There is still a huge space for energy-saving retrofit of the motor system, and the potential for energy conservation needs to be fully explored. October 14th is the World Standardization Day. At the International Symposium on Frequency Conversion and Energy Saving and Emission Reduction of Motor Systems held on the same day, more than 100 representatives from relevant government departments, standardization agencies, domestic and foreign industry association experts, manufacturers and users In-depth exchanges, the above research and judgment on its current status, at the same time, that the work to improve the overall operating efficiency of China's motor system has a long way to go.
Great energy saving potential
Around the country's top ten energy-saving engineering motor systems to promote energy-saving work is in the ascendant, reducing energy consumption and improving efficiency has become a key word in the motor industry in recent years.
The industry believes that in recent years, the motor system energy-saving project has made effective progress in improving the operating efficiency based on the system adjustment method based on frequency conversion and speed regulation, but in the environment of vigorously developing green economy, its promotion Strength and progress are still insufficient and lacking.
As we all know, the motor system is an important industrial energy-consuming device. According to data from industry associations, the total installed capacity of various types of electric motors in China is about 1.2 billion kilowatts in 2010, and the annual electricity consumption is about 2.5 trillion kilowatt-hours (calculated according to the average annual operation of 2000 hours), accounting for the proportion of electricity consumption in the whole society. More than 60%. To this end, the energy-saving work of the motor system is listed as an important part of China's "energy-saving medium and long-term plan" and "ten key energy-saving projects".
As an important energy-saving technology, the motor system frequency conversion has been widely recognized and promoted by domestic and foreign counterparts due to its remarkable energy-saving effect and short investment return period. According to Sun Xiaokang, deputy director of the National Standardization Administration Committee, compared with the traditional fixed speed motor, the motor system can reduce energy consumption by more than 30% after frequency conversion.
In view of this, the domestic industry is actively implemented. According to Sun Xiaokang, during the 11th Five-Year Plan period, on the basis of updating and renovating a single piece of equipment, the relevant departments will focus on promoting the system adjustment mode based on frequency conversion and speed regulation to improve the system operation efficiency, and form a 36 billion kWh/year festival in 5 years. Electrical ability.
Throughout the national industrial operation situation, the development trend of China's motor industry has generally improved. At present, it has become a major motor producing country and a major exporting country. In recent years, the promotion of energy saving in motor systems has also begun to show results. The industry generally believes that it still has great potential.
According to relevant planning, during the 12th Five-Year Plan period, the average operating efficiency of China's motor system will increase by 2 to 3 percentage points on the current basis, resulting in a power saving capacity of 80 billion kWh/year. Experts predict that by then the national motor system is expected to achieve 400 billion kWh / year of power saving capacity.
This means that the effective transformation of the motor system variable frequency speed regulation will become a key move in the future.
