As demand for electricity increases, utilities around the world are adding capacity by increasing generation. This additional generation is becoming more decentralized with the incorporation of co-generators, independent power producers and alternative energy sources such as wind and solar. The interconnectedness of the electrical grid is necessary to provide redundancy and improved reliability. As the energy requirement of the customer base increases, more generation is added and the fault current levels in the existing grid rise dramatically. This puts undue strain on the infrastructure and increases the threat of potential outages.
According to the Electric Power Research Institute (EPRI), “Under increased power flow conditions on existing assets, managing fault currents is crucial in order to avoid malfunctioning and damage of equipment as well as to increase system reliability.”
SOLUTION FOR MANAGING
Applied’s FCLs use state-of-the-art technology and a
modular design approach to allow easy configuration.
Applied Materials has two solutions addressing
different segments of the grid market:
Superconducting FCL (SCFCL) using
superconductors for high voltages from
11kV to 400kV
Solid State FCL (SSFCL) using solid state
electronics for voltages from 6kV to 45kV
Both FCLs work with normal currents ~3500Amps
and are capable of handling faults exceeding 100kA.
