Intelligent lengthways interconnected feeder line automatic control method

Abstract

The invention discloses an intelligent lengthways interconnected feeder line automatic control method for realizing easy fault location and zero-time power failure of a power-side non-fault region. The intelligent lengthways interconnected feeder line automatic control method specifically comprises steps of feeder line fault location, fault region isolation, power restoration of a load-side non-fault region and intelligent distributed emergency treatment considering transient fault. Information interaction is realized through an efficient lengthways communication protocol and adjacent intelligent distribution type distribution terminals in the same power supply topology network; the intelligent distribution type distribution terminal performs an intelligent lengthways interconnected feeder line automatic technology for overall treatment and logic judgment, so that a zero-time power failure function of the power-side non-fault region is realized, feeder line fault location can be carried out conveniently, the power supply reliability is improved efficiently, and the power failure time is shortened.

Description

technical field [0001] The invention relates to a feeder automation control method, which belongs to the technical field of power distribution automation.
