Station 38 Protection and Integration

Monroe County, NY

ECI staff delivered relay settings and automation for a phased refurbishment of Station 38 (ST-38), which is a major distribution station in the heart of Rochester, NY. ST-38 is an indoor substation with multiple interior levels.  The construction sequence called for adding new floors to the open gallery of the building, installation of GIS switchgear, Testing & Commissioning of new equipment and finally demolition of existing equipment after the new equipment was in-service.  This resulted in a seven-phase project with significant coordination and commissioning challenges. 

Our engineering team was responsible for developing all relay settings; the station had approximately (100) new Protection & Automation IEDs. We also developed the System Automation Platform using CIMPLICITY for the Station HMI , (3) SEL-3350 RTACs for the RTU and (25) network switches.

Our commissioning team managed and performed all onsite SP&C 3-7 commissioning efforts including configuration of all relays and automation equipment, performing secondary injections, relay logic and protection testing, HMI and SCADA checkout, functional testing of all protection schemes and finally performing primary injection testing using Avangrid’s diesel generator short circuit test and/or a primary injection test set. 

This project required seven phases of work to complete as the new equipment needed to be installed and commissioned at an indoor substation which remain in service until replacement equipment was ready. Our team was responsible for preparing energization sequence plans, drafting switching orders for outages with the Energy Control Center, and coordinating all testing and energization activities onsite.

* Note: for this project our team oversaw P&C Technicians provided by a subcontractor.
