Megawatts equal how many kva?

Answer 1

A kVA is 1000 watts. Where k stands for kilo or 1000. V for volts A for amperes. A watt is a volt X a ampere. Mega means 1 000 000 so a megawatt= 1000 kVA.

Note: This is only true for resistive loads like heaters and lightbulbs.

Answer

You cannot really ask 'How many watts equal how many volt amperes?', because you are describing two different quantities, as explained below:

Alternating-current loads are often combinations of resistance and reactance (reactance is the opposition to current due to either inductance, or capacitance, or a combination of both).

Loads having both resistance and reactance exhibit true power and reactive power.

True power describes the rate at which energy is permanently lost due to the resulting temperature difference between the conductor(s) and the surroundings. True power is associated with purely resistive loads, and is expressed in watts.

Reactive power describes the rate at which energy is alternately stored in a magnetic or electric field then returned to the supply. Reactive power is associated with purely reactive loads, and is expressed in reactive volt amperes.

Apparent power is the vector sum of true power and reactive power, and is expressed in volt amperes.

The relationship between true power and apparent power is:

true power = apparent power x power factor

Power factor varies from zero (purely reactive circuit) to unity (purely resistive circuit). So, true power (in watts) will only equal apparent power (in volt amperes) when the power factor is unity -i.e. in a purely resistive circuit. For all other types of circuit, the true power will always be less than the apparent power.

Answer 2

Megawatts (MW) and kilovolt-amperes (kVA) are not directly convertible because they measure different things. Megawatts represent real power, while kilovolt-amperes represent apparent power. The relationship between them depends on the power factor of the system. To convert MW to kVA, you would need the power factor of the system.

Answer 3

100,000KVA - depending on the power factor of the circuit under load. Watts (W) is a measure of work performed, while KVA is the simple product of the current draw and the voltage potential at the source.
