PSS (Power System Stabilizer)
A Power System Stabilizer (PSS) is a device that helps keep an electrical power grid stable. It works by sensing changes in the system's vibration or oscillations, which can cause fluctuations in power flow. The PSS then sends signals to control equipment, like generators, to reduce these oscillations quickly. This helps prevent power outages, equipment damage, and maintains consistent electricity supply, especially during disturbances or heavy demand. In essence, the PSS acts as a stabilizer, ensuring the grid remains steady, reliable, and efficient.
