With the unique climate endowment, Qinghai Province's photovoltaic and wind power such as photovoltaics and wind have achieved significant development in recent years. In February 2018, my country officially approved the construction of Qinghai to build a national clean energy demonstration province. How much is clean energy development due to meteorological conditions? What are the meteorological stories behind?

Follow the China Meteorological Daily reporter, go deep into the front line of Qinghai Clean Energy Development!

1. There are "rich mines" with light and heat energy here!

Qinghai, because of its name, is the birthplace of the Yellow River, the Yangtze River, and Lancang River, and the most concentrated areas of the largest rivers and rivers in Asia. The Qinghai region is vast, the climate is cool and pleasant, with the lowest daily and the highest temperature of only -1 ° C and 15 ° C. It is one of the world's four largest pollution-free super-net areas. The climate and geographical advantages are obvious.

Da Mei Qinghai is a beautiful green business card for beautiful China, and it is also an important strategic area for the development of the country's new energy industry. Qinghai Fuguang, Fengshui, and Wind are good. They are the "big provinces" and "rich provinces" of clean energy resources.

The reporter's visit to Qinghai China Control Delingha 50 MW Light Heat Power Station is located in Delingha, Tibetan Autonomous Prefecture, Haixi Mongolia, Qinghai. "De Lingha" is the meaning of the Mongolian "Golden World", marking Dezingha, who is on the Qinghai -Tibet Plateau, and sufficient light!

The solar radiation is high and the water resources are relatively abundant, which determines the huge potential of the light and thermal power generation here.

Entering the Delingha New Energy Industrial Park, looking at it from a distance, a piece of light and hot -fixed -day mirror arranged and extended. In the Gobi Hanhai Sea, it looks like a quiet blue ocean, opening the energy given by the sun.

According to statistics, since this year, Delingha's 50 MW omit thermal Demonstration Project has accumulated about 60 million degrees power generation. The 2 million kilowatts of light thermal storage projects are under construction, and the annual power generation is expected to reach 3.65 billion kWh.

Liu Yiding, general manager of a certain optical heat project who has worked in Delinga for many years, said: "The light heat power station is like a huge 'charging treasure'. Compared to new energy power stations such as photovoltaic and wind power, it is more suitable as a flexible base lotus. Power supply and peak -adjusting power supply to achieve continuous operation of 24 hours, which helps the power system to operate stable. "

After reading this, maybe some friends are going to ask, is the photovoltaic power station the same as the photovoltaic power station? What weather conditions are affected by the light heat power station?

2. Meteorological and wisdom to dig climate endowment!

Experts from the Qinghai Meteorological Bureau told the China Meteorological Newspaper reporter that at present, the solar power generation model mainly includes two forms: photovoltaic power generation and photoelectric power generation.

The optical power generation system uses the heat of the sun to generate electricity. Light heat power generation, also known as focusing solar heat power generation. By a large reflex mirror, solar energy is accumulated directly by focusing, heating and generating high temperature and high -voltage steam to drive the turbine to generate electricity. While power generation, the excess heat energy can be stored in the energy storage container, released at night or rainy days, and can ensure that it can be continuously stable for 24 hours.

Photovoltaic power generation uses solar panels to absorb the visible light in the solar light to form photoelectric, generate current power generation. However, this power generation method is easily affected by weather. The power output volatility is high, and it is easy to impact the power grid.

Compared with photovoltaic power generation, photovoltaic power generation has advantages in continuous power generation, energy storage capacity, energy storage cost, stability, safety, environmental protection and life span.

In actual engineering applications, in order to obtain maximum production capacity, the solar panel of the photovoltaic power station is generally fixed on the ground at a certain angle, and the power generation power is mainly affected by the total radiation of the tilt surface; (DNI, which means the radiation power of the unit area vertically in the direction of radiation), so it is necessary to track the orientation of the sun (sunlight) in real time.

The operating cost of the photovoltaic power generation system is higher than that of photovoltaic, especially in cloudy and cloudy days. The reduction of solar resources will seriously affect production capacity, so the requirements of meteorological service guarantee are higher. In order to ensure economic benefits, whether the optical power plant is turned on and runs, it is necessary to refer to the direct radiation resource volume within a certain period of time in the future.

Targeted short -term weather forecasts can also formulate the power storage tank filling and indoctivity plan for power stations to provide decision -making basis.

In response to service needs, the Qinghai Meteorological Department comprehensively considers the local special geographical location and climatic conditions, from the refined evaluation of site selection and solar resources to engineering lightning protection design. Services, provide tracking meteorological services around the entire industrial chain! The staff of the local meteorological department have repeatedly penetrated new energy companies to understand service needs and customized meteorological security services.
