These relays play a crucial role in modern power systems. They effectively support the integration and incorporation of renewable energy sources such as wind and solar power by intelligently controlling and adjusting them to optimize their utilization. Additionally, these relays are equipped with functions such as real-time monitoring of grid status, remote control of power equipment, and data acquisition and analysis. They promptly identify and respond to various fault conditions, including short circuits, overloads, under-frequency, and over-frequency, thereby ensuring the safe and stable operation of the power system.
