Sažetak
The paper analyzes the problem of long transmission lines drive and the possibility of applying of capacitive series compensation. It deals with the voltage on the lines and the influence of the degree of compensation to the transmission capacity and the stability of the steady state network voltage. The first aspect of the analysis is the problem of increased transmission line load when there is a necessity to relieve the load from the reactive power in order to convey as much real power through the line, reduce losses and maintain voltage within limits. Another aspect of the analysis is very small load or idle line, when the Ferranti effect leads to an extremely high voltage at the end of the line.
