Recently, the Ministry of industry and information technology and the State Administration of quality inspection jointly issued the notice on organizing and implementing the motor energy efficiency improvement plan (2013-2015), which is proposed to organize and mobilize the whole system power for three years, and comprehensively improve the motor energy efficiency from the field of motor production, application and recycling and remanufacturing through policy guidance, standard restriction, supervision and prosecution and market-oriented operation mechanism, Promote the transformation and upgrading of the motor industry.
According to the data provided by the Ministry of industry and information, the efficiency of the motor (
Dc Motor) system can be improved by 5-8 percentage points in the whole by promoting high-efficiency motor, eliminating the in use low efficiency motor (
DC Motor), making efficient remanufacturing of low efficiency motor (DC motor), and matching energy saving transformation of motor (DC motor) system according to its load characteristics and operating conditions, The annual energy saving is 1300-230billion kwh, which is equivalent to the power generation of Two Three Gorges power stations.
The efficiency of motor (DC motor) system is greatly improved
According to statistics, in 2011, the total electric power consumption of China's electric motor (DC motor) is about 1.7 billion kilowatts, with the total consumption of about 3trillion kilowatt hours, accounting for 64% of the total electricity consumption of the whole society, of which the total electric power consumption of the motor in the industrial field is 2.6 trillion kwh, accounting for 75% of the industrial power consumption.
At the Forum on innovation and development of Chinese electrical equipment held recently, industry insiders also told reporters that motor (DC motor), and system energy saving have been considered the most potential area of energy saving and consumption reduction in China. The efficiency of motor (DC motor) in China is only 87%, while the developing country has reached over 91%, and the United States has reached 93%, There is a huge space for energy saving in the motor (DC motor) industry in China.
In fact, with the support of national policies, the energy efficiency of motor (DC motor) in China has been gradually improved in recent years, but the overall energy efficiency level is still low. From the motor itself, the average level of motor efficiency in China is 3-5% lower than that of foreign countries, and the current high efficiency motor (DC motor) is only about 3%; From the view of motor system, the operating efficiency of motor system is 10-20% lower than that of foreign advanced level due to unreasonable matching and backward adjustment mode. The large use of low efficiency motor (DC motor) causes huge waste of power. Every percentage point of the increase in the energy efficiency of electric motor in the industrial field can save about 26billion kilowatt hours of electricity per year.
Facing the development environment of tight resource constraints, the major 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 classification standard for motor energy efficiency and unified the test methods; The United States has been implementing high efficiency motor (DC motor) from 1997, and in 2011, it has also enforced super high efficiency motor; Europe also began to enforce efficient motors (DC motors) in 2011.
The reporter learned that in 2006, China issued the energy efficiency standard for motor (DC motor) (gb18613-2006), which has been revised in recent years according to IEC standard organization. The new standard (gb18613-2012) was officially implemented on September 1, 2012. According to the new national standards, most of the motor (DC motor) products produced in China are not efficient (high efficiency motor (DC motor) refers to the motor (DC motor) which meets or exceeds the energy saving evaluation value in gb18613-2012 standard). In order to accelerate the energy saving and consumption reduction of industry, we must vigorously improve the energy efficiency of the motor (DC motor).
Energy efficiency improvement of motor system is a comprehensive project
The motor energy efficiency improvement plan (2013-2015) clearly proposes that by 2015, the motor (DC motor) products will be upgraded and replaced, 50% of the low voltage three-phase cage asynchronous motor products and 40% of the high voltage motor products will meet the energy efficiency standard specification of the high-efficiency motor; The company has promoted 170million kW of high-efficiency motor (DC motor), eliminated 160 million kw of low efficiency motor in use, implemented energy saving technical transformation of 100million kW of motor system, and implemented elimination of motor to produce 20million kW.
Zhuzetang, 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 suitable for working condition and making the system run in high efficiency zone forever and motor itself is also in high efficiency zone can be called energy-saving motor. Whether to implement the contract energy management mode is also an important indicator to measure energy-saving motor.
Experts pointed out that energy saving and consumption reduction and reliability improvement of the motor industry are complementary. There is still a huge gap between the reliability of motor in China and developed countries. There is a huge space for improvement in design, material, technology, testing and other aspects.
Chen Weihua, director of National Center for medium and small-sized motor (deceleration motor) and system engineering technology research center, said that the energy saving project of motor (deceleration motor) system is a complex system energy saving project which considers various factors such as motor body, driving equipment, control motor, pipe network system and various subsystems and parts with the best or better matching. The energy saving engineering technology of motor (deceleration motor) system is a comprehensive engineering technology which can design, manufacture and select appropriate system components and match them reasonably on the premise of satisfying the load requirements first, so as to achieve the best or better comprehensive engineering technology for the comprehensive energy saving effect and system cost performance.
Industrial policy is continuously launched
"The organization and implementation of the energy efficiency improvement plan of motor (deceleration motor) determined five main tasks: accelerating the promotion of high-efficiency motor (deceleration motor), eliminating low efficiency motor (deceleration motor), implementing energy saving technology transformation of motor system, implementing high-efficiency remanufacturing of motor and accelerating technology research and development and Application demonstration of high-efficiency motor (deceleration motor), It is another important blow to promote energy conservation and emission reduction of motor (deceleration motor) and motor system. " A person in charge of Dalian motor group www.sc-motor.cn/ Tell the reporter.
The reporter combed and found that the implementation plan of 2013 special action on industrial energy conservation and green development issued by the Ministry of industry and information in April of this year determined two special plans to promote the implementation of motor energy efficiency improvement and lead related green development. 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 efficient energy-saving fans, pumps and air compressors.
Wangqiushi, a consultant researcher of sedi, believes that the 12th Five year plan proposes to vigorously develop seven strategic emerging industries, while the motor (deceleration motor) industry, as the leading industry of energy conservation and environmental protection, new energy, new energy vehicles and high-end equipment manufacturing, is inevitably supported by national policies.
Relevant personnel of the Ministry of industry and information technology also revealed that the competent departments actively encouraged the contract energy management mode, and let professional energy-saving companies help the motor (deceleration motor) enterprises to carry out energy-saving transformation. The next step will be to establish cooperation platform, introduce third-party institutions and introduce capital market, Promoting the contract energy management mode plays a more important role in the transformation and upgrading of the motor (deceleration motor) industry.
