World energy consumption rate is ascending consistently over the past few decades and it is expected to continue rising in the future. Researches on renewable energy sources have been carried out and ways to reduce energy consumption and energy wastage have been discussed and studied to tackle the world’s power shortage problems. Therefore, this project presents a comparison of power loss for various transmission systems. Two different transmission systems are analysed in this project; HVAC and HVDC. High Voltage Alternating Current (HVAC) transmission system and High Voltage Direct Current (HVDC) transmission systems are simulated in PSCAD software. The major components; transmission station, transformer and transmission line are investigated to evaluate their influence on the power loss. The cable length is also varied to analyse its effect in term of power loss on these two transmission systems. The experimental findings and analysis are presented in this project. The research presented in this project identifies the key sources of power loss while transmitting power from generator to load through HVAC and HVDC transmission systems. These findings will ultimately assist in accessing the design and analysis on economic feasibility of the transmission system.
