MATLAB/SIMULINK Model For HVDC Fault Calculations

Power transmission has faced many challenges as the days goes by. Power demand has increased and its becoming increasingly difficult to acquire right way for new lines, due to growth, population, urbanizations and environmental issues. This research aims to provide methods for the rationale selections of HVDC system, essential HVDC equations and their control. A MATLAB/SIMULINK model is developed for a HVDC link using IGBT/DIODE converters between a 500KV, 50Hz system to a 330KV, 60Hz system over the distance of 450km. Analysis by using the model on this system identifies any abnormal behavior on the AC and DC sides and calculates the time elapsed for recovery to its reliable state conditions.
