Building a Wind Turbine

The first step in building a wind turbine is setting up the tower where the fiberglass nacelle is installed. The nacelle is a strong, hollow casing that contains the inner workings of the wind turbine. Usually made of fiberglass, the nacelle contains the main drive shaft and the gearbox. Its inner workings also contain blade pitch and yaw controls. The nacelle is assembled and attached onto a base frame at a factory.

The most diverse use of materials and the most experimentation with new materials occur with the blades. Although the most dominant material used for the blades in commercial wind turbines is fiberglass with a hollow core, other materials in use include lightweight woods and aluminum. Wooden blades are solid, but most blades consist of a skin surrounding a core that is either hollow or filled with a lightweight substance such as plastic foam or honeycomb, or balsa wood. Wind turbines also include a utility box, which converts the wind energy into electricity and which is located at the base of the tower. The generator and wind powered street lights are standard equipment whose main components are steel and copper. Various cables connect the utility box to the nacelle, while others connect the whole turbine to nearby turbines and to a transformer.

Potential Positive and Negative Effects of Wind Solar Power System.There are a variety of potential positive and negative impacts of wind powered technology.

Potential positive impacts include:Wind energy is friendly to the surrounding environment, as no fossil fuels are burnt to generate electricity from wind energy.

Wind turbines take up less space than the average power station. Windmills only have to occupy a few square meters for the base; this allows the land around the turbine to be used for many purposes, for example agriculture.Newer technologies are making the extraction of wind energy much more efficient. The wind is free, and we are able to cash in on this free source of energy.

Wind turbines are a great resource to generate energy in remote locations, such as mountain communities and remote countryside.Wind turbines can be a range of different sizes in order to support varying population levels.When combined with solar electricity, this energy source is great for developed and developing countries to provide a steady, reliable supply of electricity.

Potential negative impacts include:Wind turbines generally produce less electricity than the average fossil fuelled power station, requiring multiple wind turbines to be built.Wind turbine construction can be very expensive and costly.

Wind turbines can have a negative impact to surrounding wildlife during the build process.

The noise pollution from commercial wind turbines is sometimes similar to a small jet engine.Protests and/or petitions usually confront any proposed wind farm development.

The rule of thumb for a wind turbine

The result: greater energy production yield and lowest ownership cost.

Design Features

Advanced over-speed control mechanism vs. old style furling

Problems with old style furling:

Old style furling works well in an ideal, wind tunnel test environment. Realistically, wind speed and wind direction changes frequently and mechanical furling doesn't have instantaneous response to actual changes of wind status. Especially in bad weather conditions, small wind turbine furling components wear out quickly, therefore, increases maintenance costs and shorten wind turbine service life or causes system failure.

Most of old style furling based wind turbines have three moving parts. It is the moving parts for mechanical over-speed protection that wear out and require a lot of maintenance. Operation of furling based wind turbines would lead to mechanical abrasion, cause vibration, malfunction, and failure of the wind turbine and other devastating results in the long run.

The rule of thumb for a reliable wind turbine generator is that the fewer the moving parts, the more reliable the wind turbine is.

Windmax Solution:

Windmax H series adopted Innovative over-speed control so it improves the reliability by abandoning the moving parts for mechanical over-speed protection and minimizing the moving parts to only two.

Innovative over-speed control design of the Windmax H series:

Windmax H series speed limitation abandoned the traditional failure-prone mechanical furling Wind Solar Power System and solved safety and reliability problems facing most small wind turbines. Advanced speed limitation of Windmax H series is achieved through advanced electromagnetic speed limitation supplemented by aerodynamic speed limitation by blade deformation. Electromagnetic braking is used in combination with Aerodynamic braking to reduce the rotational speed of the generator.

Wind Solar Power System is very useful

Energy is the material basis of social activities. In the 21st century, human society is facing a shortage of fossil fuels and the environment polluted situation, the era of cheap oil is over, and gradually change the energy consumption structure, vigorously develop renewable energy, take the road of sustainable development, new energy development and utilization of human consensus.

Solar energy is a clean, natural renewable energy, inexhaustible. Development and use of solar energy, both air pollution does not appear, it will not affect the ecological balance of nature, and as long as the sun reach the place, has solar energy can be utilized for its long-term nature of solar energy, renewable, non-polluting, etc. much people of all ages. At the same time, in today's world, conventional energy gradually reduced, while the world population growing year by year, the rapid development of science and technology in the near future, existing energy conversion systems will inevitably transform into a new source of energy. Energy is an important national economic development and people's living material basis necessary. In the past 200 years, based on coal, oil, natural gas and other fossil fuel-based energy system on a great impetus to the development of human society. But the human use of fossil fuels, but also poses a serious environmental pollution and ecosystem destruction. States have started according to national circumstances, governance and mitigation has been deteriorating environment and renewable, non-polluting development and utilization of new energy sources as an important part of sustainable development. Wind and solar power generation system is the use of wind and solar energy resources complementary, with the higher cost of a new energy system, with good prospects.

Wind and solar power generation systems in recent years attracted the attention of many experts and scholars, but also made ​​certain achievements, and has been extended to the daily life in the past. Wind Solar Power System, make full use of the green clean energy, to achieve zero power consumption, zero emissions, zero pollution, products widely used in roads, landscape, residential lighting and surveillance, communications base stations, ships and so on. By studying the results, as the full use of the system of two new energy, wind turbine is more suitable for the present needs.
