Abstract : |
A simple and general method of determining the maximum efficiency of a transmission line is described. The method can be applied to both compensated and uncompensated lines. The maximum efficiency for a given load power factor and the power factor angle at which the highest value of the maximum efficiency occurs are determined from very simple analytical expressions. The method was tested on a 500 kV transmission line with several series and shunt compensation schemes. The influence of various factors such as the load power factor, line length and the degree of series and shunt compensations on the maximum efficiency was also investigated., |
