Long distance transmission line with controlled shunt reactors (CSRT)

Abstract

In this paper the power transmission line from hydro-power station at rapids of the river Congo to Egypt (4500 km) is considered. It is shown that the main problem of the electric energy transmission over long line is connected with a compensation of surplus reactive power of line. Three different variants for this line are presented in this paper with regulated shunt compensation in accordance with transmitted power over the line. For this purpose controlled shunt reactors of a transformer type (CSRT) are used. A mode of voltage by any transmitted power over the line is considered - from no load to natural mode of transmitted power.
