Test Report: Raytheon/KTech RK30 Energy Storage System.

摘要

The Department of Energy Office of Electricity (DOE/OE), Sandia National Laboratories (SNL) and the Base Camp Integration Lab (BCIL) partnered together to incorporate an energy storage system into a microgrid configured Forward Operating Base to reduce the fossil fuel consumption and to ultimately save lives. Energy storage vendors will be sending their systems to SNL Energy Storage Test Pad (ESTP) for functional testing and then to the BCIL for performance evaluation. The technologies that will be tested are electro-chemical energy storage systems comprising of lead acid, lithium-ion or zinc-bromide. Raytheon/KTech has developed an energy storage system that utilizes zinc-bromide flow batteries to save fuel on a military microgrid. This report contains the testing results and some limited analysis of performance of the Raytheon/KTech Zinc-Bromide Energy Storage System. The Raytheon/KTech RK30 Energy Storage System uses twelve RedFlow Zinc-Bromide Battery Modules (ZBMs) and six single phase inverters to sink, store, and supply electrical energy. Each ZBM is rated to hold up to 10kWh and each inverter is rated at 5kW making the system rated at 30kW and 120kWh. The inverters are 208VAC phase to phase inverters and are connected to a delta to wye isolation transformer to allow an electrical wye system interface.
