Tianjin North network news: as soon as spring comes, the five "big windmills" standing by the rainbow bridge of the ecological city turn more happily. Every spring is their most diligent day, and it is also the season with the highest power generation of this wind power project.
eco city's "first impression"
Walking slowly along the Bank of Jiyun River, the beautiful scenery along the river is waking up, and the 75 meter high "windmill" has been integrated into the urban landscape and has become people's "first impression" of the eco city.
In fact, there are not many wind power projects in cities. The wind power project of Jiyun estuary, an ecological city, is also the first concentrated scale estuarine wind farm in Tianjin. Its site selection and construction reflect the determination and courage of the eco city in the utilization of renewable energy.
"In the early stage of construction, we conducted feasibility study and analysis in combination with the meteorological records of the meteorological station, and finally determined the location by comprehensively considering the parameters such as wind speed, orientation, air flow stability and air density." Yuan Yue, director of the enterprise development department of Tianjin eco city energy investment and Construction Co., Ltd., talked about the project like a treasure. Yuan Yue said that if the windmill wants to turn, it must ensure that the wind speed on the windward side of the fan blade reaches 2-3 meters per second and lasts for several minutes. Therefore, the peak season of wind power generation is from November to May of the next year.
According to statistics, the wind power project of the eco city has generated 37.98 million kwh since it was connected to the grid in November 2011, with an average annual power generation of about 3.8 million kwh.

When it comes to renewable energy, the photovoltaic power generation project of eco city also occupies a place. In 2013, the building photovoltaic project on the top of the four public buildings in the animation Park was completed for power generation. Since then, the building photovoltaic project in the science and Technology Park, the sewage treatment plant photovoltaic project, the Central Avenue photovoltaic project and the northern high voltage zone photovoltaic project have been put into use, providing a steady stream of light energy for the eco city.
On the one hand, these electricity can be consumed locally to provide lighting, air conditioning, fire fighting and other equipment for the main body of the building; On the other hand, it is sent to the transmission network as green energy and supplied to thousands of households by power grid dispatching.
For photovoltaic power generation projects, the maintenance after completion is particularly important. In order to overcome the attenuation of power generation caused by environment, cable loss and other factors, eco city energy company not only strengthened daily inspection, maintenance and management, but also actively carried out technology R & D and upgrading in conjunction with Tianjin Shenglian Smart Technology Development Co., Ltd., so as to make the "old equipment" glow with "new vitality".
Below the high-voltage belt in the north of the eco city, a Cecep Solar Energy Co.Ltd(000591) photovoltaic power generation project with a total installed capacity of 0.37 MW is working quietly. One of the photovoltaic panels is equipped with a "photovoltaic cleaning Siasun Robot&Automation Co.Ltd(300024) ", which is a new technology independently developed by the eco city and under trial operation.
According to Chen Chuan, director of new energy in the operation management department of eco city energy company, the Siasun Robot&Automation Co.Ltd(300024) body is equipped with photovoltaic power generation panels, which can achieve self-sufficiency in energy consumption. Next to it is a miniature photovoltaic weather station, which can monitor the local irradiation intensity, heat conversion rate, photovoltaic panel dust, etc., and return the data to the background. Combined with the algorithm, it can issue instructions for cleaning Siasun Robot&Automation Co.Ltd(300024) to complete the automatic cleaning process.
At present, the integrated platform is applying for R & D patents. A UAV inspection system for roof photovoltaic projects is also under development.
building renewable energy brand
At the beginning of the construction of the eco city, the expert teams of China and Singapore jointly prepared the eco city index system and took the lead in clarifying the development objectives of the eco city with quantitative methods.
Guided by the index system, the eco city has gradually established a comprehensive renewable energy utilization system focusing on Cecep Solar Energy Co.Ltd(000591) , geothermal energy, wind energy and biomass energy. It is a leading demonstration area for China to carry out systematic and comprehensive utilization of a variety of renewable energy.
As early as 2015, the Central Avenue photovoltaic power generation project, the northern high voltage zone photovoltaic power generation project and the jiyunhekou wind power project of the eco city passed the review of the filing review meeting of the national development and Reform Commission's voluntary emission reduction project (CCER), and became the first batch of CCER projects registered by the state in Tianjin.
Not long ago, with the help of 513 tons of national certified voluntary emission reductions (CCER) cancelled by eco city investment and Development Co., Ltd., the fourth community center of eco city realized pre carbon neutralization, obtained the carbon neutralization certificate issued by Tianjin emission right exchange, and became the first "zero carbon" community commercial project in Tianjin.
In the next step, the eco city will accelerate the listing and trading of "carbon assets" according to its own carbon emission demand and relevant policies on carbon market trading. At the same time, it will continue to promote the application of low-carbon new products, new technologies and new models, strive to create a series of zero carbon demonstration scenes and projects, build renewable energy brands, and provide a model for Tianjin and the country's low-carbon development and carbon neutrality.
