About this Training Course Wind has surpassed hydro-power generation in many countries recently. Wind energy offers many advantages, which explains why it's one of the fastest-growing energy sources in the world. The following are the advantages of wind power: Wind power is cost effective: Land-based utility-scale wind is one of the lowest-priced energy sources available today The fuel for wind power is free. This reduces the operation and maintenance cost of wind power plants significantly Wind is a clean source of power generation that does not pollute the air like power plants which rely on combustion of fossil fuel Wind power plants create jobs. Wind turbine technician is the fastest growing career in many countries Wind enables industry growth and competitiveness due to its low cost Wind power is a domestic source of energy. The wind supply is abundant and inexhaustible. The wind power generation capacity has become the largest source of renewable power in many countries Wind turbines can be built on existing farms and ranches. This greatly benefits the economy in rural areas, where most of the best wind sites are found. Wind power plant owners make rent payments to the farmers or ranchers for the use of their land, providing landowners with additional income This 5 half-day course covers all aspects of wind power plants including evaluation of a potential location for a wind power plant using wind data and using statistical distributions to approximate available wind energy at a wind power plant site. It provides also an in-depth understanding of all wind power plant equipment including wind turbines, generators, instrumentation and control systems, drive trains, gearboxes, doubly fed induction generators, synchronous generators, nacelles, towers, transformers, etc. The economics of a wind power plant including economic analysis of wind power generation, economic comparison between a large- and small-scale wind power plant, economic decision making, rate of return from a wind power plant, economic life and replacement of a wind power plant as well as the cost of electricity from wind power plants are covered in detail in this course. A thorough explanation of the design, operation and maintenance of on-shore and off-shore wind farms is presented in detail in this course as well as all the significant improvements that have been made to wind power generating plants during the last two decades.
