[China Aluminum Industry Network] Aluminum is the first non-ferrous metal, and its output is second only to steel in all metals, but its production consumes a huge amount of electricity. In 2006, China produced 9.35 million tons of electrolytic aluminum and consolidated AC power consumption was 417.71 billion kilowatts. At the time, the total power consumption was 137.2 billion kilowatts, accounting for 4.9% of the total electricity consumption in the country, and the total output value was less than 1% of the national GDP. Therefore, electrolytic aluminum has become a leading high-energy-consuming industry, with electricity sources and guaranteed supply. Is the lifeblood of the electrolytic aluminum industry.

In recent years, with the continuous rise in coal prices and the implementation of the “energy saving and emission reduction†policy imposed by the government on the implementation of high-energy-consuming industrial policies, the electricity price of the electrolytic aluminum industry is higher than the ordinary electricity price, resulting in a substantial shrinkage of industry profits, from a long-term development perspective. Look, the continuing trend of rising electricity prices will continue. Under this situation, actively exploring new sources of electric power sources in the electrolytic aluminum industry will have even more universal and long-term effects. Wind power generation is an important part of the new energy industry. China has abundant wind energy resources. There are abundant wind energy resources in the vast areas of the coastal areas, northeast, northwest, and inland hinterland in the hinterland of the electrolytic aluminum enterprises. Direct purchases of electricity generated by existing wind turbines are not feasible because their on-grid tariffs are much higher than the existing coal power.
The relatively new invention technology of the combined wind power generation wind turbine generating unit combined wind wind turbine unit is to divide the wind split wind turbines (hereinafter referred to as the sub-wind turbines) in the shape of multiple long rhombuses into a joint arrangement. Both sides of each long rhombic unit set at an interval may form a wind-conducting passage formed by the sub-window compartments and the winds that affect each other to form a wind, thereby forming a mutual gathering wind effect. However, the blades of the vertical double paddle wheel wind turbines are juxtaposed in the gathering wind passageway, so that the concentrated wind force continuously tangentially impacts the larger moment of the paddle wheel wind wheel and promotes the rotation to form a larger output capacity conversion.
The “separate fan group†is composed of vertical twin paddle wheel wind wheels meshing with each other, and can be united with each other through the parallel arrangement of the units, so that several units can achieve the integrated linkage force output situation. The equipment room (separate fan chamber) can be naturally formed by two-way combination of diamond-shaped wind slopes. The sub-housing compartment is a completely fixed form facing the wind direction. Its wind method is a feature that uses the natural wind path to move back and forth in a straight line. It adapts to the overall change of the wind direction through the adjustment of the direction of the positive and negative rotation of the paddle wheel, due to the wind The channel has a downwind effect, and the paddle wheel has no special strict requirements on the wind direction. Therefore, if the wind direction deviates from the main line direction at a small angle or so, it will not have any impact on the unit operation; it passes the “wind separation, wind gathering, linkage output. The combined effect of paddle wheel diameter, height, and blade triple design and development capability can make a single machine more than 10 megawatts to 100 megawatts high-power design become a reality, and its “umbrella paddle expansion and contraction control system†can be simple and accurate. The overall control of paddle wheel wind turbines is achieved by quickly and effectively adjusting the reach of each blade to realize the control of the start of the breeze, wind adjustment and brake force reduction, and eliminate the influence of the typhoon effectively, which is achieved through the parallel arrangement and control of multiple generator sets. The unit can make full use of the breeze and strong wind to generate electricity, which can realize integration of many new advantages such as high-power and low-cost maintenance, and can form different Specifications power series products.
The generated wind power is directly sent to the electrolytic aluminum enterprise. Wind power is integrated into the national public power grid. Transport is the usual practice for power transmission. However, it is technically difficult, the control is difficult to implement, the equipment costs are high, and the departments involved are numerous. In addition, compared with the power indicators of the public power grid, the power index requirements applied to the electrolytic aluminum industry are unique, such as frequency requirements, HVDC transmission, etc., and their indexes can be greatly reduced. Therefore, separate construction of wind power plants and electrolytic aluminum enterprises is adopted. The large-scale direct transmission of power transmission between the transmission lines has many outstanding advantages and long-term benefits. The “joint wind turbine unit†with mature and perfect prospects and benefits has provided a solid technical capacity guarantee for the aforementioned scenarios. After the completion of the construction, the wind power plant can be operated under “substantially no cost†for a long time; it can make wind power available on the Internet. The price of electricity is lower than that of coal-fired electricity; and the design method of “transmitting wind power directly to the electrolytic aluminum enterprise†not only provides a more practical and feasible implementation guarantee, but also further reduces the price of electricity. China is a major producer and exporter of electrolytic aluminum. If large-scale electrolytic aluminum enterprises in China adopt wind power without any consumption and pollution emissions, it will not only be a basis for long-term huge gains, but also significantly increase product competitiveness, and it can also achieve “11. V. The overall goal of energy conservation and emission reduction has made incalculable contributions.
