The Pairing
A gigawatt-class data center campus served by an on-site fleet of industrial and aeroderivative gas turbines, distributed across multiple load feeders at medium voltage.
What Was at Stake
The offtaker needed to know what happens to the racks when a bolted three-phase fault lands on the load side. Not in principle — in milliseconds, with real machine dynamics, on the actual feeder configuration. Without that answer, no one could sign.
What We Did
Eradeh built a full electromagnetic transient model of the generation, the step-up transformers, the feeders, and the load, then ran the fault at the worst credible location and duration. We measured generator currents at the machine terminals, voltage and current at transmission voltage, and the voltage seen at every load feeder on the campus — capturing exactly how the plant behaves, feeder by feeder, from fault inception through clearing and load response.
The Outcome
A defensible, measured picture of ride-through behavior that both sides of the transaction could rely on — and a clear line of sight to the machine parameters that needed vendor confirmation before final design.
