How does reactive power regulate the voltage in the power system?

WebReactive power (vars) is required to maintain the voltage to deliver active power (watts) through transmission lines. Motor loads and other loads require reactive power to convert the flow of electrons into useful work. WebDec 10, 2003 · Active power — Current in phase with voltage, which is the power that performs actual work. Reactive power — Current lagging voltage by 90 deg (in quadrature), which does not perform work. Apparent power — The vectorial sum of the two. These three components of power can be visualized by the power triangle illustrated in Fig. 1. WebJan 26, 2024 · Reactive power is the resultant power in watts of an AC circuit when the current waveform is out of phase with the waveform of the voltage, usually by 90 degrees if the load is purely reactive, and is the result of either capacitive or inductive loads.
