Latest Patents

Jie Guo holds a patent for an "Anti-islanding method for distributed generator in direct current distribution grid and anti-islanding device therefor." This patent outlines a method that includes feeding an alternating voltage component into the output end of the AC/DC interface transverter. The frequency of this alternating voltage component is less than the power frequency. The method involves sampling a first voltage signal from the output end of the DC/DC transverter, extracting the first effective value of an alternating signal included in that voltage signal, and comparing it with a preset voltage. If the first effective value is determined to be less than the preset voltage, the distributed generator is controlled to stop operation, indicating that islanding has occurred.
