Integration and Interoperability of Substation Communications
A major challenge in the development of power automation systems is coordinating between the vast array of standards and proprietary protocols for device and system communication. Various control devices, such as protection relays, controllers, switchgears, and RTUs, still use different legacy protocols. Automation systems need to integrate all of these devices, even though they may be using different protocols. IEC 61850 was developed as a standard substation communication protocol, defining all aspects of device communication for better extensibility and interoperability based on Ethernet technology
Scalable Network Infrastructure
Substation and transportation automation networks can be very large and cover expansive territories. Moxa's PowerTrans rackmount switches satisfy the scalable network requirements from Layer 2 to Layer 3 Ethernet switches.
The PT-7828 layer 3 Ethernet switch can divide a large-scale network into multiple subnets. Controlling network traffic on different subnets is a great technique for improving the performance of the network.
The PT-7728 and PT-7828 support full-fiber configuration with a maximum of 18+4G fiber ports to support long-haul, EMI immunity communications.
The PT-7324's smart functions simplify network management, such as setting up port-based VLAN and QoS.
Security is enhanced with built-in support for IEEE 802.1X, HTTPS, and SSH.
Redundancy for Higher Network Availability
PowerTrans rackmount switches provide multiple levels of redundant features:
Media redundancy
Each PowerTrans switch supports the Turbo Ring redundant topology with the world’s fastest recovery time at 20 ms. Standard STP and RSTP protocols are also supported for network redundancy. In addition to single ring structures, Turbo Ring supports multiple ring architectures with coupling functions such as “Ring coupling,” “Dual homing,” and “Dual Ring”.
Power input redundancy
With dual power inputs that support 24/48 DC and 119/220 AC/DC, PowerTrans switches can remain operational even if one power supply fails or is disconnected.
Configuration redundancy
The ABC-01 is an optional tool that can automatically save and restore the configuration of a PowerTrans switch. Use the ABC-01 to reduce downtime or to speed up mass configuration for large-scale networks.
Flexible Hardware Design Multiple media options
Since PowerTrans Ethernet switches have a modular design, users can put together a custom combination of Gigabit and Fast Ethernet ports with fiber or copper connections. 19 different modules are available, offering the following benefits:
Greater flexibility for system design and faster network change-up
Easier maintenance and lower cost of spare parts
Lower cost and less risk for future upgrades
Cable installation options
The PowerTrans series provides different options for cable connections. Front panel cabling is ideal for maintenance while rear panel cabling provides a neat and careful arrangement that is safer in case of port connection drops.
Rugged Design Withstands the Toughest Conditions
The rugged design of PowerTrans switches makes them well-suited for the critical communication requirements of power utility and transportation automation applications.
19-inch rack-mountable design for substation and traffic control rooms
-40 to +85°C wide operating temperature range for utility substations and industrial environments
