BEEAM: Building Electrical Efficiency Analysis Model

Oct 14, 2020, 18:00 PM
BEEAM simulates the efficiency of building electrical distribution systems using harmonic power flow. BEEAM can model a variety of building distribution topologies, including three-phase AC, single-phase AC, unipolar DC, bipolar DC, and hybrid networks under balanced and unbalanced load conditions. BEEAM accurately models power electronic converter losses, provides granular estimates of losses throughout the distribution system, and properly models efficiency at part-load conditions.
