The power interruption in factories, hospitals, and airports is a critical problem that should be avoided. The solution is uninterruptible power supply (ups) system. Such problem may be solved by introducing solar photovoltaic (PV) or diesel generators (DG)in the ups system. Knowing that the economic problem of providing electrical energy to factories, hospitals, workshops,....etc. may be solve...

The transportation industry consumes about 28% of the total energy consumed by all sectors in the United States. This paper proposes a renewable wind power system (RWPS) as an alternative power source for signalized traffic intersections. The proposed system can be mounted onto the existing transportation infrastructure to provide reliable green electricity. Large-scale implementation of such a...

This paper presents new structures of circuits: adders and D triggers based on the current mode gates – digital elements operating with constant, continuous power supply current. Current mode circuits do not perturb the analogue part of the chip integrated on the same die through the parasitic coupling across the substrate with the same strength as voltage mode circuits do. Designed circuits ar...

Distributed generation with a combustion engine prime mover is still widely used to supply electric power in a variety of applications. These applications range from backup power supply systems and combined wind-diesel generation to providing power in places where grid connection is either technically impractical or financially uneconomic. Modelling of such systems as a whole is extremely diffi...

The paper deals with the problem of design and FPGAbased realization of digital circuits with the current-mode gates – novel digital gates operating with constant, continuous power supply current. The purpose is the provision of a high level of noise immunity of chips, which contain both analog and digital circuits. Using proposed approach to design digital current-mode circuits, the current-mo...

The stand-alone energy system having a photovoltaic (PV) panels or wind turbines have low reliability and high cost as compared with wind/PV hybrid energy system. In this study, Biogeography Based Optimization (BBO) algorithm is developed for the prediction of the optimal sizing coefficient of wind/ PV hybrid energy system in remote areas. BBO algorithm is used to evaluate optimal component siz...

An inventing electrical power generation system is developed by integrating simultaneously solar energy, rains energy, wind energy, charged cloud energy, lightning energy, thunder energy which are assigned as nonconventional or renewable energy sources. All the natural wastage energies are used for production of electricity. Electrical power is accomplished with a minimum cost and pollution fre...

In the summer of 2000, we constructed the four 30-m long straight sections in the SPring-8 Storage Ring. Magnets were rearranged to make long free spaces. New girders were designed, manufactured and installed to the SPring-8 storage ring tunnel. Magnets placed on the girders were aligned on a straight line using CCD camera and laser. A long undulator was installed in one long straight section a...

As the gap between supply and demand of electrical power is getting wider the continuous power supply is not possible for all at the same time. Existing power grid is not well suited for 21 century power flow from generation to end user. To focus on the challenges of 20 century grid like blackout, Power discontinuity, Frequency variation, etc. the new concept of smart grid emerged. It is expect...
