摘要（英）：

The invention discloses a system and a method for testing self-adaptive current protection performance of a power distribution network, and relates to the technical field of power systems, aiming to improve comprehensiveness of protection performance testing of the power distribution network with a distributed energy resource. The system for testing the self-adaptive current protection performanceof the power distribution network comprises an operation mode controller and an equivalent power source. A power interface of the equivalent power source is connected with a first feeder line and a second feeder line. A first node of the second feeder line is connected with the distributed energy resource in an interruptable mode. A first segment of the second feeder line is connected with a first power distribution network self-adaptive current protection unit, and a second segment of the second feeder line is connected with a second power distribution network self-adaptive current protection unit. The first power distribution network self-adaptive current protection unit is connected with a shutting detector, an impedance detector and a motion detector. The system and the method are used for testing the self-adaptive current protection performance of the power distribution network.
