A New Way to Solve the Problem of Power Supply in Electrolytic Aluminum Industry——Wind Generator

2018-07-13 13:37:39

Aluminum is the first non-ferrous metal, and its output is second only to steel in all metals, but its production consumes huge amounts of electricity. In 2006, China produced 9.35 million tons of electrolytic aluminum, and the integrated AC power consumption was 1467.1 billion kWh. 137.2 billion kilowatts, accounting for 4.9% of the country's total electricity consumption, while the total output value is less than 1% of the national GDP, so electrolytic aluminum has become a leading high-energy-consuming industry. The source of electricity and guaranteed supply are 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 state to limit the implementation of high-energy-consuming industrial policies, the price of electricity in the electrolytic aluminum industry has been higher than that of ordinary electricity prices, resulting in a sharp decline in industrial 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 latest invention technology of combined wind power generating unit using combined wind special high-power wind generating unit is to divide multiple wind-shaped wind turbines (hereafter referred to as sub-wind turbines) in the form of long rhombuses and arrange them in parallel. Both sides of the long rhombic units located adjacent to each other may form a wind-conducting passage formed by the sub-window compartments that separate winds and affect each other to form a wind, 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 gathering wind force continuously and tangentially impacts the maximum moment of the paddle wheel wind wheel and pushes it to rotate to form a maximum 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 unit that is arranged side by side, so that several units can realize the integrated power output situation of joint linkage. The equipment room (separate fan cabin) can be naturally formed by two-way merging 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 operation of the unit; it passes the “wind and wind convergence, 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, through which the “umbrella paddle expansion 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, and other indicators, which can be significantly reduced, so the separate construction of wind power plants and electrolytic aluminum companies 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 can also achieve “11. V. The overall goal of energy conservation and emission reduction has made incalculable contributions.
