“…The power system network consists of a 138‐kV, 60‐Hz six‐phase transmission line of 68‐km length, connected to source at sending end and a source and two loads of 250 MW and 100 MVAr at receiving end. The six‐phase transmission line has been designed and modeled referring to the Springdale‐McCalmont 138‐kV, 60‐Hz three‐phase double circuit line of Allegheny Power System. The six‐phase transmission line model is simulated using simulink and simpowersystem toolbox of MATLAB.…”

SUMMARYIn this paper, modular concept of artificial neural network (ANN)-based technique is introduced to identify and locate all type of shunt faults (120) in a six-phase transmission line. The proposed algorithm is composed of two stages. In the first stage, ANN-based algorithm has been developed to detect and classify all possible types of shunt faults within one cycle time. Then, the second stage dispenses the location of shunt faults. Total 11 numbers of modular ANNs have been developed in both the stages which are based on the fundamental components of voltage and current signals at the sending end of transmission line only. For validation of the proposed scheme, simulation studies have been carried out on a six-phase transmission system. The test results of ANN-based fault detector/classifier and locator indicate that the proposed algorithm correctly detects/classifies and locates the shunt faults. The results demonstrate high speed, reliability and suitability of the proposed technique and its adaptability to changing system conditions viz. fault type, fault inception angle, fault location, high fault resistance, short circuit capacity of source and its X/R ratio. Even the cases of slight variations in system frequency, generated voltage and initial power flow angle are also taken into account.

“…Among the multiphase transmission line, six-phase transmission is the most promising alternative for transferring more power with the existing structure of a three-phase double circuit line. Preliminary works on the design and implementation [1][2][3][4][5][6][7][8][9] have disclosed the feasibility of a six-phase transmission line.…”
