摘要： An exemplary method comprises the steps of introducing a reactive current reference square wave, detecting load voltage changes at every change in the reactive current reverence wave, and determining whether the detected load voltage changes exceed a predefined islanding detection threshold value, indicating a loss of mains and an islanding operation of the power generator. With the exemplary loss-of-mains detection, islanding can be detected within a shortest period of time, even if the local islands active and reactive load matches exactly the distributed generators active and reactive power generation. So even without a sudden voltage change, unintentional islanding can immediately be detected and control electronics can safely turn of the distributed power generator.

A filtered transformer inductance voltage is formed by filtering a transformer inductance voltage, which is formed from the power supply system current, using a low-pass filter characteristic. A filtered power supply system voltage is formed by filtering a power supply system voltage using a low-pass filter characteristic. The regulating signal is formed by addition of a regulator voltage, the filtered transformer inductance voltage, and the filtered power supply system voltage, where the regulator voltage is formed by regulating the filtered power supply system current at a power supply system current nominal value.
