Rapid Protection System Using Single-End Current Data for Capacitive Compensated Power Transmission Network

This paper presents a new approach based on current data processing and characteristic extraction method to detect the fault in a capacitive compensated power transmission network (CCPTN). The scheme uses the transform in the level of the three-phase currents at the local bus of the CCPTN for fault detection and the WIs (wavelet indices) for phase categorization. The functioning of the scheme is extensively authenticated on the 500 kV CCPTN using MATLAB software. The simulations show that the scheme is tremendously important for the CCPTN.
