Two 2000kVA Transformers for ARIES.1666 Variable Speed Hydro Generator - Site Infrastructure

7/02/2024

BACKGROUND

This procurement provides site-infrastructure equipment to integrate the Hydro Generator Emulation Platform (ARIES.1140) at the Grid Integration Research Pad (GIRP) area at Flatirons Campus.

The Hydro Generator Emulation Platform is two platforms currently being built off-site by a vendor. One platform will contain the power electronic controls including two Variable Frequency Drives (VFDs). The second platform will house two 1.25 MW motors to emulate a hydro turbine (motive force) and the other motor will emulate the driven electric generator.

This will be a regenerative configuration to provide electricity back to the Campus’ 13.2 kV electrical bus. The dyno motors will function individually or in tandem and will offer a mechanical coupling for an up to 2.5MW hydro-generator, as Device-Under-Evaluation.

These capabilities will allow demonstrations of hydro dynamics tied to the electric grid at MW-scale.

OBJECTIVE

National Renewal Energy Laboratory (NREL) is seeking to purchase two 2000kVA transformer to sufficiently power the VFDs on the emulation platform.

These transformers will provide the necessary electrical infrastructure to support the Hydro Generator Emulation Platform by utilizing existing electrical bus feeds at the GIRPs.
