In today's deregulated marketplace, simply delivering power to customers is no longer sufficient; utilities must provide a certain level of quality of service and must deliver the commodity safely, reliably, and cost-effectively. Moreover, information traditionally used only within a given utility is now desired by many players, since the integration, consolidation, and dissemination of information both inter- and intra-utility has become a critical part of the deregulation picture. Exponential advances in hardware, software, and communication equipment allow the transportation, storing, and manipulation of vast quantities of data at blinding speed relative to just a few years ago. As a result, utilities have shifted their focus to information technology and automation to optimize operations and improve the bottom line. This article proposes a global approach for the management and control of medium-voltage (MV) networks. The efficiency of this approach is analyzed in terms of quality of service, optimization of investment, optimization of installation, maintenance, and simplification of operation.

This article describes an attempt to create a completely Web-based, platform-independent, power system simulation package with various analyses distributed in a clustered environment. This is done in order to retain many of the existing simulation routines that have already been implemented on multiple platforms while sharing many common facilities and resources. It achieves this by leveraging heavily on the advanced distributed computing technologies and by using the model-view-controller (MVC) concept. Applying this design concept demonstrates the potential and advantages of embracing the Web as the platform for developing and deploying complex power system simulations.

Fully committed to making maximum use of the speed and efficiency of the Internet, the IEEE Power Engineering Society (PES) has made dramatic progress along the information superhighway in the past year. That’s not to say we didn’t encounter the occasional detour and speed bump along the way, but our advancement in electronic services to our members can now be measured in kilometers rather than centimeters.

The drive to use electric energy more efficiently has created a need for an increased level in the quality of power supplied to customers. These customers have turned to advances in power electronics to improve the efficiency of their equipment. In many cases, new and more efficient equipment is also more sensitive to power system disturbances. As these devices become more prevalent in commercial and industrial facilities, the number of individuals requiring an understanding of basic power quality increases. Many existing publications address the individual aspects of power quality, such as harmonics, but few exist that attempt to provide an overview of the most common power quality concerns. Those that do exist are written with power quality professionals as their target audience. C. Sankaran’s Power Quality attempts to cover the most common aspects of power quality and do so in such a way as to be informative to those new to, or outside of, the field. In the preface, Sankaran describes the book as “The Power Quality Do-It-Yourself Book.” For the most part, he has succeeded in writing a very good primer on power quality. The first chapter contains definitions of commonly used terms in the power and power quality industries. However, readers should note that his use of the term power frequency disturbance is not part of the standard nomenclature used by the power and power quality communities. He uses the term to describe “low-frequency phenomena that result in voltage sags

The problem of detecting and locating shorted turns in rotor windings has always been a difficult technological challenge. The winding is completely embedded in the steel, and the turn insulation is not physically loaded until it is subjected to the centrifugal forces produced at rated speed. The problem of detecting shorted turns appears to be very cumbersome. A technique proposed by the Electric Equipment department of Mexico's Electric Research Institute provides the data, at rated rotor speed, to locate the short-circuited windings and the number of short-circuited turns. This technique improves the sensitivity and dependability by means of a statistical process applied to the signal provided by the search coil.

Deregulation of the energy industry has resulted in the emergence of software that coordinates the functions in power systems. The complexity of these vertically split power systems demand stringent requirements from the employed software. As the market rules change, the regulating policies stated by FERC will need incorporation into the software. By using the latest technology and applying software management practices during development, the measurable results include better designs of the software coupled with high quality and performance. A variety of commercially available tools can be used to improve the software development process. Software modeling and configuration management encompasses two key areas in the development life cycle. This article presents an overview of software modeling and configuration management as applied to software development in deregulated energy markets. It outlines the requirements for software quality, various tool features, and challenges ahead in the development of software for deregulated energy markets.

In the software development area, as in most fields of the computer industry, new technologies are trumpeted as revolutionary solutions almost daily, just to disappear silently some time later. This was not the case with open-architecture energy management systems (EMS). About 10 years after their conception, they have proven to be a successful technological approach. But this does not mean that all problems have been solved; in fact, this is a dynamic research area, in continuous evolution and still raising challenges for the near future.

Faced with multiple options for reinvestment in equipment maintenance, what is the best course of action to maximize reliability at minimum cost? The combination of engineering and financial analyses requires complex mathematical modeling; however, the software must be user-friendly to make the operation of the model simple. With this in mind, substantial effort has been put in developing a suitable decision-support tool to address the question of option selection. This article features the program called Risk-Based Asset Management (RiBAM) and its application in the reinvestment decision-making process.
