The invention relates to relay protection for an electric power system, aims to provide an adaptive setting method which calculates the real-time operation state of the back-side inversion-type distribution generation according to locally measured electrical information of protection and completes current protection accordingly, and can improve the selectivity and reliability of current protectionfor the distribution network containing the distributed generation without relying on communication. Therefore, the adaptive current protection setting method for the distribution network containingthe inversion-type distributed generation comprises the steps of obtaining the real-time voltage and current at the protection installation part, calculating an actual operating point of the distributed generation before the failure of the system according to set topological parameters of the distribution network and a control strategy of the distributed generation at the back side of the protection, and thus calculating the output current of the distributed generation when a short circuit fault occurs at the tail end of the protection range, thereby completing adaptive current protection setting taking output characteristics of the inversion-type distributed generation into consideration. The adaptive current protection setting method is mainly applied to current protection setting occasions.
