Highly Reliable, Low Cost Next Generation Network System For Digital Substation

摘要

The present invention relates to a high-reliability and low-cost next-generation network system for configuring a digital substation network, wherein the digital substation system includes an SA (substation-automation) operating device, an information linkage device, a time synchronization device, a network monitoring and diagnosis device, and a plurality of intelligent electric devices (IEDs). device) and a plurality of Ethernet switches, wherein the SA operation device, the information linkage device, the time synchronization device, and the network monitoring and diagnosis device transmit and receive data based on a parallel redundancy protocol (PRP) scheme, and the A plurality of IEDs can transmit and receive data based on the high-availability seamless redundancy (HSR) method, and the substation protection function can be optimized and operated even in the event of a network failure by the network monitoring and diagnosis device.
