the 30-year-old Shenzhen Special Economic Zone has become a model of global innovation and a highland of the global competitiveness of Chinese industries. The Shenzhen Special Economic Zone, which was just born in 1980, is still a border town with only two technicians. Today, it has grown into the most innovative international metropolis in the world. In 2008, Shenzhen became the first pilot to create a national innovative city in China. In 2009, there were 42279 patent applications accepted in Shenzhen (only 18 in 1985), including 20520 invention patents. Shenzhen enterprises participated in the formulation or revision of 62 international standards, 103 national standards and 171 industrial standards. At present, Shenzhen has 1044 state-level high-tech enterprises. Huawei, Ping An, Tencent, BYD, Vanke and other enterprises have grown into the most innovative enterprise stars in the world. In particular, Huawei, established in Shenzhen in 1988, has become the world's second largest provider of communication equipment. In 2009, with 1847 patent applications, it ranked second in the world in terms of equipment production, disinfection, resin treatment and various strict requirements for products

the rapid development of young Shenzhen is largely due to the unconventional innovative application of electric energy, the core driving force of modern economic and efficient development. The power supply of Shenzhen increased from 45 million kwh in 1980 to 56.8 billion kwh in 2009, an increase of more than 1200 times, becoming the fourth largest power consumption city in China, while the power consumption per unit GDP of Shenzhen decreased from 1414.8kwh/10000 yuan in 1980 to 677kwh/10000 yuan in 2009. Shenzhen has not only become a model for the efficient application of electric energy in the world in the past 30 years, but also an important innovator in the field of electrical technology in the world. As early as may, 2001, Emerson Electric, the world's leading manufacturer of electrical technology, purchased all the shares of Shenzhen Ansheng electric at a high price of 750million US dollars. Today, BYD, Zhongju Leitian and Wuzhoulong in Shenzhen have become outstanding representatives of world innovation in the field of electric vehicles. BYD, Kelu electronics and haoningda have become important innovative forces in the field of smart electricity and new energy. The frequency converter industry cluster in Shenzhen, represented by NVIDIA, is also in a pivotal position in the world

at the beginning of November, the young electrical innovation city Shenzhen will usher in the largest ceremony in its history. The evs25 (the 25th World Conference and exhibition of pure electric vehicles, hybrid electric vehicles and fuel cell vehicles) with the theme of sustainable power revolution will be held in Shenzhen. Evs25 will have 2000 delegates and an exhibition area of 45000 square meters. It is an unprecedented and innovative conference to display innovative technologies and products related to electric vehicles. With this grand event, young Shenzhen will enter a new era of electrical technology innovation and application

a model for the application and development of high-efficiency electric energy

Shenzhen has used electric lights for 90 years. As early as the 1920s, electricity entered Bao'an, and an oil-fired generator supplied power for the lighting of Daxin street in Nantou town. In May, 1951, Nantou power plant was put into operation for power generation. The generator is a 112 HP diesel engine, which provides power for County, market town, street lighting and agricultural and sideline products processing. The real meaning of Shenzhen power started in August, 1965. Yuanbao easily caused accidents. The first 35 kV Substation in the history of Anxian county was built and put into operation in wushiyan (xianshiyan). Shenzhen bid farewell to the era of small generators

since the establishment of Shenzhen Special Economic Zone, the power industry in Shenzhen has entered a period of extraordinary development. Over the past 30 years, the annual growth rate of electricity consumption in Shenzhen has exceeded 30% annually. The speed of power development in Shenzhen has strongly supported the average annual growth rate of GDP in Shenzhen by 25.8%

during the period from 2005 to 2009, the new substation capacity in Shenzhen reached 25.052 million KVA, which is more than the sum of the previous 25 years of electricity construction, equivalent to building a new Shenzhen power in five years. In 2007, the power load of Shenzhen exceeded 10million kW, becoming the fourth urban power with a load of more than 10 million kW in China after Beijing, Shanghai and Suzhou, and also the largest power load in the five southern provinces. Today, Shenzhen is not only the fourth largest power consumption city in China, but also has 178 substations of 110 kV and above, with a total length of transmission lines of about 2700 kilometers (including cables), and a power supply load of more than 10 million KW. In 2010, the power supply of Shenzhen will exceed 60billion kwh

Shenzhen electric power has set many domestic records. In 1988, it set a national first in electric automation. The 110 kV Baoan and Nantou substations realized four remote controls of remote control, remote signaling (Communication), telemetry and remote regulation (dispatching), and realized single person on duty. One year later, 110kV AVIC and Lianhuashan substations were unattended. Shenzhen is the first in the country to establish a remote operated automatic power system. Since the beginning of the new century, the first long-distance offshore transmission line crosses Dapeng Bay, and the first power night market in China has been settled in Yantian. The substation with the highest degree of digitization came into being in Nanshan with the development of Shenzhen's high-tech industry

in 2009, the reliability rate of urban power supply in Shenzhen reached 99.968%, and it was rated as one of the five gold medal A-level enterprises in reliability in China. Shenzhen power is the city power with the highest load and the largest power supply volume in southern power, and at the same time, it is the city power with the shortest average outage time of customers, and has become one of the few cities with unlimited power supply in China

in Shenzhen Guangming New Area, Shenzhen electric power canceled the 110 kV voltage level and took the lead in adopting the 220 kV direct voltage drop 20 kV pilot in the country. In the new project, the increased cost in the city is expected to be recovered within 5-8 years, and the substation in the central area will be green transformed in terms of energy conservation, consumption reduction, electromagnetic and noise interference reduction, so as to make the substation more environmentally friendly and closer to the lives of citizens

Shenzhen, a young city, is leading the world in the emerging environmental protection application field of electric vehicles. According to the Shenzhen municipal plan, by the end of 2012, the number of private new energy vehicles in Shenzhen will strive to reach 25000, build 50 bus charging stations, 2500 official vehicle charging piles, 200 social public charging stations and 10000 charging piles, and strive to promote the use of new energy vehicles to a total of 100000 by 2015

Shenzhen recently officially announced local subsidies for private purchases of new energy vehicles. On the basis of the state's maximum subsidy of 50000 yuan for plug-in hybrid vehicles and 60000 yuan for pure electric vehicles, Shenzhen local finance will provide an additional subsidy of 30000 yuan and 60000 yuan for the two vehicles respectively. Shenzhen also stipulates that consumers who use electric vehicles will receive 9000 yuan of electricity subsidies

according to the "2010-2015 electric vehicle charging facilities planning in Shenzhen" recently released by Shenzhen Power Supply Bureau, a total of 89 charging stations and 47500 charging piles will be built in the next two years, with a total investment of about 1.27 billion yuan; At the end of 2015, a total of 150 charging stations and 22.75 charging piles were built, with a total investment of about 4.36 billion yuan
