Title: Innovations of Xiaobo Duan in Anti-Islanding Technology
Introduction
Xiaobo Duan is a notable inventor based in Hebei, China. He has made significant contributions to the field of electrical engineering, particularly in the area of distributed generation systems. His innovative work focuses on enhancing the safety and reliability of direct current distribution grids.
Latest Patents
Xiaobo Duan holds a patent for an "Anti-islanding method for distributed generator in direct current distribution grid and anti-islanding device therefor." This invention provides a method that includes feeding an alternating voltage component into an output end of the AC/DC interface transverter. The frequency of the 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 a first effective value of an alternating signal included in the first voltage signal, and comparing this value 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.
