New Relay Protection Methods for Lines
This paper describes a new line protection scheme suitable for systems with a high penetration of renewable sources. Engineering use: Protection engineers use distance, differential, directional overcurrent, pilot, and backup schemes to. SEL line protection solutions are ideal for improving system stability and security, allowing you to: Locate faults faster and more precisely with the traveling-wave technology in select SEL transmission relays. Launched by a fault, TWs are surges of electricity that propagate, reflect, and transmit throughout the network at nearly the speed of light. They monitor current, voltage, and frequency in real-time, triggering automatic disconnection of faulty sect...
