L. Angquist et al., POWER OSCILLATION DAMPING USING CONTROLLED REACTIVE POWER COMPENSATION - A COMPARISON BETWEEN SERIES AND SHUNT APPROACHES, IEEE transactions on power systems, 8(2), 1993, pp. 687-700
The paper describes how controlled reactive power compensation can be
used to damp power systems oscillations. This is of particular interes
t in the case of weakly coupled networks. A comparison is made between
two kinds of controllable reactive power elements, namely the CSC (Co
ntrolled Series Capacitor) and the SVC (Static Var Compensator). The e
ssential topics dealt with are efficiency in terms of ''damping effect
'' per installed Mvar and the dependence of equipment location. Also t
he influence of connected loads is investigated to some extent. Basic
relationships for the CSC and the SVC approaches are shown in appendic
es.
