Two years ago, solar power project in Qinghai Province, Haixi state is the first to achieve the industrialization of the project, the project has a power generation capacity, will soon achieve grid power. The total investment is nearly one billion yuan.At present, the first phase of the project is 10 MW investment 210000000 yuan, all the projects have been completed by the end of 2014.
The solar power project is controlled by Qinghai in the construction of solar power Co., Ltd.,thousands of mirrors are Installed on the ground, with the key technology to control the glass mirror like sunflower chasing the sun light, will be reflected to the heat absorbing tower on the heat absorber, the water into high temperature steam, and then through the pipeline to promote turbine generator. This is the core technology.
In the Qaidam Basin, it is of high altitude, rainy days, long duration, high intensity of radiation, good atmosphere and good transparency. It is suitable for the development of solar energy resources. The area of solar power generation is only suitable for the development of solar energy in Delingha. The photoelectric conversion rate of solar photovoltaic power generation is 14%~17%, and the photoelectric conversion rate of solar power project is 20%, and the thermal power generation has the advantages of stable and long time. At the same time, the use of solar power project are mainly raw materials for steel and flat glass, will not form the two pollution.
Our country is rich in solar energy and heat resources. The area of Northwest China is located in the "sun belt". It has a unique condition. Through the analysis of geographical information system (GIS), the total area of solar thermal power generation in China is about 16000 MW, and the reserves of our country are quite comparable to that of the United States. In terms of annual generating capacity, the potential of solar thermal power generation capacity of 42000000000000000 kwh, while the current annual output is about 5000000000000000 kwh of electricity in china.
At present, the five major power company holding more project resources and control and other private developers are to be eager for a fight. Some analysis, after the demonstration stage, solar power project is expected to usher in the outbreak period. According to the Chinese government had planned, by 2020 to achieve installed 3 gigawatts of solar thermal power generation is the minimum of the objective, investment per kilowatt cost down to 3 00000 yuan calculation, by 2020, China's solar thermal power generation market scale will exceed billion yuan.
