New York OGS
This project was a major in-service substation upgrade, with two 115kV feeders coming in, and four transformer banks totaling over 80MVA capacity. Each transformer bank fed a lineup of associated switchgear, with a total of 47 feeders supplying a variety of loads. The upgrade was performed in a complex series of steps, with minimal disruptions to loads by the fantastic project team consisting of O’Connell Electric and Reynolds Engineering.
Project Highlights
- Substation Automation & Integration
- Integration with over 150 IED’s!
- Substation HMI Development
- RTU Programming
- Building Management System Integration
- Testing & Commissioning
Client Challenges
This substation upgrade included a complete rebuild of the existing protective relaying, metering, and SCADA systems…in addition to substantial changes to the layout, number, and type of feeders. The existing substation’s SCADA and automation system consisted primarily of analog metering, solid-state or early-generation microprocessor-based protective relaying. Some integration with an upstream SCADA and BMS platform was in place, but minimal.
The multi-stage upgrade plan presented several logistical problems with the SCADA platform upgrade, including weighing complexity vs. value for cutover of various devices into the new platform. Integration and testing with over 150 local devices, both new and existing, would need to be performed. A notable portion of the existing P&C and SCADA equipment documentation was missing, further compounding the integration challenges.
Newtility’s system integration efforts needed to be carefully coordinated with the facility owner and project team in order to be successful.
Our Solution
If there ever was good evidence that a successful project is a team effort, this project was it! Working with the top-notch project team at O’Connell Electric and Reynolds Engineering, we were able to develop and implement a Substation Automation platform that met the project’s technical and logistical needs.
Newtility’s scope involved the following key aspects:
- System Architecture development
- Substation RTU programming
- Substation HMI development
- Data flow diagrams
- Cable block diagrams
- BMS integration via BACNET
- Transformer Load Tap Changer programming
- Multiple ATS controller settings and integration
- 125VDC battery condition monitoring system integration & setup
- Settings development and modification of a variety of relays, meters, IED’s and devices
- Testing & Commissioning
This was an unusual, interesting, and challenging project…but Newtility was up to the challenge and able to turn it into a solid success story with a happy customer!
