Because of the nature of wind, many machines must be installed to intercept a large amount of power. Noise created by gearboxes and blades can be a problem in densely populated areas, and can limit settlement within audible range.
Although wind power sometimes parallels demand, the correlation is unlikely to be perfect. Choosing among the enormous diversity of machines could be a difficult task.
Some previous, very introductory studies of wind resources in the vacinity of Eritrea do exist. It is important to note that the cost estimates given above apply to countries with an installed infrastructure for coal and natural gas, which Eritrea does not have. Another factor that varies among turbines is whether the pitch of the blades is fixed or variable.

Fortunately, there are factors that can be useful guides. Since wind power is an intermittent energy source, some method of storing energy is desirable for high wind penetration systems to ensure adequate supply during peak consumption. This problem can be limited by avoiding known bird migration routes, and perhaps more importantly, locations of known rare and endangered species.
Because of this inherent modularity, increasing or decreasing capacity as needed does not require the outlay of unnecessarily large capital expenditures at any one time. Surveys have shown that uniformity of size and spacing improves aesthetic acceptability considerably Clarke, Countries with limited capital will seek energy supplies with low capital requirements, typically petroleum products.
In addition to wind turbines, which by definition generate electricity, there are also mechanical wind systems used primarily for pumping water. Using these figures, a wind farm which produces power at the rate of an average nuclear power plant about 1 gigawatt may require an area of over 70 square kilometers.
The approximate distribution of the costs of the different components of a wind generation facility are described in the following tables: In particular, power is needed in the central highlands surrounding the capital city of Asmera where about half of the Eritrean population lives.
At this point, birds seem to be the only wildlife adversely affected by wind turbines, and even this disturbance is rarely a problem. First, their large size makes them unsuitable for transportation on small roads.
Other possibilities for future utility-scale wind generation include fly-wheel storage for short term variations or chemical energy storage in the form of hydrogen fuels. Large-scale systems at low wind penetration create fewer problems for wind integration than those with higher penetration.Assessment of Wind Energy Production Software Hermann Reynir Hermannsson A thesis submitted in partial fulfillment of the requirements for the degree of.

negligible as most of the wind farms are equipped with SCADA systems which records turbine performance data in regular time-interval. Such approaches are called as performance monitoring.
In this dissertation, the performance monitoring of wind turbines is accomplished using the historical wind turbine data.
