PROTECTION COORDINATION USING ZONE SELECTIVE INTERLOCKING METHOD AND NEURAL NETWORK IN IEEE 9 BUS PLAN

摘要

Ring distribution network system has a complex problem. Besides that, the addition of distributed generators (Distributed Generation) would make the changes in network topology configurations and affected the value of short-circuit current that supply the load on each relay. The difficulty to define the setting of relay operation setting that localize the fault would be increase. From these problems, it requires a method to reduce the complexity of coordination protection in ring distribution system with zone selective interlocking method which is modelled and adapted by using artificial neural network. In this paper, adaptive methods would be used to localize the short circuit which is faster than the manual method (conventional). The output of the system is locating the short circuit current and the operation system relay which is modelled by a status system. The status can produce a relay setting that capable in every configuration on the system.
