Protection Based On Communication Application In Feeder Automation

Feeder Automation is important for Distribution Automation to the improvement of reliable electric energy. The advantages and disadvantages of many techniques of feeder automation are compared, and a new protective scheme is advanced, The main contents of the thesis are shown as follows:Many control modes of Feeder Automation are compared, the advantages and disadvantages of tradition feeder control mode are analyzed, the best control mode of Feeder Automation is put forward: protection based on communication.The work theory of protection based on communication and its backup protection is introduced in this thesis. Fault-recognizing and fault-separating can be done swiftly, so the system owns an excellent foreground.In some distribution network which has no communication, a scheme which uses the user subsection switch to deal with the fault is put forward.
