This paper presents distribution generation (DG) different size and technology connecting to distribution networks in a system, and perturb associated with out-of phase reclosing operation, anti-islanding sustained to be an cause where no clear solution exists. This concept shows an auto ground approach that is proposed in the DG protection. An exemplification system is constructed by using the standard distribution apparatus and a recluse controller and the distributed generators were tripped through the high-speed communications circuit and were blocked from closing back it is tested on the utility‘s distribution test line model to a protection. The operation shows anti-islanding detection time is approximately a cycle longer than the delay associated with the application of the auto ground. Once the auto ground is applied, the DG is disconnected within 4 cycles on over current protection and applies to all DG types, the concept is inherently scalable, is confiscable to various reclosing operations and does not require additional equipment or setting changes at the producer‘s site, and reduces the cost of equipment.
