Kotian, S.M.Shubhanga, K.N.2026-02-062018Proceedings of 2018 IEEE International Conference on Power, Instrumentation, Control and Computing, PICC 2018, 2018, Vol., , p. 1-6https://doi.org/10.1109/PICC.2018.8384779https://idr.nitk.ac.in/handle/123456789/31460In this paper, using a dynamic phasor model of static VAR compensator (SVC) a method to determine the phase response of a system analytically is presented. Then using the phase compensation method a subsynchronous damping controller (SSDC) for SVC is designed to mitigate subsynchronous resonance (SSR) in series capacitor compensated power systems. The designed SSDC is validated using detailed time-domain simulations in PSCAD/EMTDC. The case studies are carried out on the IEEE first benchmark system. © 2018 IEEE.Dynamic phasorEigenvalue analysisstatic VAR compensator (SVC)Subsynchronous damping controller (SSDC)Subsynchronous resonance (SSR)
