Comparison Analysis And Application On Feeder Automation Scheme Of Distribution Network

The power distribution automation is such an integral system that can achieve supervisory on-time, coordination and control. It can supply safe, economic, reliable and huge-quality power for consumer, Feeder automation is a main content of distribution automation. Its function includes such contents as deciding fault section, isolating fault and restoring healthy section supply.This paper takes a distribution network as an example, analyzing selection and verifying of line and switches. It pointed out that the selection of line should consider the load transferring and switches selection and placement should be linked with feeder automation practice and should provide foundation for its application.This paper selects loop-network unit and recloser to realize feeder automation considering city construction's need. This paper applies difference principle to analyze fault-treatment and isolation. At last, some preliminary discussions are made on communication and organization way.
