Product Details

IEC61850 Intelligent Substation Solution

A digital/intelligent substation is a modern substation built on the basis of the IEC 61850 communication protocol, consisting of intelligent primary equipment and networked secondary equipment. It enables information sharing and interoperability among intelligent electrical devices within the substation. A reliable and intelligent communication network is a key factor for the success of substations in transmitting and distributing electricity to large areas. Due to the special environment of the substation and the requirements of the automation system, the communication network within the substation automation system must have fast real-time response capability, extremely high reliability, excellent electromagnetic compatibility performance, and high security.

Topology Map

system requirements

·The internal process layer of IEC61850 substation uses SV sampling value message instead of the original hard wiring. The SV flow rate can reach several hundred megabytes and synchronous sampling is required
·From the occurrence of the fault to the action of the intelligent terminal, it is required to be completed within 4ms
·Require the network system to have long-term zero packet loss characteristics
·The synchronous sampling method requires the network system to provide accurate clock synchronization
·Specific EMC and temperature characteristics in the power industry
