Emulating Subsynchronous Resonance using Hardware and Software Implementation

Abstract

In this paper, the subsynchronous resonance (SSR) is investigated using LabViewand Matlab/Simulink based on the Simscape Power Systems tool. The simulation model in this paper is designed to identify, characterize and mitigate low frequency oscillations in power systems. The results obtained verify the effect of series compensation level on subsynchronous frequencies. The research in this paper represents the results of emulating SSR using hardware and software implementation. It then describes subsynchronous resonance studies that should be performed for each series compensation level. Technical descriptions and implementation model are provided.
