Elementary and phase composition as well as micrography of the electric furnace slag were examined. The base of slag is made from phases containing Fe, Mn and Ca. Grains differ in size and shape, they cling together to form bigger or smaller agglomerates, depending on separated fractions. Relative distribution of identified phases in separated fractions is presented and the possibility of phase...

The electric power industry requires qualified personnel to support an optimal and safe operation. Since its beginnings, the IIE has been developing different training technologies and systems for CFE, the main utility for generation, transmission and distribution of electric power in Mexico. Some of these endeavors provide tailored instruction considering trainees traits such as learning style...

In the early 90’s, Jungheinrich was the first company to use static inverters to change the direct current of a forklift truck’s battery into 3-phase AC current, opening the door to the many benefits of AC-power (See Sidebar entitled “Chronology of three-phase AC introduction”). Today, Jungheinrich installs its proprietary AC technology in all its electric truck categories (counterbalanced mode...

Nowadays, the effects of the development of electric power are becoming more and clearer in the development of national economy, and it influences the increased speed of GNP. The generated construction of Electric Power Industry for our country is not very appropriate, and there are a long distance to the international level. First, it discusses the marcocircumstance, the thought of sustainable...

Wastewater discharged from metal-finishing processes usually contains nickel, a hazardous substance that is used extensively in the surface finishing industry. In the present study, an acidic solution containing nickel was treated using strong acid cation exchange resin. A continuous lab-scale cation exchange arrangement permitting the assessment of electric current as an enhancement mechanism ...

The deregulation of the electric industry in the United States opens the power market to competition. Buyers and sellers of electric power will be competing for limited resources. Although regulators will attempt to limit such activity, when large amounts of money are at stake, the participants have incentives to engage in destabilizing behavior. The goal of this study is to model agent driven ...

This paper describes the uses and architecture of a network-centered computing-rich software platform called PowerWeb. PowerWeb was designed and built as a simulation environment for experimentally testing various power exchange auction markets through tournaments. It is designed to host simulations of a competitive “day-ahead” electric energy market in the context of a restructured electric po...

In an electric power system, spinning reserve requirements can be determined by using deterministic and/or probabilistic measures. Although deterministic methods are usual in many systems, application of probabilistic methods becomes increasingly important in the new environment of the electric power utility industry. This is because of the increased uncertainty associated with competition. In ...

In this paper, the basic concepts of dynamic thermal ratings of overhead transmission conductors are discussed. The sensitivity of these ratings with ambient conditions is evaluated. Innovative concepts in the measurement of overhead sag are given and correlated with dynamic rating of overhead transmission conductors. Dynamic transmission line thermal ratings take on increased importance in the...
