Inverter instantaneous power

4 FAQs about [Inverter instantaneous power]

What is a control strategy based on instantaneous power theory?

The control strategy, based on instantaneous power theory, can directly calculate the active and reactive component of currents using measured grid voltage and currents and generate inverter switching pulses based on the formulated reference current values and thus helping to improve the dynamic response when voltage sag takes place.

Why is instantaneous power q corresponding to powerless currents?

The instantaneous power q corresponding to powerless currents is due to the redistribution of instantaneous power between the conductors of the three-phase system by means of an active filter, since the total instantaneous power remains unchanged.

What is the modulus of instantaneous imaginary power?

Using the instantaneous nonactive currents iqj, the modulus of instantaneous imaginary power is defined as: Although in Willems' theory the currents ipj (j = a, b, c) are called the instantaneous active currents, these currents are known as power currents and they provide the same instantaneous power p as the original currents ij (j = a, b, c).
