Reactive power flow equation
WebReactive power has limited effect on LV distribution networks and can often be ignored for initial assessment of the connection of small domestic PV systems. However, the flow of reactive power is the main factor determining the voltage on high voltage (≥10 kV) networks. The effect of PV generation supplying local loads reduces the flow of ... WebReactive power is a critical component of AC power systems, and it plays a crucial role in sustaining the magnetic and electric fields of inductors and capacitors. The reactive power formula is Q = V × I × sin (φ), where Q is the reactive power, V is the voltage, I is the current, and φ is the phase angle between the voltage and the current.
