A few days ago, the Ministry of industry and information technology and the State Administration of quality supervision, inspection and Quarantine jointly issued the notice on organizing and implementing the motor energy efficiency improvement plan (2013-2015), which plans to use three years to organize and mobilize the whole system to comprehensively improve the motor energy efficiency in the fields of motor production, application, recycling and remanufacturing through policy guidance, standard constraints, supervision and prosecution and market-oriented operation mechanism, Promote the transformation and upgrading of the motor industry.
According to the information provided by the Ministry of industry and information technology, the overall efficiency of the motor (
Dc Motor) system can be improved by 5-8 percentage points through the promotion of high-efficiency motors, elimination of low-efficiency motors (DC motors), efficient remanufacturing of low-efficiency motors (DC motors), and matching energy-saving transformation of the motor (
DC Motor) system according to its load characteristics and operating conditions, It can save 130-230 billion kwh of electricity annually, which is equivalent to the power generation of Two Three Gorges power stations.
Large space for efficiency improvement of motor (DC motor) system
According to statistics and calculation, in 2011, China's motor (DC motor) ownership is about 1.7 billion kilowatts, and the total power consumption is about 3 trillion kwh, accounting for 64% of the total power consumption of the whole society, of which the total power consumption of industrial motor is 2.6 trillion kwh, accounting for about 75% of the industrial power consumption.
At the recent forum on innovation and development of China's electrical equipment, industry insiders also told reporters that motor (DC motor) and system energy saving have always been considered as the areas with the greatest potential for energy saving and consumption reduction in China. The efficiency of motor (DC motor) in China is only 87%, while that in developed countries has reached more than 91%, and that in the United States has reached 93%, China's motor (DC motor) industry has a huge space for energy saving.
In fact, with the support of national policies, the energy efficiency level of motor (DC motor) in China has gradually improved in recent years, but the overall energy efficiency level is still low. From the perspective of motor itself, the average level of motor efficiency in China is 3-5 percentage points lower than that in foreign countries, and the high-efficiency motor (DC motor) currently in use only accounts for about 3%; From the perspective of motor system, the operation efficiency of motor system is 10-20 percentage points lower than that of foreign advanced level due to unreasonable matching and backward adjustment mode. The extensive use of low efficiency motor (DC motor) results in huge waste of electricity. Every percentage point increase in the energy efficiency of motors in the industrial field will save about 26 billion kilowatt hours of electricity annually.
Facing the development environment of tight resource constraints, the main developed countries in the world take improving the energy efficiency of motor (DC motor) as an important energy saving measure. In 2008, the International Electrotechnical Commission (IEC) formulated a global unified motor energy efficiency classification standard and unified test methods; In the United States, high-efficiency motor (DC motor) has been enforced since 1997, and super high-efficiency motor has been enforced since 2011; In 2011, Europe also began to enforce the implementation of high efficiency motor (DC motor).
The reporter learned that China issued the energy efficiency standard for motor (DC motor) (gb18613-2006) in 2006, which has been revised in recent years with reference to IEC standard organization. The new standard (gb18613-2012) has been officially implemented on September 1, 2012. According to the new national standard, the vast majority of motor (DC motor) products produced in China are not efficient (efficient motor (DC motor) refers to the motor (DC motor) that meets or surpasses the energy-saving evaluation value in the standard of gb18613-2012). In order to speed up the promotion of industrial energy saving and consumption reduction, we must vigorously improve the energy efficiency of motor (DC motor).
Energy efficiency improvement of motor system is a comprehensive project
The motor energy efficiency improvement plan (2013-2015) clearly puts forward: by 2015, the motor (DC motor) products will be upgraded, 50% of the low-voltage three-phase cage asynchronous motor products and 40% of the high-voltage motor products will meet the energy efficiency standards of high-efficiency motor; It has promoted 170 million kilowatts of high efficiency motors (DC motors), eliminated 160 million kilowatts of low efficiency motors in use, implemented 100 million kilowatts of energy-saving technical transformation of motor system, and eliminated 20 million kilowatts of high efficiency motor remanufacturing.
Zhu Zetang, chairman of Hubei Huabo Motor Co., Ltd., said that high-efficiency motor (DC motor) is not equal to energy-saving motor, but energy-saving motor must be high-efficiency motor. Only the motor which is suitable for working conditions and makes the system always run in the high-efficiency area, and the motor itself also runs in the high-efficiency area, can be called energy-saving motor. Whether the contract energy management mode can be implemented is also an important index to measure the energy-saving motor.
Relevant experts pointed out that the energy saving and consumption reduction of the motor industry and the improvement of its reliability complement each other. There is still a huge gap between China and developed countries in terms of motor reliability. There is a huge room for improvement in design, materials, technology, testing and other aspects.
Chen Weihua, director of the National Research Center for small and medium sized motor (decelerated motor) and system engineering technology, said that the motor (decelerated motor) system energy-saving project is a complex system energy-saving project that comprehensively considers many factors, such as motor body, driving equipment, motor control device, pipe network system and the best or better matching among subsystems and components. The energy-saving engineering technology of motor (reduction motor) system is a comprehensive engineering technology that designs, manufactures and selects the appropriate system components on the premise of meeting the load function requirements first, and matches them reasonably, so as to achieve the best or better comprehensive energy-saving effect and cost performance of the system.
Industrial policies continue to be launched
"This time, we organized and implemented the energy efficiency improvement plan of motor (reduction motor), and determined the main tasks of accelerating the promotion of high-efficiency motor (reduction motor), eliminating low efficiency motor (reduction motor), implementing energy-saving technical transformation of motor system, implementing high-efficiency remanufacturing of motor, and accelerating the R & D and application demonstration of high-efficiency motor (reduction motor), It is another heavy blow to promote energy conservation and emission reduction of motor (reduction motor) and motor system. " A person in charge of Dalian electric machinery group www.sc-motor.cn/ Tell reporters.
The reporter found that the Ministry of industry and information issued the "2013 industrial energy saving and green development special action implementation plan" in April this year, which determined to focus on promoting the implementation of two special plans: the improvement of motor energy efficiency and the green development of lead related industries. Previously, in November 2012, the Ministry of finance, the national development and Reform Commission and the Ministry of industry and information technology issued subsidy policies on high-efficiency and energy-saving fans, water pumps and air compressors.
Wang Qiushi, consultant researcher of CCID, believes that seven strategic emerging industries are proposed to be vigorously developed in the 12th Five Year Plan. As the leading industry of energy conservation and environmental protection, new energy, new energy vehicles and high-end equipment manufacturing, it is inevitable that the motor industry will be strongly supported by national policies.
Relevant people from the Ministry of industry and information technology also revealed that the competent authorities actively encourage the contract energy management mode, and let professional energy-saving companies help motor (reducer) enterprises to carry out energy-saving transformation. The next step will be to establish a cooperation platform, introduce third-party institutions, and introduce the capital market, Promote the contract energy management mode to play a greater role in the process of transformation and upgrading of motor (reducer) industry.
