An Advanced Simulation Model for VSC HVDC Transmission

Abstract

The research of this simulated project is based on the hybrid simulation model for the voltage source converter high voltage direct current (VSC HVDC). This research main aim is based on the needs to implement new methods and tools for obtaining the required information to evaluate the mutual influence of HVDC and HVAC systems. This research presents important topics like commutation process, hybrid simulation for the advanced modeling of VSC HVDC. The simulation results obtained from this research by the prototype of specialized hybrid processor of VSC HVDC model confirms the amount of harmonics, efficiency and effectiveness of the approach with the help of the detailed representation of commutation process by using power semiconductor devices and simulation in VSC and EPS without any limitation on their duration.

This research also provides the extension of simulation results to one more level. Actually, the simulation results of this research are that the phase to phase voltage of VSC HVDC is a three level result. But this three level simulation result is extended to five level simulation result which can be concluded at the end of the project.
