Facility Power Quality Management (442)
Problem: Need effective methods to limit transfer of poor power quality problems from facility equipment onto the grid.
Project Activity Scope (from Technical Overview Chart): Interaction Mechanisms through Integrated Systems.
PNNL Solution:
- Developed concept for a class of active "power quality-improving" (PQI) devices to reduce transfer of local equipment electrical noise back onto the grid
- Designed, fabricated, and tested a prototype PQI electronic controller
- Confirmed ability of PQI modules to significantly inhibit transfer of site noise onto the grid
Capabilities Employed to Meet Client Needs: Knowledge of harmonic power quality issues in electrical power distribution systems; knowledge of power factor correction needs in electrical power distribution systems; electronic controller design and development; low-voltage power electronic device design and development; identification of interruptible distributed equipment in large-scale use; simulation and prediction of aggregate benefits that can be achieved by inserting power quality correction devices within electrical distribution systems; field demonstration of load controllers; appliance standards development; laboratory-scale testing; measurement, evaluation, and documentation of performance.
