How to Use the Calculator
Input Generator kVA
- Enter the apparent power (kVA) rating of your generator.
- This value is usually found on the generator's nameplate.
- It represents the total power the generator can supply.
Input Power Factor (PF)
- Enter the power factor (PF) of the load connected to the generator.
- PF ranges from 0 to 1. For resistive loads, PF is 1.
- A typical PF for mixed loads is 0.8.
Input Efficiency (%)
- Enter the efficiency of the generator in percentage.
- This accounts for losses within the generator itself.
- Common efficiency values range from 85% to 95%.
Generator Power Fundamentals
Real Power (kW)
Kilowatts (kW) represent the actual power consumed by a load or supplied by a generator that performs useful work.
- It's the "working" power.
- Measured in kilowatts.
Apparent Power (kVA)
- Kilovolt-amperes (kVA) is the total power in an AC circuit, including both real and reactive power.
- It's the generator's total capacity.
Key Formula:
kW = kVA × Power Factor × (Efficiency / 100)
Calculation Formulas
Generator Kilowatts (kW):
kW = kVA × PF × (Efficiency / 100)
Watts (W):
W = kW × 1000
Megawatts (MW):
MW = kW / 1000
Example Calculation
Generator with:
kVA: 100 kVA
Power Factor (PF): 0.8
Efficiency: 90%
kW = 100 kVA × 0.8 × (90 / 100) = 72 kW
Watts = 72 kW × 1000 = 72000 W
MW = 72 kW / 1000 = 0.072 MW
