In the United States, the development of biofuels has been presented as a potential way for America to become less dependent on foreign oil, while at the same time reducing greenhouse gas emissions. Both of these potential benefits are appealing, but the feasibility of biofuels, from both scientific and economic perspectives, is still an open question and much debated. In December, President Bu...

Recent developments in the design and manufacture of microcomputers together with improved simulation techniques make it possible to achieve the speed and accuracy required for the dynamic simulation of power systems in real time. This paper presents some experimental results and outlines new ideas on hardware architecture, mathematical algorithms and software development for this purpose. The ...

In the present era, faults are the greatest interruption for the power system utility. Theses, faults on electrical power systems are unavoidable problems and will continue to happen. These faults are effects on the power system reliability and stability, hence, diagnosis and classification of such faults in rapid and accurate way is an important issue. In this paper, combination method of digi...

When power systems are expanded and connected together with weak tie lines, the low-frequency oscillations are increased and the stability margin of the power system decreases. Therefore, when designing the transmission system to be used, it is necessary to maintain the dynamic stability of the power system, and to make sure to have the most possible stability margin. SSSC is a FACTS device con...

Monitoring and supervision of overhead power lines have become essential actions in Electrical Power Systems since the introduction Smart Grid concept. In order to monitor lines, simple non-invasive devices are mounted on support poles, which detect line abnormalities faults by measuring magnetic field originating from conductors. Measured signals also used determine various electrical non-elec...

Transmission and distribution lines are vital links between generating units and consumers. They are exposed to atmosphere, hence chances of occurrence of fault in transmission line is very high, which has to be immediately taken care of in order to minimize damage caused by it. This paper focuses on detecting the faults on electric power transmission lines using artificial neural networks. A f...

The present paper presents an accurate hybrid framework capable to rapidly detect, classify & locate shortcircuit faults on transmission lines. The proposed algorithm has employed the values resulted from each threephase currents wavelet transform in order to obtain instantaneous fault detection. Singling out short-circuit faults based on the measured voltage waveforms and three-phase current i...
