Time-domain link technology for digital substations



 

SEL announces the release of a digital substation solution engineered with simplicity in mind – TiDL technology. In a TiDL solution, field modules are placed in the yard close to the primary equipment to digitise discrete I/O signals and analogue data, and then transport them over a fibre-optic cable to a relay in the control house. Replacing copper wires with fiber-optic cables increases personnel safety and improves system reliability. This innovative technology uses point-to-point connections and a non-routable protocol, providing a simple and secure solution; does not need an external time source or Ethernet switches, making it easy to implement with no network engineering required; combines the proven protection of the SEL-400 series relays with the modularity of the SEL-2240 Axion, reducing training requirements and providing a scalable and flexible solution; and provides built-in time synchronisation and synchronous sampling, ensuring protection is available in the relay regardless of whether or not an external time signal is available.
