SCD: Signal Descriptions “desc” attribute of Data Objects should be present in SCD file IEC 61850 allows to hide 61850 Instead of Complex Addresses, use signal names from Engineering If unavailable, use smart names from StandardPage 13
Describing GOOSE connections 2 ways to define subscriptions in SCD: Subscribers in GOOSE Control Block of Publisher ExtRef in Subscribers Use of LGOS Logical Node for GOOSE Subscription One per Subscription Enable Monitoring of Receive Status Benefit Check of GOOSE links: Verify Publisher Verify mismatches by comparing traffic with SCD Verify Reception with Subscribers LGOSPage 14
Report Configuration Reports used for SCADA Communication One-to-one connections between IED and Clients Reports can be reserved “Owner” attribute Described in SCD Benefit Check Report links: Verify “Owner” is the Client defined in the SCDPage 15
Network Design Considerations Testing Requirements should be considered for Network Design Clear Access Points for Testing considering: Topology: Station Bus and Process Bus Traffic Control: VLAN and Multicast Filtering Redundancy: RedBoxPage 16
Example: Testing Interlocking Logics CILO LN shows interlocking logic resultfor each switchPage 17
Example: Troubleshooting Tracing Signals through the SASPage 18
Example: Re-testing after Security UpdatesPage 19
Conclusion SCL is a very powerful aspect of IEC 61850 Challenges: Some features are Optional Lack of Tools Requirements to be considered during System Design and Engineering Benefits go beyond engineering: Testing / Monitoring Cybersecurity Documentation Save Time and Increase Efficiency Using what SCL OffersPage 20

The new substation will sit on the footprint of the oldest structure and extend a little beyond. The second substation will be demolished. At completion of the project there will be only one substation. In answer to the survey posted on the internet concerning the project we have prepared a sheet answering those questions they are as follows:
