| Abstract: | Islanding detection is a mandatory function for photovoltaic grid-connected inverter, and the islanding detection strategy decides the performance of the islanding detection. An islanding detection slip-mode frequency shift（SMS） method which was simple and easy to implement was described. This paper applied the SMS method to a 100 kW photovoltaie grid-connected inverter successfully for testing the anti-islanding capability. The islanding performance test shows that the SMS method can quickly and accurately detect the occurrence of island states. |
