In this paper, a novel technique for reactive power management of present and future Ultra High Voltage (UHV) lines having voltage level of 1200 kV line and above is suggested. The technique involves the use of three-phase UHV Transformers as a controlled shunt reactor (CSR) in combination with the use of fixed reactor. The system can be used for maintaining voltage profile, resulting in enhancement of the reliability of the UHV transmission system. The UHV power grid has to frequently face the problems associated with the power frequency over-voltages and switching over-voltage, the use of CSR is found to be effective in mitigating system problems. The performance of the UHV AC transmission line is studied using PSCAD software and working of CSR is evaluated. Standard parameters of the proposed Wardha-Aurangabad 1200 kV transmission line in India are considered for simulation model.
