KW vs kVA: Understanding the Difference Between Real and Apparent Power.

kW (kilowatt) and kVA (kilovolt-amps) are two measures of Công suất máy phát điện that are frequently confused. The difference matters because Máy phát điện are rated in kVA, but most loads are specified in kW. Mismatch leads to undersized or overpriced equipment.

The Simple Formula

kW = kVA × hệ số công suất

For a standard 0.8 Hệ số công suất máy phát điện: 1 kVA = 0.8 kW. MỘT 500 kVA generator delivers 400 kW công suất thực.

kVA Rating	kW at PF 0.8	kW at PF 0.9	kW at PF 1.0
100 kVA	80 kW	90 kW	100 kW
200 kVA	160 kW	180 kW	200 kW
500 kVA	400 kW	450 kW	500 kW
1000 kVA	800 kW	900 kW	1000 kW
2000 kVA	1600 kW	1800 kW	2000 kW

Why Power Factor Matters

hệ số công suất (PF) measures how efficiently electrical power is used. A PF of 1.0 means perfect efficiency; 0.8 means 20% is reactive power. Most industrial facilities operate between 0.8 Và 0.95 PF.

Low power factor loads (động cơ, máy biến áp, fluorescent lighting) require higher kVA ratings even though the kW draw is moderate. Always check your facility’s power factor before selecting a generator.

How to Convert Between kW and kVA

kVA to kW: Multiply by PF. Ví dụ: 100kVA × 0.8 = 80kW
kW to kVA: Divide by PF. Ví dụ: 80kW -> 0.8 = 100kVA
