Co-Ordination Of Static Var Compenstors With Long Distance Radial Transmission System For Damping Improvement

The capability of static VAR compensators to use supplementary signals for damping improvements has been studied. Damping is shown to be a function of the transmission system loading and a function of the static VAR compensator. The study offers insights as to how static VAR compensators should be co-ordinated with respect to the transmission system. The technology under study is based on thyristor controlled reactor with switched capacitors. Only equal line sections are treated.
