Introduction

Entergy’s dive into IEC 61850 began in a file

room deemed “lab”

The lab evolved into an open test bed for

multivendor interoperability

Pilot Substation - Joliet

230kV Substation containing two 100 MVA

Power Transformers

Pilot objective: Validate whether or not an IEC

61850 protection system is comparable with an

existing copper system

Digital system operating in parallel

Results

Reporting accurate data to control house HMIs

Lack of operations yielded minimum data

Entergy has begun conceptual design of its next

digital substation

Conclusion

Joliet is continuing to be monitored with plans

of installation of merging units to additional

 breakers in the works.

Entergy is currently procuring lab equipment to

 begin design, testing, and training for

deployment at Culicchia Substation.
