China’s first large-scale energy storage power stations put into operation successfully – Beijing, China News Agency, Hangzhou, August 26 (Zhao Yejiao Mei Fangyan) 26, a good news from Qinghai Delingha returns to Zhejiang and Hangzhou, the control of Delingha 10MW solar tower thermal power station of molten salt storage light in Qinghai successfully put into operation, a large-scale storage Chinese first the successful operation of the optical power station, is the world’s third tower solar thermal power plant put into operation with large-scale energy storage. The power station uses Zhejiang central control solar technology Co., Ltd. independent research and development and independent intellectual property rights of the core technology, equipment localization rate of over 95%. The 10MW tower of molten salt storage power stations mainly through the working principle of double tank structure, with two yuan of nitrate as the heat absorption and heat storage medium, using the large-scale heliostat field collection of solar energy, the molten salt heating and storage according to the grid dispatching instructions, using high temperature and high pressure steam molten salt and water after heat exchange the driving turbine generator, realized the power output, continuous and stable scheduling. The measured temperature of molten salt at the outlet of molten salt heat receiver is up to 568 degrees. The superheated steam parameter of molten salt heat exchanger outlet is 510 9MPa, and the technical indexes reach the design value. It is reported that the 10MW tower of molten salt storage core power stations is thermal power generation technology, including light, heat, energy storage and power generation system of the core technology, because of its high power output characteristics, is widely considered one of the most likely alternative power and clean energy, has become an important direction of global new energy development. According to the International Energy Agency, by 2050, thermal power generation will meet 11.3% of the world’s electricity demand. However, the molten salt energy storage system in clean energy has been regarded as a technical difficulty by the industry, which has only been mastered by individual companies in the United States, Spain and other countries. Since 2010, in the control of solar company in Chinese national high technology research and development program under the support of science and technology, after six years, the cumulative investment of nearly 500 million yuan, has overcome the core process of technical problems, the formation of hundreds of patents and software products and other intellectual property rights. It is reported that the development of thermal power generation is an important way to promote the reform of the energy supply side and achieve a high proportion of renewable energy sources. During 13th Five-Year, China development goals will be built or installed the 10GW thermal power generation, the first batch of solar thermal power generation demonstration projects driven by Chinese National Energy Bureau will also start. The successful operation of the molten salt storage system, marking the whole process of molten salt storage China self-developed tower solar thermal power generation technology and equipment, through large-scale engineering application, with large-scale application conditions, for the upcoming launch of the demonstration projects cleared the obstacle, or will effectively promote the popularization and application of solar thermal power generation China, promote Chinese achieve energy revolution and energy transformation.
