Measurement and compensation of fictitious power under nonsinusoidal voltage and current conditions

Abstract

The definitions of power are reviewed to establish a method for fictitious power measurement and to derive fictitious power compensation criteria in power systems with nonsinusoidal currents and voltages. A time-domain definition of power, using correlation techniques, is proposed. This leads to the proposal of a network parameter. A combination of digital and analog signal-processing techniques is proposed in the measurement and analysis of the components of power. The results of simulated and practical power measurements, the latter on an experimental electronic pulsewidth-modulated power converter, used for fictitious power compensation are given.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
