Dynamic Analysis of Wind Farm Using Induction Generator Wind Turbines
The vast majority of wind turbines that are currently being installed use one of the three main types of electromechanical conversion system. The first type is known as the Danish concept. The second type uses a doubly fed induction generator instead of a squirrel cage induction generator. The third type is called the ‘direct-drive wind turbine’ because it does not need a gearbox. In this paper...
متن کاملDynamic characterization and predictability analysis of wind speed and wind power time series in Spain wind farm
The renewable energy resources such as wind power have recently attracted more researchers’ attention. It is mainly due to the aggressive energy consumption, high pollution and cost of fossil fuels. In this era, the future fluctuations of these time series should be predicted to increase the reliability of the power network. In this paper, the dynamic characteristics and short-term predictabili...
متن کاملAnalysis and simulation of dynamic performance for DFIG-based wind farm connected to a distrubition system
Local renewable resources such as wind and solar are often available in remote locations. Wind farms consist of many individual wind turbines which are connected to the electric power transmission network. A wind farm can use the wind resources from a certain area efficiently. Double-fed induction generator (DFIG) is a generating principle widely used in wind turbine (WT). DFIG are ab...
متن کاملWind Farm Optimization
This paper will formulate integer programs to determine the optimal positions of wind turbines within a wind farm. The formulations were based on variations of the vertex packing problem. Three formulations are presented, which seek to maximize power generated in accordance with constraints based on the number of turbines, turbine proximity, and turbine interference. These were in the form of b...
متن کاملWind farm worries
The report also highlights the use of smallpox in bioterrorism as a particularly worrying threat. Authorities around the world should work together to combat the kind of bioterrorism that occurred with the letters warning of anthrax after September 11 2001, it says. A flu pandemic would affect more than 1.5 billion people, or 25 per cent of the world's population. Even if the disease was mild i...
