IED FOR, AND METHOD OF ENGINEERING, AN SA SYSTEM

摘要

The present invention proposes to equip IEDs for Substation Automation, such as bay units or substation PCs, with a Central Processing Unit CPU that includes a first processing core dedicated and configured to execute Protection and Control applications, and a second processing core, or network core, dedicated and configured to handle or decode network communication traffic. In a preferred embodiment, the network core performs computationally expensive pre- or post-processing functionality on top of the 9-2 communication stack. A plurality of network cores or a plurality of network interfaces may be needed to cope with the expected amount of IEC 61850 9-2 traffic.
