Energy management system (EMS) architectures are deeply influenced by power system and information system scenarios. The computer industry has been evolving continuously, and the power industry, which remained relatively stable for decades, is now undergoing revolutionary changes that require the special attention of EMS developers. The introduction of new players, the decentralization of production and processing of information, and competition will change the way control centers operate and, consequently, their architecture. Distinct areas of computer science have suggested many different approaches to tackle the problems that arise in the new decentralized scenario. Of particular interest, agent technology, proposed in the context of distributed artificial intelligence, is a very promising approach to support the construction of a new generation of EMS in an open environment.

The power industry is being changed following the deregulation of the electricity generation and power system markets. Competition between numerous utilities leads to the necessity to optimize the operation of power plants and networks, i.e., to decrease the operation costs and to increase the reliability of the equipment. A new generation of simulation and training software workshops is necessary to keep abreast of this evolution. CORYS T.E.S.S. and Tractebel Energy Engineering responded to these new challenges by developing the ALICES software workshop. This article shows that modeling and simulation can contribute to providing the answers to the industry's new challenges. The article begins with an economical justification for simulation and training, focuses on the new generation of simulation software tools, and ends with several case studies to show how the tools are being used in the field.

City streets cover a complex array of underground electric, gas, and communication lines. Effective maintenance, expansion, and new installation of these networks require accurate information regarding the location of the conduits, cables, and other structures that lie beneath the surface. Underground maps, if they exist, are often inaccurate, incomplete, or out of date, and attempts to find underground lines or obstacles using metal locators often prove disappointing. To help companies create accurate maps of subsurface networks, researchers have developed a new ground-penetrating imaging radar (GPIR) system that creates sharp, three-dimensional (3-D) images of underground lines and objects. Schlumberger Corporation, in conjunction with the Electric Power Research Institute (EPRI) and the Gas Research Institute, has developed a GPIR system that detects, locates, and produces 3D maps of underground features. The new underground imaging system holds the potential to reduce utility operating and maintenance costs by avoiding unneeded excavation and by reducing incidences of costly damage such as ruptured gas lines. Field demonstrations in New York City, San Diego, and other utility locations have proven the ability of the new mapping system to create accurate images of objects in crowded urban areas at depths as great as 10 ft (3 m).

As the complexity and diversity of the application of DC and AC motor drives has increased, so too has the occurrence of problems that are often caused by the interaction between the components of the system. The actual problem and its associated concepts are termed the problem domain. Computer simulation of drives provides an economical means of analyzing drive systems in a controlled environment to ensure that the system is stable and operates as required. The means to input, process and extract the data from the simulation is termed the solution domain. This article examines the process of reengineering the CASED drive simulation package so that it can be accessible to engineers whose main forte is electrical machines and drives and who are not simulation specialists. The objective is to bring the solution domain closer to the problem domain.

The advances in relay test sets, personal computers (PC), and the availability of satellite clocks have taken fault-simulated, end-to-end relay testing by secondary injection to new heights. This creative approach to relay testing allows relay technicians and engineers to comprehensively check line relays and evaluate their dynamic response to faults without staging actual faults on energized transmission lines. The testing technique offers flexibility, speed, and accuracy in testing line relays.

Managing risk is central to engineering, to business, and, in fact, to most human endeavors, and computer analysis is central to managing risk. This article gives a broad exposition of risk in the competitive and privatized electric power business. Contrary to much that is being written today, the emphasis of this article is on nonfinancial risks, hazards that are neither measured nor hedged using tools of financial markets. The focus is on practical methods for modeling and managing risk, and real examples are provided.

This paper illustrates how an electric utility can use a sophisticated outage management system (OMS) to improve power system performance by: establishing accurate failure rates and outage times; identifying specific areas that contribute to poor system reliability indexes; using actual data to improve the accuracy of predictive reliability studies; and establishing system performance without the use of costly monitoring systems.

The power of object-oriented programming in a Windows environment has been used to design a software application that automatically generates switching schemes that satisfy specified interlocking criteria. The application has two components, one for generating interlocking schemes from substation data and the other for generating switching instructions and implementing them. The connectivity of substations, parameters of switches and components, and interlocking constraints are used by the software as input data. While this generalised tool expedites the development of interlocking schemes, its use is not limited to specific substation configurations. Three out of the many designs prepared are presented in this paper to demonstrate its usefulness.
