Design And Research Of Feeder Automation System In Xinhe County

In order to solve feeder automation system failure rate is relatively large,power outages frequently,power outage area is relatively large,isolation time is relatively long,can not real-time monitoring the switch equipment on the line.In this paper,a feeder automation system based on FTU and circuit breaker is proposed.Feeder automation is combined with field control and remote control,which greatly shortens the time of line fault processing,reduces the number of blackouts and the area of power failure.The power supply reliability of distribution system.In order to realize the automatic operation of feeding system,three kinds of protection modes,main line switch protection mode,branch line switch protection mode and contact switch protection mode are proposed in this paper.In actual use,according to the specifics of the switch equipment on the feeder line Location and the need to achieve the corresponding function of the protection mode selection,each protection model based on the actual situation to determine the relevant protection logic,in this paper,the protection logic is divided into voltage time type,current time and voltage current three types,to solve the complex line And the number of switching devices on the line with a relatively large number of line switch protection timing and timing problems,shortening the processing time of the line fault,reducing the number of switching devices on the line action.In this paper,the proposed feeder automation system design scheme applied to the actual feeder line,significantly improved the reliability of the practice area,greatly reducing the fault processing time.Through the feed lines and feeder lines with the real-time monitoring equipment for the distribution network planning and design and operation and maintenance work to provide a guarantee.
