A Cumulative Standard Deviation Sum Based Method for High Resistance Fault Identification and Classification in Power Transmission Lines
High resistance fault poses an enormous challenge to the existing algorithms of fault detection and fault classification. In this paper
the standard deviation and accumulation method are employed to perform the fault detection and classification. It is primarily built in two stages. Firstly
the standard deviations for the measured current's signals of the local and remote terminals is computed to extract the fault feature. Secondly
the cumulative approach is used to enlarge the fault feature to perform the high resistance fault. The proposed scheme is known as Standard Deviation Index (SDI)
and it is obtained for the three phases and zero sequence. The proposed algorithm has been tested through different fault circumstances such as multiple faults locations
fault resistances
and fault inception time. Moreover
far-end faults with high-resistance
faults happened nearby the terminal
faults considering variable loading angle
sudden load change
different sampling frequency
bad signaling and a fault occurred in the presence of series compensation are also discussed. The results show that the proposed scheme performed remarkably well regarding the fault with resistance up to <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$1.5\Omega$ and can be detected within a millisecond after the fault inception. Additionally
the computational simplicity that characterizes the processes makes it more efficient and suitable for domain applications.
Abstract
High resistance fault poses an enormous challenge to the existing algorithms of fault detection and fault classification. In this paper
the standard deviation and accumulation method are employed to perform the fault detection and classification. It is primarily built in two stages. Firstly
the standard deviations for the measured current’s signals of the local and remote terminals is computed to extract the fault feature. Secondly
the cumulative approach is used to enlarge the fault feature to perform the high resistance fault. The proposed scheme is known as Standard Deviation Index (SDI)
and it is obtained for the three phases and zero sequence. The proposed algorithm has been tested through different fault circumstances such as multiple faults locations
fault resistances
and fault inception time. Moreover
far-end faults with high-resistance
faults happened nearby the terminal
faults considering variable loading angle
sudden load change
different sampling frequency
bad signaling and a fault occurred in the presence of series compensation are also discussed. The results show that the proposed scheme performed remarkably well regarding the fault with resistance up to 1.5kΩ and can be detected within a millisecond after the fault inception. Additionally
the computational simplicity that characterizes the processes makes it more efficient and suitable for domain applications.
