Sustainable building for the quality of power supply

2005 IEEE Russia Power Tech, 2005
The photovoltaic (PV) systems, together with energy storage devices, interconnected in parallel with the utility can improve the reliability during power quality perturbations in the main system supply. The paper presents a possible solution with high level of power supply continuity, where a hybrid system is simulated in case of power quality negative

Tools for supplying premium quality power

IEEE Technical Applications Conference and Workshops. Northcon/95. Conference Record, 2002
The electric utility industry has done a good job of minimizing the long term outage, but for some industries, reliable power is not good enough. There is an increasing demand for premium quality power. The proliferation of sensitive electronic equipment at industrial and commercial sites has resulted in an increasing number of major power users who ...

Power and relationship quality in supply chains

Asia Pacific Journal of Marketing and Logistics, 2017
PurposeThe purpose of this paper is to test the impact of power (coercive and non-coercive) on supply chain (SC) relationship success. In particular, this paper aims to examine the moderating effect of relationship quality (RQ) on the associations between power bases and relationship success.

Power quality monitoring at the supply side

2001 IEEE/PES Transmission and Distribution Conference and Exposition. Developing New Perspectives (Cat. No.01CH37294), 2002
/sup T/his paper summarizes a power quality (PQ) monitoring investigation conducted at the utility distribution substation level. The main goal was to determine the real-time PQ monitoring issues from the user's perspective: what type of data needs to be captured; and how it should be presented to the user.

Determination of power-supply reliability with regard to power quality

Russian Electrical Engineering, 2014
The 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.

Modular power conditioner concept for improving quality of supply

IECON 2015 - 41st Annual Conference of the IEEE Industrial Electronics Society, 2015
The mitigation of power quality issues by means of customized power conditioning systems are of growing interest in recent years. The electricity supply is exposed to more frequent power quality problems, especially due to the steadily increasing integration of decentralized power generation, penetration of renewable energy, and deployment of non ...

The hidden cost [power supply quality]

Computing and Control Engineering, 2007
Power 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., 2005
A 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 ...
