Power equipment energy saving: policy support space is vast

Guidance: Energy-saving methods have covered the entire industry chain of transmission, transmission, transformation, distribution, and use. The driving factors of energy-saving methods will largely determine the release of downstream demand, such as transformers, high-efficiency motors, and frequency converters.

At present, energy-saving methods have covered the whole industry chain of transmission, transmission, transformation, distribution, and utilization. The driving factors of energy-saving methods will largely determine the release of downstream demand, and thus affect the final promotion effect of this type of energy-saving method.

Amorphous Alloy Transformers: Benefit from the Localization of Amorphous Strips, Expecting Rapid Development

At present, the efficiency of silicon-steel core transformers used in our country is 96%-99.7%. Due to the large number of transformers, the power consumed by the transformer itself is also considerable. At present, all the transformers in China consume 5% to 10% of their electricity. In 2010, the nation's power generation capacity was 41413 billion kWh. The loss of transformers was approximately 207 billion to 414.1 billion kWh, equivalent to 83.63 million to 167.26 million tons of standard coal, and increased carbon dioxide emissions by 22.025 to 4.4050 million tons. In the distribution network losses, transformer losses account for more than 60%. A large number of popular applications of amorphous alloy core transformers not only have significant energy saving effect, but also help reduce environmental pollution.

At present, the proportion of amorphous alloy distribution transformers in the domestic power grid is very limited. In the field of 10KV power distribution in China, the number of S9-type transformers is large, accounting for up to about 83%. The proportion of S11-type distribution transformers is about 15%, and the proportion of SH15 amorphous alloy core distribution transformers is only 1.2%. Therefore, it is expected that in the next stage of rural power grid transformation, amorphous alloy core distribution transformers have a large market space.

During the “Twelfth Five-Year Plan” period, one of the key tasks of the State Grid is to improve people's livelihood and strengthen the construction of distribution networks. It plans to invest RMB 220 billion in a new round of upgrading and upgrading of rural power grids. At the same time, Nanwang’s distribution network construction investment will also increase year by year. The “12th Five-Year Plan” annual average planned investment will be nearly 50 billion yuan, and the total investment amount will be 227.9 billion yuan, accounting for 60% of South China Net's total grid construction investment. It is expected that in the next 5-10 years, amorphous alloy transformers will be used throughout the country and the market has great potential for development. If in accordance with the future of China's new investment in the use of distribution transformers have a proportion of 20% using amorphous alloy transformers, the amorphous alloy transformer market capacity will exceed 100 million KVA. According to industry experts, the market capacity of amorphous alloy transformers in China will reach 100 billion yuan, and the amorphous alloy transformer market will enter a period of high growth.

High-efficiency and energy-saving motors: Subsidy increased, promotion is expected to speed up

China is a large country for the manufacture and use of electric motors, and the electric motor consumes a large amount of electricity each year. In 2010, the electricity consumption of our country's motors was about 2 trillion kwh, which accounted for 60% of the total electricity consumption in the country and 80% of the industrial electricity consumption. At present, China's main production and use of the motor is an ordinary motor, energy efficiency standards in the 3 or 3, the market share of close to 95%, the average efficiency of 87.3%, 3% lower than the efficiency of high-efficiency motor. If all the ordinary motors in use are replaced by high-efficiency motors, at least 60 billion kwh/year will be saved, while the Three Gorges power station will generate 84 billion kilowatt-hours of electricity in 2010. The energy-saving effect of high-efficiency motors is considerable. At the same time, after replacing all ordinary motors with energy-saving motors, it is equivalent to saving more than 25 million tons of standard coal annually and reducing carbon dioxide emissions by more than 50 million tons.

China's motor industry is relatively fragmented and its overall competitiveness is not strong. In 2010, the total motor output of 2,400 motor manufacturing enterprises in China was 220 million kilowatts, and the total output value was over 60 billion yuan. However, only 11 companies had an annual output value of over 1 billion yuan, and 85% had annual production value of less than 30 million yuan. Even so, China's high-efficiency motor industry has formed a relatively complete industrial chain with an annual production capacity of more than 30 million kilowatts. At the same time, China's rare earth resources are abundant, and cold-rolled silicon steel, copper, pure aluminum and other raw materials have strong production capacity, and abundant raw material resources have created favorable conditions for the development of high-efficiency energy-saving motors.

On March 10, 2011, the Ministry of Finance and the National Development and Reform Commission issued the “Notice on Doing a Good Job in Promoting High-Efficiency Motors in 2011”, increasing the subsidies for highly efficient and energy-saving motors, and publishing the second batch of high-efficiency motor products. Promotion directory. Up to now, the National Development and Reform Commission and the Ministry of Finance have announced two batches of high-efficiency motor promotion catalogues, and a total of 9740 specifications and models of motor products have been listed in the promotion catalogue. Among them, the first batch of promotion catalogues included 1061 model products of 14 companies, and the second promotion catalogue included 8409 models of 50 companies.

Inverter: good energy saving effect, wide development space

The frequency converter is a high-tech product with high added value and high return. The initial use of the frequency converter is not for energy saving, but AC drives instead of DC drives and meet the requirements of process control. With the development of automation, power electronics and other technologies, inverters are key equipments for motor speed control and energy saving, which change the old mode in which ordinary motors can only run at constant speed, making the motor and its dragging load without any changes. That is, the speed output can be adjusted according to the production process requirements, thereby reducing the power consumption of the motor and achieving the purpose of efficient system operation.

At present, the energy saving rate of the general frequency converter is about 20%-30%, and the highest frequency may even exceed 50%. The energy-saving effect of the frequency converter is closely related to the operating condition parameters of the application environment. The parameters of the motor operating conditions are reasonable, the characteristics of the load changes, and the initial adjustment and speed control methods of the equipment can directly affect the power saving effect of the inverter. With the rapid development of frequency conversion technology and the expansion of product functions, frequency converters have achieved unprecedented development and application in modern industries such as cement, elevators, printing, and power, as well as medicine, communications, transportation, transportation, electric power, electronics, and environmental protection. All walks of life in the national economy are inseparable from the inverter. According to the 720 yuan/KW price estimate, even without considering the new motor, China's inverter market has reached 73.1 billion yuan, and the development space is very broad.
