Abstract
Nowadays, due to the ever-increasing global energy demand and the complex option for an individual to install renewable power generation at his/her residence, it has become imperative to operate power plants that deliver energy to transmission and distribution systems at a reduced power loss and at the same time maximize efficiency. Therefore, the need arises to construct cost-effective high transmission lines considered at Extra High Voltage (EHV) levels. In this study, the mechanical structures and electrical line parameters of a 750-kV single-circuit 4 conductors per bundle based on existing standards were designed. These EHV levels are then analyzed and the results obtained are compared with the 330kV lower voltage levels in order to extract the benefits. The implementation of the designed 750-kV grid in the Nigeria transmission system results in a significant reduction in the systems’ power losses in comparison to the existing 330-kV system.
