A New Fault Identification Method for HVDC Transmission Line
Sherin Tom | Jaimol Thomas
Abstract: This paper presents a transient based fault identification for High Voltage Direct Current (HVDC) system. Characteristics of the HVDC system during internal and external fault are studied. Variation of transient energy and the relation between various parameters of the line are analyzed during each fault. Based on that the transient method is developed. Transient energy can be obtained by measuring the voltage and current at the two terminals of the line. Identification of internal fault and external fault can be done correctly and quickly from the calculated value of transient energy. The transient current can be analyzed to find out the type of internal and external fault. The test system is modeled in MATLAB - SIMULINK package based on CIGRE HVDC benchmark system.
