摘要

The paper investigates the impact of various higher-order voltage harmonic components’ magnitudes and their diverse phase angles on the variations of reactive power. Four appliances (2 monitors, a CFL fluorescent lamp, and a LED tube system) were connected to a laboratory power supply featuring a fundamental harmonic component and simultaneous higher-order harmonic components. The measurement examines the influence of the consumption of each appliance. Three key parameters were prioritized for monitoring, including reactive power, active power, and total harmonic distortion of current.
