OverviewDistribution network communicates every branch distribution station, distribution terminal with every master station by using industrial grade Ethernet switches, to collect information, monitor, and remote control. Distribution network automation is comprises of two subsystems, distribution network SCADA system and remote meter reading system, these two systems require different for data security, transmission delay, transmission reliability. Distribution Network SCADA SystemDescriptionDistribution network SCADA system is used to collect data from transformer substation, switching station, distribution substation, and RTU,TTU,FTU in the looped network cabinet, and also used to remote signaling, telemetry, remote control, condition monitoring ,alarm, sequence of event order.

DescriptionEPON combined Ethernet technology with PON technology, which is not only has Ethernet service, but also can prevent electromagnetic interference, thunder attack, and networking flexible. So that it is commonly used for city power distribution. EPON networking connects distribution main station system with every terminal substation system by PON, to upload and download information, putting OLT beside transformer substation, by using POS splitter and ONU to distribute and collect data. PON is pure medium network, which is good at anti-electromagnetic interference, and anti thunder attack, it also has broadband for fiber transmission, Good communication capacity, low transmission loss.RequirementsOutdoor installation, designed to stand up to the harsh environmental and extreme temp...
