TLDR
In this article, the static compensator and the excitation system control parameters are chosen in a coordinated manner from the stability limit plots, the extension of stability limits with a Static Compensator are quantised, later a second compensator is included for improving the system performance.Abstract:
This paper deals with the dynamic stability of long distance a.c. transmission systems operating at above 1 surge impedance loading and compensated entirely by automatically controlled shunt inductance device referred to as Static Compensators. Generalised system equations in the form X = AX, with a careful choice of state variables are developed via the subsystem concept and the eigenvalue technique used to establish the stability limits. The static compensator and the excitation system control parameters are chosen in a coordinated manner from the stability limit plots, the extension of stability limits with a Static Compensator are quantised, later a second compensator is included for improving the system performance and interaction studies.read more

Static var system auxiliary controllers for transient stability improvement of power systems
Narendra Kumar,M. P. Dave +1 more
TL;DR: In this paper, a comparative performance evaluation of SVS auxiliary controllers for transient stability enhancement of long transmission lines over a wide operating range is presented, where the SVS has been considered located at the middle of the transmission line.

Nonlinear Control of Static Var Systems
TL;DR: The primary function of SVS is to maintain a substantially constant voltage of its installed bus by generating or absorbing the required amount of reactive power, which also benefits to the reactive power balance of the power system.
