Method for Calculation Controlled Compensating Devices Parameters Extra High Voltage Power Lines

Abstract

One of the main elements of the power system is the extra high voltage transmission lines, which are systemforming for the bulk electric networks. The normal operation of the integrated power system depends on the reliability and efficiency of operation transmission line. To ensure efficient operation of the extra high voltage transmission line, it is necessary to optimize the voltage mode and reactive power. Optimization of the transmission line mode operation by minimizing the losses of active power in it, should be based on solving problems of optimization of voltage and reactive power. The control of the operating mode of the transmission line is the correct choice of the composition of the charging power compensation devices in order to regulate the voltage levels and power factors on the bus terminals. Optimization of the transmission line modes operation in this problem statement is performed, focusing on some of the most significant mode parameters. It should also be noted that previous studies have not addressed issues related to the corona discharge of wires and its impact on voltage distribution and the feasibility of depth regulation in lines of this voltage class. One of the measures to reduce electricity losses is to optimize the operating modes of transmission lines in terms of voltage and reactive power.
