Smart electricity received another 50billion investment from State Grid in 2011

recently, the first meeting of the second workers' Congress and the 2011 working conference of State Grid Corporation of China closed in Beijing, and the construction of smart electricity has unexpectedly become one of the important tasks of State Grid Corporation of China during the 12th Five Year Plan period

2011 and 2015 are the stage of comprehensive construction of smart electricity in China. At this working meeting, the State Grid Corporation of China refined this development goal and proposed to basically build a strong smart electricity with informatization, automation and interaction characteristics by 2015, forming three synchronous electricity with North China, central China and East China as the receiving end and northwest and northeast electricity as the sending end, so as to improve the resource allocation ability, economic operation efficiency and safety level of electricity The scientific and technological level and intelligent level have been comprehensively improved, and the world-class electricity has been initially built

as the first year of the 12th Five Year Plan, 2011 is also the first year that smart electricity has entered the comprehensive construction stage. The State Grid Corporation of China plans to tilt the investment of 292.5 billion yuan in the operating system universal testing machine of electric and four ball friction and wear testing machine in 2011 to the intelligent construction. It is expected that about 50billion yuan will be used for the intelligent construction in 2011, with a year-on-year increase of 150%. Among them, smart meters are still the main investment object of electric intelligent construction. In the next four to five years, State Grid Corporation of China will invest 46billion yuan in the purchase of smart meters, of which 50million smart meters are planned to be purchased in 2011, an increase of about 11% over 2010. According to the average price of electricity meters of 180-200 yuan/piece, the investment in smart meters in 2011 was about 9-10 billion yuan, accounting for about 20% of the investment in intelligent construction

at the same time, in 2011, the State Power Corporation of China will also complete two batches of pilot projects for the construction of smart electricity, accelerate the promotion of key projects such as smart substations, distribution automation, power fiber to the home, and build a number of comprehensive demonstration projects in Beijing, Yangzhou and other places. Taking advantage of the advantage of power supply at the terminal, Guodian will continue to promote the construction of electric vehicle charging facilities in 2011. According to the basic business model of centralized charging and unified distribution, the layout and construction of charging and replacement power stations will be accelerated. It is expected that 150 charging and replacement power stations will be built throughout the year, and electric vehicle charging and replacement service networks will be built in Beijing, Hangzhou, Tianjin, Hefei, Nanchang and other cities

as one of the core platforms to realize energy conversion and control in the construction of strong smart electricity, at present, China has made major breakthroughs in the research and development of core technologies and the manufacturing of key equipment in smart substations. On January 4, 2010, the 220kV Xijing intelligent substation, the first intelligent substation built by using IOT technology in China, was put into operation in Wuxi, Jiangsu Province. In addition, the newly built and put into operation smart substations of State Grid Corporation of China also include 7 smart substations, including 110kV Beichuan in Sichuan and 220kV Qingdao

according to reports, smart substations are not only an important part of smart electricity, but also an important support for the realization of new energy access to electricity, such as wind and solar energy. As a key technology connecting the six links of intelligent power generation, transmission, transformation, distribution, power consumption and dispatching, intelligent substation can better meet the requirements of intelligent telecommunication, automation and interaction in technology and function. The completion and operation of intelligent substation can greatly improve the intelligent level of equipment and the reliability of equipment operation, realize the automation of unattended and equipment operation, improve the efficiency of resource use and production management, operate more economically, save energy, and use different guide bushings and environmental protection. Take Qingdao 220? Taking kV Wushan substation as an example, compared with the general transformer station, which can meet the use requirements of consumers, the whole life cost can be saved by 22.4 million yuan based on the 15 year service life of the equipment
