Modeling of Voltage Source Converter based HVDC system in EMTP-RV

Abstract

This paper presents a detailed model of a Voltage Source Converter (VSC) operated HVDC transmission system, simulated with EMTP-RV package, in order to investigate its operational performance. The VSC control strategy is explained using vector control. The effect of de-coupling between the control parameters is investigated by applying disturbances in the reference quantities of active and reactive power and DC voltage. The simulation results provided validate the vector control strategy for independent control of system parameters.
