Qui "islanding" compare varie volte:
"The present invention relates to detection of a single-phase islanding condition in a three-phase electricity network. [0002] Distributed energy resource units, like solar cells or wind turbines, connected to a common electricity network provide in this electricity network islands, i.e. parts of the common electricity network, which are provided with power generation of their own. A single-phase islanding condition is a partial loss-of-mains situation in which a single phase of an electricity network incorporating power generation loses connection with the rest of the common electricity network. It is important to detect a single-phase islanding condition since it causes a safety hazard within the electricity network partially separated from the common electricity network."

Anche qui:
"There are several known methods for singlephase islanding detection in a three-phase electricity network. A known method for single-phase islanding detection comprises adding a low frequency stimulus reference signal into a reactive current reference of a frequency converter supplying the electricity network, and comparing a rate of change of network frequency with a normal value of the rate of change, wherein a single-phase islanding condition increases the rate of change of network frequency. An example is described in "Current injection for active islanding detection of electronically-interfaced distributed resources" (IEEE TRANSACTIONS ON POWER DELIVERY, vol. 21, 2006). "Negative-Sequence Current Injection for Fast Islanding Detection of a Distributed Resource Unit" (IEEE TRANSACTIONS ON POWER ELECTRONICS, vol. 23, 2008) describes a method for islanding detection based on negative-sequence current injection and detection. [0004] Known methods for single-phase islanding detection increase harmonic distortion in the electricity network and/or detect a single-phase islanding condition slowly."
