Power Distribution Feeder Automation - Application Story 2012
0 likes404 views
Feeder automation systems in Taiwan monitor and control power distribution networks. Korenix's fiber Ethernet switches and redundant ring technology were used to implement the fiber network connecting feeder terminal units along the distribution system. This enabled failure detection, identification, recovery, and reporting to minimize error handling time and ensure continuous network service when failures occurred on the fiber links.

- 2. Successful story www.korenix.com1 Application Story Feeder automation, a part of power distribution, has the function of monitoring, control, SCADA and FDIR on the distribution network. The system includes feeder dispatch and control center (FDCC), feeder remote terminal unit (FRTU) and feeder terminal units (FTU). Renewing power distribution system in Taiwan is the main task of its smart grid network development. Since 2009 TPC (TaiPower Company), the national electricity company of Taiwan, has started to upgrade feeder automation systems with up-to-date information and communication technologies. More than 8,500 pcs of FTU have been upgraded in the past few years. While the distribution network covers a wide range of areas, it is subjected to heavy weather and environmental conditions which may result in inevitable failures. TPC chose HCE as its FTU vender and system integrator to build a reliable and high quality distribution network. Korenix’ feeder automation network solution was adapted to implement the fiber network along the distribution system. Each JetNet 4508f, Korenix’ industrial 6+2 fiber Ethernet switch, in the FTU transmitted the data to the SCADA system. By enabling Korenix redundant ring technology, the MSR, any failure on the fiber links can be easily detected, identified, and recovered (FDIR). The failure location is also reported to administrators through Korenix visualized network management system, the JetView pro, which, as a result, minimizes the error handling time.

Failure Recovery/Restoration A link failure is recovered within 5 ms to ensure the continuous network service. During link restoration, Korenix Seamless Restoration guarantees a 0 ms process without any side effect to the network. Solution JetView pro Network Management System Failure Detection The solution continuously monitors the health of the network. Warning events are reported to field engineers and central officers by system LED, email, SNMP trap, or the visualized network management system, the JetView Pro.

This prolongs FTU’s life time especially when the FTU operates on its internal UPS/battery. Hardened for Extreme The heat-generating components are attached to the entire aluminum body. This outstanding cooling effect helps JetNet 4508f work at -40~75oC with IP31 protection. Slim, Space Saving Just as wide as a business card saves the space of the FTU box.
