Course Description

Electrical power systems are large interconnected networks designed to generate, transmit, and distribute electrical energy to consumers. These systems typically consist of three major stages: generation, transmission, and distribution. Electricity is initially produced at power plants using various energy sources such as thermal energy, hydroelectric power, wind, solar energy, or nuclear power. However, the voltage generated at power plants is usually not suitable for long-distance transmission. To efficiently move electricity across large distances, voltage levels must be increased significantly. This is accomplished using step-up transformers in substations located near generation facilities. Once the electricity reaches major load centers, additional substations reduce the voltage to safer and more practical levels suitable for distribution networks and final consumption by residential, commercial, and industrial users. Substations therefore act as intermediate control points that ensure the safe and efficient movement of electrical energy throughout the entire power network.
