Generation transmission and distribution of electric power 1 introduction in this lesson a brief idea of a modern power system is outlined emphasis is given to create a clear mental picture of a power system to a beginner of the course electrical technology as consumers we use electricity for various purposes such as 1. The most important activity performed by the power sectors are power generation transmission and distribution electricity is generated at different power stations then it is transmitted through various channels like power transformers transmission lines and transmission substations to the distribution substations finally distribution . Electric power transmission is the bulk movement of electrical energy from a generating site such as a power plant to an electrical substationthe interconnected lines which facilitate this movement are known as a transmission networkthis is distinct from the local wiring between high voltage substations and customers which is typically referred to as electric power distribution. Each is organized into topical parts and chapters in an attempt to provide comprehensive coverage of the generation transformation transmission distribu tion and utilization of electric power and energy as well as the modeling analysis planning design monitoring and control of electric power systems
