The Research of Islanding Detection about the Photovoltaic Grid-Connected Generation System

Zongjie Liu, Lifeng Zhu, Li Deng, Lijun Qin, and Feng Jiao
Abstract—The photovoltaic grid-connected generation system is rapidly developed and applied due to the cleaning, renewable and wide distribution of solar. This paper is to solve the problem about islanding detection brought by the photovoltaic grid-connected generation system. First of all, it analyses the reason happened and potential hazards of the Islanding and introduces the existing detection method and islanding detection. Then, in view of the insufficiency of the existing method, it put forward a new solution that combined the negative sequence voltage positive feedback voltage with active power positive feedback to the islanding detection. The amount of change of the frequency and the voltage is introduced to the voltage - active power positive feedback, which can effectively and fast detect the island.

Index Terms—Islanding detection, negative sequence positive feedback, photo voltaic grid-connected, voltage-active power positive feedback
