In nature, it is solar power that creates wind power. Consider the example of the sea breeze. The sun heats both land and sea, but the land heats up more quickly and reaches a higher temperature than the sea. The air over the land becomes hotter than the air over the sea and the hot air rises, creating an area of lower air pressure (close to the surface). Air moves from the area of higher pressure over the sea to the area of lower pressure over the land. The cool sea air heats up as it moves over the land and so it rises, creating a cycle. The ....etc

Definition

The most important development in the computer communications industry in the 1990s is the evolution of the integrated services digital network (ISDN) and broadband ISDN (B-ISDN). The ISDN and B-ISDN have had a dramatic impact on the planning and deployment of intelligent digital networks providing integrated services for voice, data and video. Further, the work on the ISDN and B-ISDN standards has led to the development of two major new networking technologies; frame relay and asynchronous transfer mode (ATM). Frame relay and ATM ....etc

Modems and ISDN

The modern telephone system is designed to carry the sound of a human voice talking normally. The engineers save money by cutting out the high a low pitch sounds that occur only in music, or sounds that last for a very short period of time. Modems convert data into sound so that it can be sent through the phone system. Just as the telegraph sent data by alternating dots and dashes, the earliest modems sent data by alternating the sound on a phone between two tones. However, modern m ....etc

ABSTRACT

The demands made on the surface quality and thickness of steel strip have increased in recent years. At the same time, operators have had to concentrate on maintaining high annual production rates. To balance these needs, plants have to be equipped with advanced electrical s ....etc

A variable-speed controller, for an existing 225 kW fixed-speed wind power generator, is presented in this paper. A sensorless direct torque control algorithm-based controller is proposed for the squirrel-cage induction generator. Generator torque reference is derived based on sensorless maximum power tracking mode algorithm, up to the base speed of the generator. A three-phase front-end converter is used here to deliver the generated power to the grid with unity-power-factor operation at all wind speeds. This algorithm is based on direct activ ....etc

ENHANCED PERFORMANCE OF A DOUBLY FED
WIND-POWER INDUCTION GENERATOR AT WIND-
RANGE BOUNDARIES
ABSTRACT
The doubly fed induction generator (DFIG) is one of the largest generators used
with MW-class wind turbines. This paper focuses on the weak performance areas
of grid-connected DFIG-based wind turbines. Basically, the DFIG performance at
low wind speeds, close to the cut in speed, and around the full rating operation (in
the vicinity of rated wind speed) is investigated. For low wind speed region, the

A large interest in renewable energy systems has been developed to mitigate the green house effect. In Western Europe, the focus is thus, on wind power and especially on offshore locations, due to higher energy production, a longer expected life time and lack of suitable wind turbine sites on land. A DC cable is the preferred choice when connecting large offshore wind farms to the grid. The utilization of the Dc cables was enabled by the new HVDC transmission technology using voltage sourced converters. The offshore windfarms that are being bui ....etc

Today, nuclear plants employ multiple safety systems which alone account for about a quarter of the capital costs. What about solar and wind energy for electricity generation?, asks Melford Ita.

Main image: Solar energy is environment friendly; silent, requires no fuel and does not pollute

Inset: Germany leads the world in wind energy generation and applications

With growing concerns over the potential hazard of a nuclear accident, spent fuel management and the fortuitous release of radioactive materials, it is wise to debate the r ....etc
