Performance Analysis of Bipolar based HVDC and AC System for Ethiopia -Kenya

Abstract

Electrical power can be generated from renewable and non-renewable energy sources in the world. Ethiopia blessed by renewable energy sources in the East Africa. Ethiopia Electrical Power Corporation has been constructed huge clean renewable Energy for national as well as for neighboring countries. The potential to generate electric power from only hydro plant is 45,000 MW in Ethiopia. Currently generated power transmission takes place by High Voltage Alternate Current (HVAC) overhead systems to inside and outside of Ethiopia. This paper is to develop high voltage direct current (HVDC) technologies instead of HVAC system from Wolayta Sodo at Ethiopian side Suswa at Kenyan side. This HVDC link between Wolayta Sodo and Suswa, consisting of about 1,045 km of high voltage direct current ±500 kV, 2000MW capacity. The intention of this work is to develop bipolar HVDC overhead system and analyze the system performance with and without fault in AC side can be carried out using MATLAB/Simulink.
