In AC electrical systems, phase-shifting between voltage and current introduces the concept of complex power, which has active power, reactive power, and apparent power as its components. Understanding complex power is fundamentally important for AC electrical system analysis, operation, a...
Some energy experts talk about reactive power as part of a capacitor’s movement that resembles the movement of a clock pendulum from its zenith to its nadir. In this analogy, as the pendulum swings up, the alternating current is supplying active power to a destination device. As the pendulum...
Reactive power is power that is reflected back to the grid - as opposed to active power, which is power that is consumed by the load.

What is reactive energy? Ask Question Asked 4 years, 3 months ago Modified 4 years, 3 months ago Viewed 5k times This question shows research effort; it is useful and clear 0 Save this question. Show activity on this post. We know the typical equation for instantaneous power (whi...
But if the voltage is pure sinusoidal, it has no higher harmonics and the current harmonics will not create reactive power (nor active power) in my view. It would be great if this was generally seen as 'distortion power' D that adds to P and Q in a quadratic w...
What is reactive power:Power factor is defined as the ratio of real power to apparent power. This definition is often mathematically represented as kW/kVA, where the numerator is the active (real) power and the denominator is the (active+ reactive) or apparent power. Though the definition ...
real power is provided given the load sees a voltage & current of the same frequency that has at least some components in phase. reactive power is that power, for example in a transmission line that is 'sloshing around' but not delivering any work to your load. uncompensated inductance is ...
6. Both the active power sent and the reactive power consumed by THE DC transmission can be controlled manually or automatically, which is more conducive to the economic operation and modern management of the power grid. Two, the disadvantages of high voltage DC power supply ...
IfParepresents the apparent power in a complex AC circuit,Ptrepresents the true power, andPrrepresents the reactive power, then the following equation holds: Pa2= Pt2+ Pr2 How does apparent power differ from active power? Apparent power is the total power that's available to run a computer,...
