Faulty Phase Identification for Transmission Line with Metal Oxide Varistor-protected Series Compensator

Mohammed Hussien Hassan Musa, Ling Fu, Zhengyou He, Yumin Lei
2021 Journal of Modern Power Systems and Clean Energy  
The accuracy of a conventional fault detection schemes is adversely affected by continuous change of the system impedance and load current at the point of a series compensation unit.  ...  Primarily, the fault feature is identified using the covariance coefficients of the current samples during the fault period and the current samples during the pre-fault period.  ...  Figure 15 shows the performance of the proposed scheme against the linear regression-based method [20] , which uses the difference between the current signal slopes of each sample recorded during the  ...
