For power systems, real-time monitoring is crucial. However, since the operation of the power system relies on a large number of existing equipment, real-time monitoring is extremely challenging for operation and maintenance personnel. Although most power systems have transformation and upgrading plans, they are often unable to implement them due to tight budgets. For substations with limited budget, the ideal solution is to connect the existing infrastructure to the IEC 61850 network, which can significantly reduce the investment required.
Existing power systems that have been in operation for decades have installed many devices based on proprietary communication protocols, and replacing all of them at once is not the most cost-effective option. If you want to upgrade the power automation system and use a modern Ethernet-based SCADA system to monitor field devices, how to achieve the lowest cost and the least human input is the key. Using interconnect solutions such as serial device servers, you can easily establish a transparent connection between your IEC 61850-based power SCADA system and your proprietary protocol-based field devices. The proprietary protocol data of field devices are packaged into Ethernet data packets, and the SCADA system can realize real-time monitoring of these field devices by unpacking.
Moxa's MGate 5119 Series substation-grade power gateways are easy to use and quickly establish smooth communication. This series of gateways not only helps realize fast communication between Modbus, DNP3, IEC 60870-5-101, IEC 60870-5-104 equipment and IEC 61850 communication network, but also supports NTP time synchronization function to ensure that data has a unified time stamp . MGate 5119 series also has a built-in SCL file generator, which is convenient for generating substation gateway SCL files, and you don't need to spend time and money to find other tools.
For real-time monitoring of field devices using proprietary protocols, Moxa's NPort S9000 series serial device servers can also be deployed to connect serial IEDs to Ethernet-based infrastructure to upgrade traditional substations. This series supports up to 16 serial ports and 4 Ethernet switching ports, which can pack proprietary protocol data into Ethernet packets, and easily connect field devices to SCADA systems. In addition, NPort S9000 series supports NTP, SNTP, IEEE 1588v2 PTP, and IRIG-B time synchronization functions, which can both self-synchronize and synchronize existing field devices.
As you strengthen your monitoring and control substation network, you must improve network device security. Moxa's serial device networking servers and protocol gateways are just the right helpers to deal with security issues, helping you solve various hidden dangers caused by field device networking. Both devices comply with IEC 62443 and NERC CIP standards, and have multiple built-in security functions to comprehensively protect communication devices through measures such as user authentication, setting the IP list allowed to access, device configuration and management based on HTTPS and TLS v1.2 protocol security from unauthorized access. Moxa's solution also regularly performs security vulnerability scans and takes necessary measures in a timely manner to improve the security of substation network equipment in the form of security patches.
In addition, Moxa's serial device servers and protocol gateways are compliant with IEC 61850-3 and IEEE 1613 standards, ensuring stable network operation without being affected by the harsh environment of substations.
