Gas plant alternate-feed study

Client
Rural electric association, WA
Role
Study engineer
Scope
6-feeder substation
Status
Delivered

A rural electric association serves a large gas processing plant and needed to evaluate an alternate feed from its six-feeder substation. Our team performed the distribution study end to end, and validated the models before trusting them.

Study one-line: existing and alternate feeds to the plant.

MODEL VALIDATION FIRST

The association’s GIS was compared against its WindMil engineering model. Conductor data, load allocation, and equipment records were spot-checked and corrections documented before any analysis ran.

POWER FLOW, FAULTS, COORDINATION

Existing and alternate configurations were analyzed for the plant load, fault duties were run from the transmission provider’s source models, and time-current coordination was developed for the affected feeders.

BOTTOM LINE

  • A client needed a yes-or-no on an alternate feed for their biggest customer.
  • Our team checked the data, ran the study, and delivered settings they could load.
