Solar power generation no longer depends on the weather.

Solar power generation is no longer watching the day! Since the 24 -hour uninterrupted power generation has been achieved on June 18 this year, as of December 28, Xinjiang's first optical heat power generation project, the CNOOC -type molten salt and thermal power station, has reached 10 million degrees, marking that it should be the case. The period of the project's entry power generation also marks that my country has the ability to "store" solar energy and transport the generated power to the State Grid.

"After optimized operation, the project can continue to generate electricity for a long time. In strict accordance with the requirements of the optical power station operation assessment indicators, it is required to participate in the network adjustment and operation. The project construction is successfully completed. "On December 28, Zhou Zhiyong, deputy general manager of CLP Hami Solar Heat Power Generation Co., Ltd. said.

Since the 1990s, my country has begun the test of optical heat projects. The power station is one of the first 20 light heat demonstration projects approved by the country in 2016, and it is also the only one in Xinjiang. After the project is officially put into operation, the equipment can use 3980 hours each year, and the year -old can be generated by 198 million kWh.

"It can be said that the commercialization of my country's optical heat project is still in its infancy. The first batch of demonstration projects are not very ideal, and nearly half of the projects have not been constructed as scheduled. This project has achieved hard work as scheduled. At the forefront, Zhou Zhiyong said.

On May 23, in Laomaohu Town, Yiwu County, Hami City, the Hami Meltry Salt Tower -type 50 MW light heat power station invested by China Enterprise Investment Corporation opened more than 2,000 sun -fixed -day mirrors and mirrors. The score of the tower's top heat -absorbing device is extremely bright. The picture shows the panoramic view of the power station (drone shooting). Correspondent Li Hua

Solar power generation is divided into two types: photovoltaic power generation and photoelectric power generation. Photovoltaic power generation is the direct transformation of solar energy into electrical energy. The biggest shortcoming is that it cannot be stored. It cannot be generated when there is no sunlight. "Optical power generation can store solar energy in a certain medium and realize the power generation at night and cloudy. This project is to store solar energy into the melting salt, which can be generated at any time as needed." Zhang Yangfei, director of the company's engineering department, said.

On the Gobi Beach in Mao Lake Town, Yiwu County, more than 10,000 faces in the matrix are glory, and the silver is sparkling, which is spectacular. These mirrors automatically adjust the angle as the sun moves, and the sunlight focuses on the 180 -meter -high melting salt tower from different directions to the top of the 180 -meter -high melting salt tower. The white light shining in the air in the air is like a small sun.

Zhang Yangfei said that it is the Wan -Dao Golden light reflected by Dingri Mirror. The temperature flowing salt flowing circulating in the heat suction device is heated from 300 ° C to 560 ° C, and the heat exchange system will fully exchange the high temperature melt and water. High -voltage water vapor drives the turbine generator set to generate electricity.

"The implementation of the project has accumulated a lot of experience for the my country Optical and thermal Power Generation Project, which proves that it is feasible for optical and heat power generation technology in my country. This will reduce my country's excessive dependence on thermal power and make active active carbon peak carbon neutralization goals in my country Explore. "Zhou Zhiyong said.

It is reported that melting salt is a chemical substance, which is liquid at high temperature, colorless and tasteless. "Melving salt is only one of the solar energy storage media. Other energy storage media also include water, chemical batteries, heat conductive oils, etc. At present, these energy storage media in my country are demonstrated. And energy storage medium, "Zhang Yangfei said.
