Wavelet Transform Based Fault Classification and Location in DPFC Compensated Transmission

Abstract

In the present power system scenario, transmission system is very complex and plays on vital role to transmit power from generating station to distribution system. For effective transmission of power, flexible AC transmission system (FACTS) is used in transmission line. Among the FACTS device, distributed power flow controller (DPFC) is the advanced and latest technology which is used in the transmission system for more effective transfer of power. To classify and locate the fault in the DPFC compensated transmission system is complex when compare to other FACTS devices. In order to classify and locate the fault in the transmission system, discrete wavelet transformer (DWT) tool is introduced. The classification and location of fault is carried out accurately and efficiently with the help of DWT coefficients for the given test system.
