Modeling of electrical systems powered by generator sets for long railway tunnels
The paper describes and analyzes the electrical system of a long tunnel placed along the 'Naples-Bari' High-Speed railway line. In particular, a critical situation, due to a blackout event has been investigated. A generator set must guarantee the service continuity to supply safety and signaling system, emergency lighting and auxiliary equipment of electrical substations. A shunt reactor has been installed to compensate the reactive power produced by the long feeding cable and to respect the capability curve of the generator.
