“…To overcome this problem, a new method was proposed, by using the Current alpha and beta (Current mode) from the Clarke's transformation to convert the signal. Then, discrete wavelet transform (DWT) is used to obtain wavelet transform coefficients (WTC) 2 , to determine the current time when the fault amplitude values (WTC 2 would reach a maximum point, to determine the fault location distance. This paper also proposed algorithm fault classification by using Clarke's transformation.…”

This paper proposed a new algorithm for fault location and classification using wavelet based on Clarke's transformation to obtain the fault current. This novel method of fault current approach is studied by comparing the use of the glide path of the fault voltage. The current alpha and beta (Current Mode) were used to transform the signal using discrete wavelet transform (DWT). The fault location was determined by using the Clarke's transformation, and then turned into a wavelet, which was very precise and thorough. The most accurate was the mother wavelet Db4 which had the fastest time and smallest error detection when compared with the other wavelet mothers. In this study, the Clarke's transformation is also compared with the Karenbauer's, which has produced results with similar error percentage. The simulation results using PSCAD / EMTDC software showed that the proposed algorithm could distinguish internal and external faults to get the current signal in the transformation of a signal fault.

“…It is well known that one-end methods are more attractive compared to two-end methods as it does not require synchronized measurement at both terminals and communication between the terminals. Some methods employ the simplified short line model neglecting shunt capacitances [14,20,22,25]. This will, however, affect the accuracy of fault location for long lines.…”

A fault location algorithm without synchronization for double‐circuit transmission lines does not require sampling synchronization, reduces the cost, and has a higher engineering value, but the algorithm still needs to be improved in the false‐root identification. This paper conducts further studies on this issue. First, the false‐root problem of the fault location algorithm without synchronization is analyzed, and then a new false‐root identification method is proposed, which is based on the difference of the existence of the false root in the calculation of the voltage amplitude along the line with different electrical moduli. It can solve the problem of the traditional method, which cannot distinguish between voltage amplitudes when they are close. Second, considering the shortcoming of the existing phase‐mode transformation matrix, a new phase‐mode transformation matrix applied to double‐circuit lines is deduced, which is based on the six‐sequence component method; it can be combined with the new false‐root identification method, thereby realizing false‐root identification under various types of faults. Finally, fault location is realized by using the moduli in the mold domain. The principle does not need to synchronize data in two terminals and is not affected by the fault types, fault resistances, and other factors. As is shown in a large number of Alternative Transients Program version of Electro‐Magnetic Transients Program (ATP‐EMTP) simulation results, the fault location has a higher accuracy © 2017 Institute of Electrical Engineers of Japan.
