Abstract
The present invention is concerned with a fault current enhancement for triggering a protection device, such as a fuse or circuit breaker or protection relay used in protecting a distribution line of a power distribution network in an efficient and economical way. An Induction Machine (IM) is operated in parallel with an energy source connected to the distribution line via a Power Electronics (PE) interface, to provide a fault current characteristic of the composite PE interface and IM similar to that of a synchronous generator. Comparable fault currents enable a same protection device to be provided for protecting the distribution line irrespective of a kind of interface used to source energy to the distribution line.
