elektrivarustussüsteemidesse
An elektrivarustussüsteem (electrical supply system) is a network designed to deliver electrical energy from power generation sources to end-users. These systems are fundamental to modern society, powering homes, businesses, and industries. They typically consist of several interconnected components. Generation involves the production of electricity, usually at large power plants using various energy sources like fossil fuels, nuclear, hydroelectric, wind, or solar power. The electricity is then transmitted over long distances at high voltages through a network of transmission lines and substations to reduce voltage for distribution. Distribution networks then carry the electricity at lower voltages to individual consumers. Key elements within these systems include transformers, which change voltage levels, circuit breakers and switches for protection and control, and protective relays that detect faults and isolate affected sections of the network. Reliability and stability are paramount, achieved through redundancy, careful planning, and advanced control systems to prevent blackouts and ensure a continuous power supply. Modern elektrivarustussüsteemidesse are increasingly incorporating smart grid technologies to enhance efficiency, integrate renewable energy sources, and improve responsiveness to changing demand.
