6. Consider renewable energy (hydro, solar, and wind: circle closest answer) a. A hydropower plant at Niagara Falls has a capacity of 2675 MW at a head of 51 m and is 90% efficient. Flow rate in m³/s: 1200 6700 9800 10500 12000 b. Consider a 25% efficient solar array with a daily insolation of 5 kWh/m². To supply 1500 kWh monthly, the array area in m²: 20 30 40 50 60 c. A 5 MW 35% efficient 3-blade HAWT has a rated wind speed of 12 m/s. Blade length in m: 26 42 50 68 84 7". A balanced 3-phase 3-wire 12.47 kV 60 Hz System serves a 2500 kVA delta-connected 3-phase load, pf = 0.28 lagging. (a) Complete the load power triangle. (b) Determine the ratings (V, Q) for each of three delta- connected capacitors to be installed to correct the source pf to 0.8682 lagging. (a) (b) kvar OF7 어 100 1 kV
