Current IEC 61850 standards includes PRP/HSR (parallel redundancy protocol/high-availability seamless redundancy) protocol. PRP/HSR specifies how to use two Ethernet networks to ensure seamless failover if one of the redundant networks fails.
This client has a 345 kV generation substation located in Korea. The client wanted to upgrade and implement ESS (Energy Storage System) to enable remote monitoring of the state of the energy stored.
By design, the IEC 61850 standard places great emphasis on reliability. Not only are many of the devices required to be rugged enough to withstand extreme environmental conditions, the network itself has to be redundant on many different levels.
One of the major advantages of implementing an Ethernet network is that it is easy to expand when the need arises. In addition, any new products that connect to an existing IEC 61850 substation are required to be fully compatible with what’s already there.
Moxa's PT-G503 shortlisted for this project as it is easy to configure. PT-G503 also offers one dedicated Ethernet port for monitoring and troubleshooting. PT-G503 Series also provides IEEE 1588v2 PTP in end-to-end one-step transparent clock mode for timing-critical applications and isolated redundant power inputs with 24/48 VDC or 110/220 VDC/VAC power supply ranges to increase the reliability of the power supply.
