Tehojärjestelmän

Tehojärjestelmän (power system) refers to the infrastructure and components that generate, transmit, distribute, and utilize electrical power. It is a critical component of modern society, enabling the delivery of electricity to homes, businesses, and industries. The power system consists of several key elements:

Generating stations produce electricity from various sources such as fossil fuels, nuclear energy, renewable sources like wind and solar, and hydroelectric power. These stations convert mechanical or chemical energy into electrical energy through generators.

Transmission lines carry electricity from generating stations to substations, often over long distances. These lines are designed to handle high voltages and large amounts of power, minimizing energy losses during transmission.

Substations receive electricity from transmission lines and step down the voltage to levels suitable for distribution. They also perform other functions such as switching, protecting, and controlling the flow of electricity.

Distribution lines deliver electricity from substations to end-users, such as residential, commercial, and industrial customers. These lines operate at lower voltages compared to transmission lines.

Power system components include transformers, circuit breakers, switches, and protective devices that ensure the reliable and safe operation of the system. They also include control systems that monitor and manage the flow of electricity.

The power system is designed to be reliable, efficient, and secure. It must be able to meet the demand for electricity at any given time, while also accommodating fluctuations in supply and demand. Power system operators and engineers work to maintain the stability and integrity of the system, ensuring that electricity is delivered to customers with minimal interruptions.
