Island monitoring method for power supply of new energy

The invention provides an island monitoring method for power supply of new energy, and belongs to the field of power supply detection. The island monitoring method for power supply of new energy includes the steps: acquiring the output voltage of a distribution transformer from a distribution table area summary table, and acquiring the voltage of a new energy input terminal from an input terminalsmart electric meter; and acquiring the voltage difference value between the output voltage and the voltage of the input terminal at the current moment, and if the difference value is less than a preset threshold, obtaining the voltage difference value corresponding to the previous moment, of the current moment to complete determination of island. By judging the existing power consumption information, the island monitoring method for power supply of new energy can complete judgment on whether an island effect exists, and can improve the responding speed of island judgment of power supply of new energy by setting the t
