Determination of power-supply reliability with regard to power quality
Russian Electrical Engineering, 2014The reliability indices of the power supply of the load nodes are currently determined without taking power quality into account. At the same time, it is known that power systems with inferior power quality indices suffer from a significant increase of primary-equipment failures. Consequently, more load power is lost and its value increases.

The hidden cost [power supply quality]
Computing and Control Engineering, 2007Power quality, which encompasses a wide range of power supply parameters, has become a hidden issue for UK industry both in terms of security of supply, regulatory compliance and potential production downtime. Managing power quality can reduce costs, increase availability and improve security of supply. Uncorrected power quality (PQ) issues can bring a

A reconfigurable uninterruptible power supply system for multiple power quality applications
Twentieth Annual IEEE Applied Power Electronics Conference and Exposition, 2005. APEC 2005., 2005A novel topology of a modular per-phase uninterruptible power supply (UPS) system based on reduced-switch-count configuration is proposed in this paper. The proposed power conversion methodology offers active front-end filtering capability which ensures unity input power factor (reactive power compensation) and low input total harmonic distortion ...
