SCATTERED AND REACTIVE CURRENT, VOLTAGE, AND POWER IN CIRCUITS WITH NONSINUSOIDAL WAVE-FORMS AND THEIR COMPENSATION

This paper discusses properties of the current and power decomposition into the active, scattered, and reactive components. The relative character of this decomposition is analyzed along with orthogonal decomposition of the load voltage. It is shown that this relative character emphasizes the change of the power flow with the cross section observed. It emphasizes the difference in efficiency of the source apparent power compensation possible to achieve with a shunt and with a series compensator. It is also shown in the paper that not only the reactive power Q(r), but also the scattered power D(s) can be wholly compensated by a linear reactive compensator, so that the apparent power S of the load can be minimized to its active power P.
