Existing modes of feeder automation (FA) are compared and analyzed first

and a method of intelligent distributed FA based on the directional node configuring method and generic object oriented substation event (GOOSE) high speed communication mechanism is proposed

which not only meets the demand of active distribution network

but also reduces the dependence on communication information between terminals during fault handling by means of the power direction protection element and the intelligent distributed peer-to-peer communication characteristics. Furthermore

a backup processing mechanism for channel failure with the capability of avoiding the override trip as much as possible is also proposed. A new type of power distribution terminal device is developed based on the above-mentioned intelligent distributed FA device with the capability of quickly realizing fault location

fault isolation and fault recovery is proposed using a dual-core CPU hardware platform and by referring to the standard modeling technology based on IEC 61850 and the high speed information sharing technology based on GOOSE. The device is currently in operation in several key projects in China.
