We worked closely with UGIES Operations, Engineering, and associated vendors to determine the feasibility and required electrical system modifications for the proposed 5000 HP motor swap. As part of this effort, we reviewed the existing conditions against the provided documentation and validated the adequacy of the existing substation transformer.
The review started at the main power feed into the facility and concluded at the existing 4000 hp motor. As the information was gathered, we followed up with the VFD manufacturer to determine whether the internal workings of the VFD could handle the upgraded 5000 hp motor. Based on the information collected, all necessary modifications were documented and presented to the owner, which included, but was not limited to, the following:
- Incorporation of Field As-Built Redlines
- VFD Component Confirmation
- Feeder Resizing Calculation
- Revised Settings for The Motor Breaker
- Main Breaker Protective Relays Settings
As for the 16-inch recycle valve, we collected and reviewed the owner’s vendor data as well as on-site conditions. It was determined that the existing infrastructure was sufficient to power and control the recycle valve, which reduced project cost.
During the design phase of this project, the owner reviewed and approved our recommendations, and an “Issue for Construction” package was assembled, detailing all necessary electrical infrastructure modifications.
