Q1) Generator Produce 25 KW to charge battery and the load is 2.2 KW
1- Calculate the Capacity of the battery ? Please write the Calculation Equation
2- Calculate the specific power of the battery? Please write the Calculation Equation
Homework Answers
1)
Generator Voltage : 120 V ( in AC single phase )
Power = 25 kW = V*I
So , I = 25kW / 120 V = 208.33 A
So battery capacity
=Current * time in hours = I * 1 hour = 208.33 Ah
capacity = 208.33 Ah
2)
Specific Power = Energy in kWh / weight
Let weight of battery 4 kg (For lead Acid batteries )
So , Specific Power
= 25kWh/ 4 kg
= 6.25 kWh / kg

Two three-phase generators supply a three-phase load through separate three-phase lines. The load absorbs 30 kW at 0.8 power factor lagging. The line impedance is (1.4 +J1.6) Ω per phase between generator G1 and the load, and (0.8 +jl ) Ω per phase between generator G2 and the load. If generator Gl supplies 15 kW at 0.8 power factor lagging, with a terminal voltage of 460 V line- to-line, determine 1. The voltage at the load terminals. 2. The voltage...

If a 25-kW (rated) wind turbine has a three-phase, 480-V generator, what minimum size wire will be needed for each phase to connect the wind turbine to a load that is 50 m away? Remember, you need to count the length of wire down the 25-m tower. Peak power can be 30 kW. Calculate maximum current and reduce it by a factor of 1.7 because the system is three-phase. Each leg (wire) of the three-phase system carries 1/3 of the...
