Abstract
In this paper enhanced multi-criteria-based passive islanding detection scheme is presented. Multi-criteria based islanding detection is based on measuring the change of voltage unbalance and voltage total harmonic distortion of all phase-to-phase voltages which are also multiplied by voltage sequence components dependent value. In this new scheme islanding verification logic is further improved, so that it can separate real islanding (healthy island i.e. no fault in the islanded part of the network) case from all the other network disturbances more reliably including also cases where islanding happens after fault in HV or MV network. Also the effect of recent grid code requirements as well as change in voltage positive sequence angle has been considered and taken into account in the proposed islanding detection scheme with improved islanding verification logic.
