Energy technology to light the "low-carbon Expo" a variety of energy-saving technology booth

In May 1st 2010, Shanghai World Expo officially opened to welcome Chinese and foreign tourists from around the world, 189 countries and 57 international organizations, the actual exhibition, created in World Expo in 159 years of the history of the most. The theme of this World Expo is "Better City, better life", "green, low carbon, sustainable" and other environmental elements in the big stage in World Expo has been fully reflected.

"Wind" "light" unlimited welcome Expo

Look at Expo Park, green technology can be seen everywhere, and the biggest bright spot is the large-scale application of solar energy, wind energy. The park museum, China Pavilion, Expo Center, performing arts center and other major facilities as well as self built museum in many countries, in the form of the roof and curtain wall installation of the solar battery, the total installed capacity of more than 4.68 MW, as the current domestic and Asia's largest Guang Fujian built the integration of grid connected power system, is 7.5 times the Beijing Olympic Games the amount of. According to the calculation, the annual average power generation capacity of the Expo Park photovoltaic system is 4 million 80 thousand kwh, carbon dioxide emissions can be reduced by 3330 tons. In addition, the integration of the design and construction of solar power generation system than the cost savings of more than 30%. In wind power, wind power in Shanghai, World Expo is 2 times the amount of wind power in Beijing.

Reporters learned from the national Power Grid Corp, although the Expo bright lights, but the actual power consumption is not too large, which is largely due to the application of semiconductor lighting (LED) technology. The best practices in the Expo area, "one axis and four Pavilions" landscape lighting all use LED, the park more than 80% of the night lighting using LED, becoming the world's largest LED demonstration area.

Green technology demonstration

Shanghai, World Expo, the Expo site and a total of 1080 new energy vehicles around the large-scale demonstration operation. After the official opening of the Expo site traffic will truly achieve "zero emissions", in addition to the river line on the 120 pure electric vehicles, the Expo Avenue line launch 36 super capacitor car, sightseeing car park are all using a new type of fuel cell vehicle. This is also the world's largest commercial demonstration of new energy vehicles. Ecological energy-saving building, river water source heat collection and other new technologies will also be widely used in the Expo garden.

During the Expo, the Expo will also demonstrate a number of smart grid demonstration and demonstration projects in World Expo. For example, electricity information collection system, all the measurement points within the Expo site included in the demonstration object, electricity information collection system construction, electric power enterprises can complete automatic power metering, automatic meter reading, timely, accurate and complete data, at the same time the project through about 70 new monitoring points within the Expo site, the construction of the Expo site covering 110 thousand volts and 35 thousand volts transformer substation power quality monitoring network, the Expo power quality effectively carry out electricity monitoring, intelligent building construction in the Expo national Power Grid Corp enterprise Museum, through the development of energy management system, real-time operation state of electric equipment, realize the comprehensive control of building energy saving using two-way interaction technology.

Domestic and foreign energy companies active service

The Expo will not only encourage the application of innovative technologies, but also on the bidding mechanism and storage, quite innovative. At the Expo site, many large won by the private enterprises and foreign enterprises, in the construction of the project, people outside the country, and foreign forces, good results. For example, the theme pavilion and the Chinese Pavilion solar photovoltaic projects are implemented by the Wuxi Suntech solar power company, the Expo Center photovoltaic project is completed by the aerospace mechanical and electrical company. It is particularly worth mentioning is the theme of the pavilion, the total area of 6 square meters, the installation of photovoltaic systems with a total area of up to 30 thousand square meters, is currently the world's largest single monomer solar roof.

It is understood that more than 150 thousand lights lit the Expo venue and the streets of the LED lights are provided by SIEMENS group's OSRAM, including the China Pavilion and Expo center. According to the relevant person in charge told reporters that the construction of GE, Chevron, the French power group, MITSUBISHI heavy industries and other well-known foreign manufacturers a lot of green technology to participate in the expo.

Despite the diversity of the main building, with independent intellectual property rights of China's energy-saving technology is still eye-catching performance in the expo. In the case of the theme pavilion, which has been designed and built by China, with independent intellectual property rights, its solar roofs and eco green walls are the world's largest in terms of scale and efficiency.

Future urban energy planning

The Expo's energy innovation is also reflected in the post Expo Shanghai energy planning. According to Hao Guoqiang, Shanghai Solar Engineering Technology Research Center, the Expo Center in the energy saving can also provide a strong energy support, the annual power generation of 1 million degrees. After the Expo, this part of the electricity will be used to supply electricity to the city of Shanghai. "This figure can be used for about 2000 households a year. He said.

It is also reported that, along with Sichuan Xiangjiaba - Shanghai + 800 thousand volts HVDC project was completed and put into operation in June, the annual increase of Shanghai will be more than 35 billion kwh of Southwest hydropower, carbon dioxide emissions by 26 million tons. In other words, after the era of Bo, half of Shanghai's electricity consumption will come from clean energy to become the world's largest cities using green power.
