- The first batch of CSP demonstration projects entered the harvest periodBy the end of 2018, a total of 200 megawatts of CSP demonstration projects have been completed and connected to the grid, creating the largest annual completion and operation history of China's solar thermal development. The industry expects that six first CSP demonstration projects will be completed and put into operation in 2019. At the end of 2018 and 2019, China's first batch of CSP demonstration projects entered the harvest period.In the new historical moment, the wind vane of the topic of light and heat industry has turned. On the 27th to 28th, 2018, China's CSP market situation and coping strategy summit and China's first megawatt-scale solar thermal power station operation results conference, the light and heat project was completed after acceptance and operation into a focus topic .In September 2016, the first batch of CSP demonstration projects identified by the relevant state departments finally achieved the first harvest in the third quarter of 2018. On October 10, 2018, China's first large-scale commercial light and heat demonstration power station --- China Guangdong Nuclear Power Delingha 50 MW light and heat demonstration project was completed and connected to the grid. On December 28, 2018, China's first megawatt-scale photothermal demonstration power station—the first-class energy-saving Dunhuang 100 MW molten salt tower type solar thermal power generation project was completed and connected to the grid. On December 30, 2018, Qinghai Zhongkong Solar Delingha 50MW tower molten salt energy storage thermal power station was successfully connected to the grid. So far, before the New Year's bell in 2019, a total of 200 MW of the first CSP demonstration project was completed. Undoubtedly, 2018 has become an important year for the history of China's light and heat development.The first batch of CSP demonstration projects has 20 projects with a total installed capacity of 1,349 MW. Hu Xipeng, chief editor of CSPPLAZA CSP platform, said: "As of the end of 2018, 200 MW of completed and put into operation projects, 350 MW of installed capacity is still under construction, 50 MW is terminated, and 749 MW has not yet been fully launched. Experts at the meeting believed that although the overall promotion of the first batch of solar thermal demonstration projects did not meet the expectations of the government and the industry, the demonstration role has already appeared.It is reported that in addition to the above three projects, Yumen Xinneng 50 MW molten salt tower type photothermal power generation project, CLP project Hami 50 MW molten salt tower type photothermal power generation project, CEC Qinghai Gonghe melting A total of 350 MW demonstration projects for salt 50 MW tower-type CSP project, Urad Zhongqi 100 MW heat transfer oil-tank-type CSP project, Lanzhou Dacheng Dunhuang 50 MW molten salt Fresnel-type CSP project Intensified construction is expected to be completed and put into operation in 2019.The actual situation of the demonstration project construction may be lower than the expectations for the thermal power project at that time, but we must consider the initial intention of the country to promote 20 demonstration projects. At that time, the CSP project in China has never been large-scale, one-off, The experience of multiple routes at the same time, so the word 'demonstration' is experimental, and many of the technical concepts used in the demonstration projects were rare in the world at the time. Many of them were pioneers. The list shows that the solar thermal power generation at the national level is considered in terms of innovation development and fault-tolerant development. From now on, it is a remarkable achievement for the demonstration project to build 200 MW by the end of 2018. Wang Yuxue, deputy director of the New Energy Department of the Water Resources Planning and Design Institute, said.Sun Rui, deputy director of the General Electric Power Planning and Design Institute, pointed out that through the construction of the first batch of demonstration projects, the rapid development of China's solar thermal power generation industry has been promoted, and the improvement of the entire industrial chain and the improvement of the overall technical level have been promoted. Accelerated the preparation of the planning of the CSP base in the relevant areas, laying a solid foundation for the follow-up project construction. "In 2019, it should be the year of the CSP industry. With the implementation of China's renewable energy power quota system, the demand for renewable energy in the central and eastern regions will increase greatly. It has been put into operation and construction. The West-East Power Transmission Area will build more CSP projects and replace the coal-fired units as the regulating power source for the transmission channels, which can significantly increase the proportion of renewable energy transmission. It will play an important role in realizing China's energy transformation strategy. He said further.Looking forward to 2019, the completed solar thermal project will usher in the test of actual operational effects and may affect the future development of the market; the multiple solar thermal projects under construction will continue to advance construction, and a new batch will be ushered in 2019. Commercialized solar thermal project is put into operation. In the joyful atmosphere of CSP demonstration projects, the industry topic has begun to turn to the discussion of the acceptance and operation of demonstration projects."No matter how much we have built, what is the ratio? According to the relevant requirements of the country, we should evaluate and announce the demonstration effect of the grid-connected power generation project as soon as possible. This is the basis for the next step of the industry development." Hydropower and Water Resources Planning and Design Institute Wang Yixue, deputy director of the New Energy Department, said."After the first flight of energy-saving Dunhuang 100 MW molten salt tower type photothermal power generation project is connected to the grid, there are four main tasks: one is to ensure the safe and stable operation of the power station; the second is to prepare for the completion of the completion of the work; the third is to carry out After the operation, the evaluation work; the fourth is to do experiments with the grid company in the hybrid scheduling of wind power and photovoltaic.” Hui Chao, deputy general manager of Beijing First Airlines Aiqiwei Energy Saving Technology Co., Ltd. said.“The establishment of CSP demonstration projects has two main purposes. One is to promote the development of the domestic industrial chain, and the other is to cultivate system integrators. The acceptance of demonstration projects should be considered from the two original intentions.” China Electric Power Construction Northwest Survey and Design Institute Zhou Zhi, chief engineer of the New Energy Engineering Institute, pointed out."The acceptance of the first batch of CSP demonstration projects cannot be equated with the acceptance rules of conventional power plants. It should be based on the development of the industry to develop acceptance criteria. To consider the integrity of the construction of photothermal demonstration projects, are all systems in accordance with The content of the demonstration project declaration is completed; the input of the whole system should be evaluated, that is, whether the project can be smoothly put into operation. It is not necessary for all indicators to be comprehensive, but to focus on some key indicators and issues affecting operation. Tian Zenghua, general manager of the New Energy Engineering Division of North China Electric Power Design Institute Co., Ltd. said, "The operation experience of China's commercialized solar thermal power station is insufficient. Therefore, the acceptance of the thermal power station should focus on the overall commissioning work of the power station. Commissioning is the premise of operation and debugging. The stage can find problems that may exist in the operation, and let the personnel involved in the later operation intervene in the debugging stage in advance to understand the specific operation of the project during the debugging process."Jin Jianxiang, chairman of Zhejiang Zhongkong Solar Technology Co., Ltd. said: "The important point in operation and maintenance is system optimization. When a power station is just running, it is based on the premise of ensuring equipment safety. Relatively speaking, waste is more serious, so later The optimized space is relatively large. There are more than 20 links in the operation of the molten salt tower type photothermal power station. These 20 links will affect the efficiency and power generation of power generation, and there is room for optimization in each link. If the optimization is done well, it is possible to increase the power generation by 5%~10% in the current situation."By: JUCRO Electric (Focus on Vacuum Interrupter, Vacuum circuit breaker, Vacuum contactor , Current/Voltage transformer, SF6 Circuit Breaker, Isolation Switch and Switchgear)2019.01.12
