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. © 2020 Elsevier B.V.
