| Abstract: | Analysis is given of grid PV inverters in the safety protection, as well principle of islanding detection method analyzed in detail, a combined scheme is proposed of the over/under-voltage, over/under- frequency of the passive form islanding detection and the phase shifting one, using DSP as numerical control leading to the big simplification of realizing the inverter islanding detection, which is completed on DSP control including the island protect electric circuit and software design, experimental results show that rapid, reliable islanding detection scheme in this dissertation brings out the maximum detection time required being far less than the international standards, the Non-detection Zone is very small, ensure system under an safe and efficient operation. |
