Comparative investigation on HVDC and HVAC for bulk power delivery
2021
Abstract A high voltage direct current (HVDC) is an efficient technology used to design and deliver a bulk amount of electricity over a long distance with negligible losses. When the time progresses simultaneously the load demand is also increasing, so there should be only two possibilities either to increase power generation or to minimize the losses, therefore, using HVDC can greatly reduce the power transmission losses. The cost is one of the most important factors, hence HVDC is a more suitable option for bulk power delivery as the total cost of the HVDC transmission system is very less as compared to that of a high voltage alternating current (HVAC) system transmitting the same amount of the electricity over the same distance. In this paper performance of HVDC under different load and faulty conditions is analyzed for various parameters under consideration with given constraints. Matlab Simulink is used for modeling the 12pulse HVDC transmission system. Results show that HVDC is the best option for bulk power transmission. A comparative analysis of HVDC and HVAC power transmission systems has also been done for its acceptability.
