Abstract

The invention relates to a CAN bus optical fiber internet + 10KV feeder line fault automatic processing system and method. A plurality of line breakers are arranged in a 10KV distribution line, each line breaker is connected with an intelligent terminal box, a voltage transformer is arranged between the intelligent terminal box and the distribution line, a lower computer and a CAN bus controller are arranged in each intelligent terminal box, each lower computer is connected with the upper computer through an optical fiber, the CAN bus controllers are connected through CAN bus optical fibers to form a protection system, and the lower computer in each intelligent terminal box is connected with the CAN bus controller. When a short-circuit fault occurs in a line, the CAN bus protection system quickly selects a fault point to cut off fault isolation; and power reconstruction is realized through once superposition of fault points or rapid recovery of power supply in a non-fault area through an optical fiber interconnection instruction of the upper computer and the lower computer.

Description

technical field [0001] The invention relates to a 10KV feeder automatic fault processing system and method, in particular to a CAN bus optical fiber Internet + 10KV feeder automatic fault processing system and method, which belongs to the technical field of power transmission and distribution. Background technique [0002] Feeder automation is the basis of distribution system automation. Distribution system automation includes five aspects: feeder automation, substation automation, power consumption automation, distribution management automation, and automated communication systems. [0003] Among them, the feeder automation is different from others. Its equipment is distributed in the distribution line, which can detect and locate the fault of the distribution line, automatically isolate the faulty section and restore the power supply to the non-faulty section. 10kv feeder automation is one of the first choices to improve power supply reliability. Power supply reliability ...
