Power System Stabilizers

Power System Stabilizers (PSS) are control devices used in electrical power plants to improve stability and prevent power swings or blackouts. They detect fluctuations in the electrical grid and send signals to the generator's control system to adjust its output. By damping oscillations caused by changing demand or disturbances, PSS helps keep the electricity supply steady and reliable. Essentially, they act like shock absorbers, ensuring the power system remains balanced and stable during normal operation and unexpected events.
