摘要

The majority of transmission system development is easily affected to several temporary and permanent faults due to transients and short circuits. These faults can destroy the transmission network internally and can lead to power system instability. It is necessary to clear these faults within the permissible operating time and have high degree of reliability and security for protective systems. This paper deals about wavelet-based protection scheme for SVC compensated multi-terminal transmission system in presence of hybrid generation. Fault indices are determined by detailed coefficients of current signals at all three terminals using Bior 1.5 mother wavelet. To discriminate the fault on the transmission system, fault indices are compared with a threshold value. The proposed algorithm is found to be reliable, accurate and fast as compared to conventional methods for different types of faults on SVC compensated multi-terminal transmission system with hybrid generation at various terminal locations and fault inception angles.
