSCI events can result in severe overvoltages that can damage equipment on the transmission... see more system. This presentation will provide a brief history of SSCI, its impacts on the power system, and how to perform screening studies for SSCI susceptibility using EMTP… The presentation will also include a discussion of challenges encountered, and key results observed, during screening studies performed by IEEE working group J18 for an example power system. Areas of future study will also be highlighted.
