This book includes my lecture notes for electrical power transmission course. The power transmission process, from generation to distribution is described and expressions for resistance, inductance and capacitance of high-voltage power transmission lines are developed used to determine the equivalent circuit of a three-phase transmission line.The book is divided to different learning outcomesPart 1— Describe the power transmission process, from generation to distribution.Part 2— Develop expressions for resistance, inductance and capacitance of high-voltage power transmission lines and determine the equivalent circuit of a three-phase transmission line.Part 1: Describe the power transmission process, from generation to distribution.Describe the components of an electrical power system.Identify types of power lines, standard voltages, and components of high-voltage transmission lines (HVTL).Describe the construction of a transmission line, galloping lines, corona effect, insulator pollution, and lightning strikes.Explain transmission system stability in regards to power transfer, power flow division, and transfer impedance.Part 2: Develop expressions for resistance, inductance and capacitance of high-voltage power transmission lines and determine the equivalent circuit of a three-phase transmission line.List the types of conductors used in power transmission line.Develop the expression for the inductance and capacitance of a simple, single-phase, two wire transmission line composed of solid round conductors.Deduce the expression for the inductance and capacitance of a simple, single-phase composite (stranded) conductor line.Derive the expression for the inductance and capacitance of three-phase lines having symmetrically and asymmetrically spacing and for bundled conductors.Discuss the effect of earth on the capacitance of three-phase transmission lines.Derive the short transmission lines models and medium transmission lines models.
