n a major contract the Jubaili Brothers has supplied and installed 32 x 60 kVA diesel generators for a key industrial project in the UAE. The equipment which has been supplied features:
-1.92 MVA of prime power (1.92 MVA of prime power is equal to 192,000 watts (MW). This is calculated by multiplying the megavolt-amperes (MVA) by the conversion factor of 1,000,000 watts per kilovolt-amperes - 32 gensets, prime 60 kVA each (part of 6MVA industrial project).
All units have been customized and engineered for special industrial applications in a desert climate where reliability matters most.
- Each unit comes with a special light yellow custom canopy and company branding.
Altogether, 1.92 MVA of prime power is equivalent to approximately 183.6 kW when considering a power factor of 0.9.
In the UAE power plant capacity is generally rated in megawatts (MW) instead of megavolt-amperes (MVA) because MW represents the real power. It is the actual usable energy delivered to the grid or load, which is what truly matters for energy generation and consumption. MVA, on the other hand, represents the apparent power, which includes both real power (MW) and reactive power (measured in megavars, MVAR).
In a generating station, the prime mover (such as a turbine) produces only active power, measured in watts. The generator then converts this mechanical power into electrical power, calculated as Volts × Amps × Power Factor. This electrical power is then transmitted and distributed throughout the power system. Since the output depends solely on the mechanical power provided by the prime mover, the capacity of a power plant is rated in megawatts (MW), not MVA. In other words, regardless of how large the generator is, the actual power output is limited by the capacity of the turbines.
For example, if a 50 MW turbine is connected to a 90 MVA alternator (which is capable of supplying both active and reactive power), the plant will still only generate 50 MW of active power at full load. similarly, a 500 MW power plant delivers 500 MW of real power, but its MVA rating would depend on the power factor (e.g., at a power factor of 0.8, it would be 625 MVA).
