TL;DR: In this paper, a new concept is presented according to which a midpoint-located static VAR system with appropriate auxiliary control can be simultaneously employed for damping torsional oscillations and enhancing the steady state power transfer limit.

TL;DR: In this article, a new auxiliary signal designated as computed internal frequency (CIF) is proposed which synthesizes the frequency of the generator internal voltage from quantities available at the SVS bus and demonstrated that this signal is far superior to other conventional auxiliary signals in that it allows full utilization of the network transmission capacity.

TL;DR: In this paper, the influence of different levels of complexity in modelling various constituent subsystems on the dynamic stability of power systems compensated by static var systems (SVS) operating on pure voltage control is discussed.
Abstract: This paper is concerned with the influence of different levels of complexity in modelling various constituent subsystems on the dynamic stability of power systems compensated by static var systems (SVS) operating on pure voltage control. The system components investigated include thyristor controlled reactor (TCR) transients, SVS delays, network transients, the synchronous generator and automatic voltage regulator (AVR). An overall model is proposed which adequately describes the system performance for small signal perturbations. The SVS performance is validated through detailed nonlinear simulation on a physical simulator.
