This paper presents a new line-interactive UPS (uninterruptible power supply) system with active power-line conditioning capability. This system uses one power electronic inverter to implement two functions: maintaining uninterruptible power for critical loads, and suppressing power-line harmonics. The system offers efficient and economical power conditioning. Experimental validation is given.

Accurate power line channel models are an essential asset for the development of advanced power line communication systems. A physically based power line communication channel model is derived. Elements within a power line network, e.g. line discontinuities, branches, and loads, are modelled as IIR-filters. The transfer function of the overall channel is calculated by concatenating the transfer...

In this paper, a home network message specification for white goods based on power line communication is proposed. It is designed for white goods such as air conditioners, refrigerators, washing machines, etc. The proposed home network message specification is composed of a virtual device service and a devicespecific attribute. For practical implementation, an application software and two types...

The power system has been used for communication purposes for many decades, although it was mainly the power utility companies that used low bit rates for control and monitoring purposes. In the last ten years, however, the deregulation of the power and telecommunication markets has spurred the idea of using and commercializing the power networks for a range of new communication applications an...

The issue of how to measure magnetic induction fields generated by various power line configurations, when there are several power lines that run across the same exposure area, has become a matter of interest and study within the Regional Environment Protection Agency of Friuli Venezia Giulia (ARPA FVG). In classifying the various power line typologies the definition of double circuit line was ...

in this paper we show that if q is a power of a prime p , then the projective special linear group psl(2, q) and the stabilizer of a point of the projective line have maximum sum element orders among all proper subgroups of projective general linear group pgl(2, q) for q odd and even respectively

This study inspects the optimum location of STATCOM device in long transmission line to acquire the maximum power system transient stability improvement. STATCOM is a kind of prominent and effective shunt FACTS device which is used in power system to enhance the power system stability and to regulate the line voltage. When it has been placed at the center point of a transmission line, play a ke...
