The high-voltage distribution system is connected in a tree branch configuration so as to meet the need for high reliability feeding. When a service interruption accident occurs, the faulty section is automatically separated and the healthy section carries out power flexibility from an adjacent system, thereby reducing the service interruption area. The faulty section in the distribution system is quickly located by means of time relays installed in some switchgears in the distribution system. However, the setting points of these time relay must be constantly monitored.
As such, we have proposed a “section management method” which can supervise each section unit of the distribution system. Based on this method, we then developed a prototype automatic distribution system for the overall management of time relays using internal software, facilities and customers feedback.
This paper describes operation of the distribution system in regard to the “section management method” was used as.
