AN APPROACH FOR MITIGATING COMMUTATION FAILURE USING CAPACITOR COMMUTATED CONVERTER IN HVDC SYSTEM

Abstract

With the growing demand of electricity on a daily basis, we cannot rely on conventional electric authority
systems like long-haul distributed power stations as well as complicated and heavy load / distribution networks. High
voltage direct current (HVDC) transmission networks contain an enormously essential role in authority methods.
Lacking the suitable study of the HVDC mechanism, it is impractical to attain an exact arithmetical model of the method
and in the lack of proper modeling the influence transmitted in the HVDC system cannot be measured. The power
transmitted through the HVDC system depends upon the competence of the controller and the converter station. A
Capacitor-Commutated Converter (CCC) on the basis of HVDC method is projected in this study. Along with this, to
regain the signals from distortion, the filter is applied to the distorted signals. Further, the simulation results evinces that
the developed system surpasses the results of traditional HVDC system in terms of commutation failure mitigation.
