ACTIVE POWER LOSSES IN LONG LINES DURING COORDINATED, LIMITING AND MALFUNCTION BEHAVIOR

Abstract

Exact formulas for calculation of limiting values of transmitted capacity and efficiency of lines of a variable voltage with active loading on the reception end are resulted. Critical resistance and losses of capacity are determined depending on length Air-lines of an electricity transmission of a class of a voltage 500 … 750 kV. Emergency operation in the loaded electricity transmission is investigated.
