Baud Rate – A measure of how fast serial data is moving between devices per second. 2 common levels are 19, 200 BPS and 9,600 BPS and now 115,200 BPS
Slew Rate – Speed we can go from -25 V to 25 V, limits baud rate DTE Data Terminal Equipment DCE Data Communication Equipment
conductors are electrically floating
2008 Proposed ANSI C37-2 Revision presented at Georgia Tech Relay Conference
Relays do not use DHCP - Dynamic Host Configuration Protocol
Max distance 100 meters or 328 feet
Cat 5 Cable
Cat 5e Cable
Cat 6 Cable (up to 250 Mhz)
Cat 6A (Augmented-up to 500 Mhz)
Traditional Breaker Wiring
Traditional Cable Trench
Thousands of Copper Wires from Switchyard
Labor Intensive Copper Wiring on Relay Panels
40 less cabling with no terminations required
1,000’s of wires replaced with few communication cables
Eliminates 33 of breaker terminations
Eliminate 90 of control building terminations
DNS - Domain Name System, Internet system to translate names into IP addresses
IP v4 and IP v6 (8 groups of 4 hex digits 0db8:2001:85a3:0000:0000:8a2a:0370:7334)
has become a designator for thenext generation substationsecondary systemwith a higher degree of integration, reduced cost, greater flexibility, communication networks replacing hard-wired connections, plug-and-play functionality, reduced construction and commissioning time, and other advantagesIEC 61850
There are Universal Gateways and controllers that collects metering, status, event, and fault report data from serial or LAN based Intelligent substation devices. The Gateways summarizes data from the substation devices and makes it available locally/remotely through a standard secure web browser (HTTPS).
