Power Quality & Electrical Energy Use: Thank you Dr. Manuel Pérez Donsión

Power Quality

This book arises from different research projects on Power Quality Master classes on use and Electric Energy Quality taught at the University of Vigo. It isn´t only intended especially for electrical engineering students, but also teachers, technicians, public administrations, engineering enterprises, electricity consumers and all those who are willing to venture into this interesting and complex field of power quality and electrical energy systems. A lot of tabs, charts, figs & pics will make its reading easier.


In Chapter 1, the concept of quality of electric power is introduced and the three parameters to be analyzed: continuity of supply, quality of care and wave and relationship with the user. In Chapter 2 the rules on the quality of the energy question; Frequency variations are discussed in Chapter 3. Chapter 4 refers to the slow voltage variations and voltage fluctuations are studied in Chapter 5, their types and some of its consequences, such as flicker studied. In Chapter 6, voltage sags, surges and short interruptions are explained. In Chapter 7 voltage transients, surges, lightning, earthing and grounding techs are here analyzed. Chapter 8 discusses FACTS and HVDC equipment; Chapter 9 harmonics they are studied and, finally, in Chapter 10, voltage imbalances are treated.

It is a very complete and thorough treatment of the subject book and has a lot of tables, charts, figures and photographs; also it includes 30 pages with color photos and graphics to facilitate understanding of matter and makes it easier to read. Thank you Dr. Donsión

Karl Böer Solar Energy Medal of Merit International Award for Antonio Luque

Professor Antonio Luque, founder and president of the Solar Energy Institute has been awarded with the "Karl Böer Solar Energy Medal of Merit" award, given by the University of Delaware (USA), for his contributions to the development of photovoltaics. worth $60,000, the prestigious award recognizes the most outstanding international careers in the field of solar energy.

Thanks Professor Luque

Karl Böer prizes are awarded every two years in honor of the scientist, who was a member for years at the University of Delaware, founder of the Institute of Energy Conversion EE (UD's Institute of Energy Conversion) and one of the great researchers in solar cells. The jury awarded prizes consists of a committee which includes representatives of major US solar companies and government Department of Energy.

"Professor Luque has made outstanding contributions in the field of solar energy," said Michael Klein, Executive Director of Karl Böer Solar Energy Medal of Merit, announcing the winner in this edition. "In giving this award, we recognize the impact their work has had on the scientific and technological development of renewable energies. The selection committee is proud to make this announcement. "

A successful career

Karl Böer Solar Energy Medal of Merit recognizes the many achievements of Antonio Luque, who has several decades researching and improving solar PV technology, and turning these achievements into practical applications. In fact, Luque is one of the researchers who owes its solar energy development.

For years working in intermediate band cells, of which he has always said he is a real sun revolution. In 1969, Professor founded the Semiconductor Laboratory of the Polytechnic University of Madrid (UPM) and ten years later became the laboratory at the Institute of Solar Energy (IES), a highly recognized worldwide in photovoltaic research center.

Antonio Luque developed in 1976 Si - bifacial solar cells, which are active on both sides and are able to collect as much direct light as part of it is reflected on the front face, resulting in cells with very high efficiency. In order to manufacture these solar cells, Professor founded the company Isofotón in Málaga and became its first president until 1990.

CPV : Antonio Luque, Viacheslav Andrew

In its appreciation to the Spanish scientist, US jury award also highlights that Luque supported the adoption of a generous Feed In Tarifs System for the Spanish photovoltaic, which led in 2008 to 2.6 Gw commisioned to the Spanish Electrical network by producing more electricity with this technology than the medium nuclear power plant production (500 Mw).

Many awards

This is not, of course, the first award for Antonio Luque. Professor has many other national and international awards: the SolarWorld Senior Einstein Award SolarWorld (2008); the IEEE's William Cherry Award for Photovoltaic Science and Technology (2006); the Juan de la Cierva to Technology Transfer (2003) National Award; King James I to Research in the Environment (1999); the Edmond Becquerel Prize for Outstanding Contributions to the Development of Photovoltaic Solar Energy (1992); and the National Technological Research Prize Leonardo Torres Quevedo (1987).

Among the winners in previous editions of Karl Böer Solar Energy Medal of Merit include, among others, the German Hermann Scheer (2009), for his long contribution and commitment to the diffusion of solar energy, and Adolf Goetzberger (1997), founder of Fraunhofer Institute for Solar Energy Systems; David Carlson (1995), inventor of thin film solar cells; and US President Jimmy Carter (1993), who encouraged the development of this technology and aroused worldwide interest in photovoltaics.

Dear Quality Manager and Quality Production Team Leader:

Delivering Quality and Responsive Service is Vital While dealing with Durable Goods Inside Industrial Environments.

As my resume indicates, I have worked in Customer Services for more than fifteen years, I’ve been dealing and working with Calypso over my last three years with a little 2­µm. Uncertainty handling several Carl Zeiss 3D-CMM such us Eclipse 550, PMC-VAST-XT and Prismo-VAST; CNC-programming, measuring Customer Work-Pieces and reporting All measurements Inside the Blue-Prints were my common tasks as Metrologist so you won’t have to incur into great expenses while training me.

I would be very grateful if you could pease let me show you my Interest in the “Metrologist” position that was recently posted Inside “Experteer.de” as I think I would be a perfect fit for this position. Between my achieved goals I’ve deployed the 1st <1µ SACC-PRISMO CMM In Spain under Herr Hofman & Mr. López Mora SuperVision Inside BOSCH Quality-Room at BOSCH Aranjuez Factory, later on In the actually non-existent Alcalá de Henares’es BOSCH factory where I personally instructed a little application training to four metrology professionals including Measure-Fit and Measure-Mind software packages over an OGP-Vision 3D-CMM. Also I’m used to deal with Go-NoGo, IµM, OµM, Alexometers & Analog-Hardware to evaluate Customer’s WPs specs: that’s means TQM, that is not easy to achieve!

I´m sure my commitment with durable goods, design project skills and also my patient, persistence and perseverance will let me to be able, fulfill and successfully face up any future challenge that the “Metrologist” position will require In future.

Additionally, I offer excellent analytical abilities and strong problem-solving skills. These qualities, combined with my flexibility and dedication, should enable me to make a good contribution to our customers if shared this great opportunity. Is my wish to hold a little interview with you and lengthen any wonder you could have regarding my CV

My availability is actually inmediately.

BIEMH-2006 Gagemax, Prismo MPS-Std and Scanmax Unloading&Installation.

Looking forward to hearing your positive feedback soon
