摘要：
In order to solve the problem that the traditional detection method is difficult to set the threshold and has great influence on power quality，a hybrid islanding detection method based on the combination of resistance change rate and active power disturbance is proposed. As a passive method，the resistance change rate can respond quickly after islanding, and the active power disturbance module is turned on only when the passive method suspects islanding，and the minimum active power that can make the voltage of the common coupling point exceed the limit is injected adaptively. The simulation results show that this method can quickly and correctly detect the islanding effect，and there will be no misjudgment even in the case of non-islanding. © 2024 Science Press.
