The height of the wind turbine generally refers to the vertical distance between the fan axis line and the ground. The height of a wind turbine has an important effect on its power generation efficiency and stability. Here are some facts about the height of wind turbines: First of all, the height of the wind turbine is usually about 80 meters to 160 meters. With the continuous progress of technology, the height of some new wind turbines can even reach more than 200 meters. The higher the height of the fan, in general, the greater the power generated. Secondly, the height selection of wind turbines is affected by a variety of factors. One of the main factors is the wind speed at ground level. In general, the lower the wind speed at the ground level, the higher the fan needs to be in order to obtain a larger wind energy resource. In addition, it is also necessary to consider many factors such as terrain, climate conditions, and the surrounding environment. In addition, with the development of wind power generation technology, the fan lifting system is also constantly improving. By increasing the height of the tower, increasing the length of the blade and improving the blade design, the height of the fan is increased, and the power generation efficiency is improved. In addition, the height of the wind turbine will also have a certain impact on the surrounding environment and ecosystem. Therefore, when choosing the height of the fan, it is also necessary to carry out a careful environmental impact assessment and ecological protection measures. In general, the height of wind turbines is a complex system engineering problem that requires comprehensive consideration of many factors. With the continuous progress and innovation of technology, it is believed that the height of wind turbines will continue to increase in the future and make greater contributions to the development of clean energy.

With the improvement of people's awareness of environmental protection and the wide application of renewable energy, we believe that many friends have seen wind turbines during their travels. Today, let us tell you the more details about vertical axis wind turbines. According to the principle of vertical axis wind turbine,The speed of the wind turbine increases rapidly，its power generation rising speed is correspondingly faster, and the power generation curve becomes full. Under the same power conditions, the rated wind speed of the vertical axis wind turbine is smaller than the horizontal axis wind turbine, and the vertical axis wind turbine generates a large amount of electricity when operating at low wind speed. From the mechanical analysis, the higher power of the vertical axis wind turbine, the the longer of the blades, the longer the distance between the center point of the parallel rod and the center point of the generator shaft,the worse the wind resistance ability, therefore, the triangular vector method can make up for some of the above shortcomings. In the structure, we use the design of straight blade and triangular double fulcrum for vertical axis wind turbines, and the main stress points are concentrated in the hub, which solves the problems of blade falling off, breaking and blade flying out. The blades of vertical axis wind turbine form a circle according to the same Angle difference, so the design purpose can reduce the pressure on the center support. In addition, a series of auxiliary equipment such as gear boxes, reduction boxes and transmission devices can be placed on the working platform relatively close to the ground, reducing the weight of the fan itself, reducing the construction and maintenance costs of the fan to a certain extent, and the vertical axis wind turbine can be used in building integration, which is conductive to urban construction. Therefore, the overall performance index is high. If you are interested in vertical axis wind turbines or have any questions, you can leave messages or private messages in the background.

As renewable energy wind energy is more and more concerned by people, recently many friends consult us about medium and small wind turbines on the Internet. We believe that the coverage rate of medium sized and small wind turbines will be higher and higher in the future. The key points to select the midium and small type wind turbines are as follows. 1. Wind turbine blades It is necessary to use high-strength nylon composite material, high strength, good toughness, anti-ultraviolet, anti-corrosion, anti-wind, with good aerodynamic performance . 2. Bearing It needs to be a first-line brand, and such wind turbines have high efficiency, wear-resistant, durable and long service life. 3. Magnetic steel Magnetic steel using rare earth NdFeb permanent magnet, high efficiency and light weight, less energy consumption, large output power. 4.Anti-strong wind tail design It is necessary to have a pre-offset design of the wind turbine tail rudder, so that the automatic alignment of the windward direction, improve the output power while taking into account the adjustment and strong wind protection. 5.Carbon brush and brush ring structure With such a device, the electricity of the wind turbine can be passed from the carbon brush to the brush ring, and the brush ring will draw out the electricity; When the wind turbine rotates, it rotates to solve the problem of cable breakage. 6. Connection method The use of casing connection, high safety, will not occur racing phenomenon, installation is also very convenient.that installing fans in the field is not only technical work, but also physical work. The ease of installation is a boon for field installers.

Wind energy and solar energy as pure renewable green energy, more and more people pay attention to, the complementarities of the two in time and region make the wind-solar complementary power generation system has a good match in resources, wind-solar complementary power generation system is an independent power system with good resource conditions, and wind-solar complementary street light is a significant application of wind-solar complementary power generation system. The wind-solar complementary street light system is to change the grid power supply of traditional street lights into a wind-solar complementary power generation system that converts wind and solar energy into electricity. The system structure block diagram is shown in the figure. The system consists of wind generator set, solar photovoltaic array, rectifier circuit, voltage regulator circuit, unloader and energy-saving street lamp.The overall working principle of the system is as follows: the three-phase AC from the wind generator set is rectified after the DC and the DC from the photovoltaic array is charged after the voltage regulation circuit, and the battery supplies power to energy-saving street lights. From the perspective of power generation and consumption, the system mainly consists of four parts: power generation, power transformation control, power storage and power consumption. The power transfer is shown in the figure.
With the continuous improvement of China's road traffic network, some remote areas have also built roads, but the use of ordinary street lights in these areas requires the laying of special lines, which will consume a lot of manpower and material resources, so the characteristics of independent power supply of wind and solar complementary street lights are very suitable for use in these areas. The power supply of mobile communication base stations, the electricity consumption of remote mountain villages and the electricity consumption of border posts can all be solved by wind-solar complementary power generation technology, so the study of wind-solar complementary street lamps has wide significance.
