Base station wind power source load calculation

Wind Load Calculation Wind load is calculated using the following equation: Fw = 1 2 C V ⋅ ⋅ dp ⋅ ⋅ ⋅A ( ) ρ λ 2 Where: • Fw = Force due to wind (lbf, N) 3 3 • ρ = Air Density (.075lb/ft , 1.22 kg/m ) • Cdp = Profile Drag Coefficient (from text or experimental data) • λ = Length/Width Aspect Ratio Correction Factor • V = Wind Velocity (ft/s, m/s) • 2 2 A = Cross Sectional Area Normal to wind direction (length*width) (ft ,m ) 3 Table 1.

Superconducting power storage

Superconducting energy storage systems utilize superconducting magnets to convert electrical energy into electromagnetic energy for storage once charged via the converter from the grid, magnetic fields form within each coil that is then utilized by superconductors as magnets and returned through power converters for use elsewhere when required – like back into grid power or loads via power converters that manage the exchange.
