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

Chin-Hsing Cheng,Yuan-Yih Hsu +1 more
TL;DR: In this article, the design of a static voltampere reactive (VAr) controller using a novel adaptive scheme is investigated, which makes use of self-tuning proportional-integral-derivative (PID) control, can provide better damping characteristics than a fixed-gain PID control SVC over a wide range of operating conditions.

Transient reactance effects in static shunt reactive compensators for long ac lines
TL;DR: In this paper, a simple equation derived from two calculable border cases and the asymptotic limits of a symmetrical multi-section transmission line is discussed in the light of experience gained from model studies on stabilisation of power transmission over distances exceeding 600 miles at 60Hz using saturated reactors.
