Energy science and technology of light 'low-carbon expo' booth a variety of energy saving technology

Shanghai world expo on May 1, 2010 officially opened to meet Chinese and foreign tourists, from around the world 189 countries and 57 actual participation international organization, created the world expo 159 years of history. The theme of the expo is 'city, better life', 'green, low carbon, sustainable' and other environmental elements in the expo got fully reflected on the big stage.

'wind' and 'light' infinite for welcoming the world expo in the expo, the green technology can be seen everywhere, and the biggest bright spot is the mass application of solar energy, wind energy. Park, China pavilion, theme pavilions, expo center, center for performing arts and other major facilities as well as many countries pavilion, both in the form of roof and wall of installed solar battery, the total installed capacity of more than four. 68 megawatts, as the current domestic and Asia's largest photovoltaic building integrated grid generation system, is the Beijing Olympic Games are 7. 5 times. According to the calculation, the expo site photovoltaic building integrated system average annual capacity of 4. 08 million KWH, 3330 tons of carbon dioxide. In addition, the integration of design and construction of solar power systems than single construction cost savings of more than 30%. In terms of wind power, wind power generating capacity of the Shanghai world expo is 2 times of wind power for the Beijing Olympic Games.

the reporter understands from state grid corporation, although the expo green lights, but the actual power consumption is not too big, this is largely due to the semiconductor lighting ( 领导) The application of technology. The expo site in the urban best practices area, 'one axis and four pavilions' are all made of LED landscape lighting, more than 80% of the entire park night view lighting using LED, as the world's largest LED demonstration area.

green technology demonstrations

during the Shanghai world expo, the expo site and the surrounding mass demonstration run a total of 1080 new energy cars. After the official opening, expo site traffic will truly achieve 'zero emissions', besides adopting line on the 120 pure electric vehicles, the expo avenue line on the 36 ultracapacitors car, sightseeing car is in the park are all made of new type of fuel cell vehicles. This is currently the largest in the world's new energy automobile demonstration of commercial operation. Ecological energy-saving building, river water source heat collection and other new technology will be widely used in the expo grounds.

during the expo, the expo site will also show multiple comprehensive demonstration and smart grid demonstration projects. Electricity information acquisition system, for example, the expo park all measurement points included in the model object, the construction of electricity information collection system, the electric power enterprise can complete automatic electric energy metering, automatic meter reading, to obtain timely, accurate and complete data support, at the same time, through the project to build almost 70 monitoring stations in the expo park, the building covers 110 kv and the expo site, 35 kv substation of power quality monitoring network for effective monitoring of power quality the expo site, the state grid corporation enterprise pavilion in the expo site intelligent power building construction, through the development of integrated energy management system, real-time collecting electricity equipment running status, two-way interactive technology was adopted to realize building energy conservation and comprehensive control.

positive energy companies both at home and abroad service

the world expo not only encourages the application of innovative technology, also include and storage on the bidding mechanism, has a new idea. At the expo site, many big win by private companies and foreign companies, the project construction, the people outside, the joint venture together, have a better. For example, theme pavilion and pavilion of solar pv projects all by wuxi suntech power company specific implementation, the expo center of photovoltaic (pv) is the space mechanical and electrical company is responsible for the completion of this project. In particular, the theme pavilion, the museum has a total area of more than 60000 square meters, the installation of pv systems with a total area of 30000 square meters, is currently the world's single largest solar roof.

it is reported that more than 150000 light up every venues and LED street lamp expo park is provided by Siemens group, osram, including the China pavilion and the expo center. According to the head to our reporter revealed that GE, chevron, edf group, mitsubishi heavy industries, and other well-known foreign green technology manufacturers are heavily involved in the construction of the venues.

although construction must be diversified, with independent intellectual property rights of energy-saving technology in China in the expo is still strong. Designed and built in China with full independent intellectual property rights standard venues theme pavilions, for example, its solar roof and ecological green wall both in scope and efficiency of its most of the world.

energy future city planning of the expo energy innovation is embodied in the 'after the world expo Shanghai' energy planning. According to guo-qiang hao of Shanghai solar energy engineering technology research center, the expo center hall in energy saving energy at the same time can also provide a powerful support, implementation power 1 million degrees. After the expo, this part of the electricity will be used for the supply of Shanghai city. 'This number for about 2000 households a year. 'He said.

the other it is understood that as the sichuan xiangjiaba - Shanghai + 800000 v high voltage dc project, completed in June was put into new 35 billion kilowatt-hours per year for Shanghai southwest water and electricity, 26 million tons of carbon dioxide. That is to say, 'after the world expo' era, will be half of Shanghai electricity from clean energy, become the world's largest cities by using green power.
