IEC 61850-based Substation Automation System
The IEC 61850 standard, which
has world-wide acceptance from a variety of utilities and
manufacturers, offers interoperability, overall cost savings,
and a simple architecture. However, actually realizing these
benefits requires a good Substation Automation System (SAS)
design.
For ultimate reliability and interoperability in substation communications, Moxa has introduced IEC 61850-3 and IEEE 1613 compliant Ethernet switches, industrial embedded computers as IEC 61850 protocol conversion gateways, and secure terminal servers for connecting legacy devices.
Discover Moxa’s Business Benefits
 Zero Packet Loss under Harsh EMI Stress
When high voltage circuit breakers
open or close they generate extremely strong electromagnetic
fields in their vicinity, resulting in high voltages and very
large currents that can adversely affect the operation of
critical Ethernet networks. Moxa’s PowerTrans Ethernet switches
are designed to work reliably under a variety of EMI phenomena
commonly found in substations, without experiencing a loss
in communications.
IEEE 1588 Version 2 Time Synchronization
Moxa’s PT-7728-PTP IEC 61850-3
fast Ethernet switches support the latest version of IEEE
1588 v2 technology to fulfill precise time synchronization
requirements for protection systems and control applications.
These Ethernet switches guarantee time-stamping accuracy within
1 μs for the IEC 61850 process layer. They can be configured
for 1558 v2 Master, Boundary Clock, and Transparent Clock
functionality .
Adding Intelligent Codes Creates Exceptionally Efficient and
Reliable Networks
Two heads are better than one,
and adding locally intelligent nodes can create networks of
exceptional efficiency and reliability. Without Moxa’s solutions,
substation control centers often have four different parallel
systems—the protection management server, SCADA host, five-point
prevention system, and a data logger server. By using Moxa’s
DA-710 x86-based embedded computer, all of the systems are
integrated into a single central management system. The embedded
computer also functions as a substation back-end host to ensure
availability for personnel at the remote dispatch control
center.
Non-stop Operation and Enhanced Determinism for Data Transmission
A substation Ethernet LAN is
an integral part of mission-critical protection and control
systems. These systems must perform extremely reliably to
create a reliable and non-stop communications network, as
well as to optimize and prioritize data communications between
systems.
