No deserto vasto e ilimitado, os painéis fotovoltaicos perfeitamente dispostos brilham intensamente à luz do sol, como um oceano azul .} Essas usinas fotovoltaicas aparentemente simples são na verdade a cristalização de inteligência e tecnologia humana, alterando o padrão de suprimento de energia de uma maneira única e iluminando as luzes de milhares de famílias.
On the vast Gobi Desert, large photovoltaic power stations have sprung up one after another. Taking the million kilowatt photovoltaic power station in Dunhuang, Gansu Province as an example, it covers an area equivalent to the size of 1500 standard football fields, with nearly a million photovoltaic panels laid out in an orderly manner in the desert. During the day, Inúmeros painéis fotovoltaicos são como "apanhadores de sol" diligentes, absorvendo com avidamente todos os raios de luz solar e convertendo -o em energia elétrica . cada painel fotovoltaico é como uma pequena fábrica de energia, convertendo a energia dos fótons no movimento de direção (a corrente fotoelétrica « photovoltaic panel can generate over half an kilowatt hour of electricity. These currents converge and are converted by inverters from direct current to alternating current that meets the requirements of the power grid. They then pass through hundreds of kilometers of ± 800 kilovolt high-voltage transmission lines, crossing mountains and rivers, and finally reaching eastern coastal cities, providing electricity for Milhões de famílias em Xangai, Zhejiang e outros lugares para a vida diária e a produção .
The construction of photovoltaic power plants is not an easy task. From the beginning of site selection, it is necessary to comprehensively consider various factors such as lighting resources, land conditions, and grid access. A professional site selection team will use NASA satellite data to analyze the radiation levels over the past decade and select areas with annual sunshine hours exceeding 3000 hours. Land conditions are equally crucial, not only requiring flat and open terrain, but also avoiding sensitive areas such as ecological protection zones and water sources. Taking Talatan in Qinghai Province as an example, it has a high altitude, sufficient sunlight, and vast unused desert land, making it an excellent choice for building photovoltaic power stations. After determining the site selection, a large amount of machinery and A mão -de -obra é necessária para o trabalho preliminar de nivelamento do local . bulldozers, rolos e outros equipamentos rugidos dia e noite, nivelando e compactando as dunas de areia onduladas, a instalação da base é usada, a instalação de uma base é usada, que é usada, a instalação é usada para o sujeira, que é usado para a instalação de um bastão, é possível que o sujeira seja colocado, o sujeira é colocado, o sujeira é colocado, o sujeira é colocado em conjunto com o sujeira. precisely to the millimeter level to ensure that the photovoltaic panel can obtain the best light in different seasons. The laying process of photovoltaic panels is even more precise, with each panel firmly connected to a bracket through bolts, while ensuring that the gap error between panels does not exceed 2 millimeters to avoid affecting the overall power generation efficiency. During the construction process, workers have to Superar ambientes naturais severos . No verão, as temperaturas podem atingir mais de 40 graus e as temperaturas da superfície podem até exceder 70 graus . A areia sob seus pés é tão quente que é difícil de suportar; No inverno, o vento frio é arrepiante, com ventos fortes carregando areia e poeira, e a visibilidade é inferior a 5 metros ., no entanto, é o trabalho duro deles que permite que esses "oceanos azuis" brilhem no deserto .
Operation and maintenance are equally crucial. In order to ensure the efficient operation of photovoltaic power plants, staff need to regularly clean the photovoltaic panels, as dust and dirt can affect the absorption of sunlight by the panels and reduce power generation efficiency. At the photovoltaic power station in Hami, Xinjiang, after the spring sandstorm season every year, the operation and maintenance team carries out large-scale cleaning operations. In traditional manual cleaning, workers need to carry cleaning equipment weighing tens of pounds, step on specialized anti slip shoes, and carefully move between photovoltaic panels, wiping them one by one. Each person can only clean a maximum of 300-500 photovoltaic panels per day. Nowadays, intelligent cleaning robots are gradually becoming popular. They can automatically walk along the photovoltaic panels and complete the cleaning work of more than 1000 photovoltaic panels per hour by rotating brushes and high-pressure water spray devices, improving efficiency several times. In addition to cleaning, equipment monitoring has also been upgraded from manual inspections in the past to intelligent monitoring systems. In the central control room of the power station, a huge electronic screen displays real-time data such as voltage, current, temperature, etc. of each photovoltaic panel. Once a parameter is abnormal, the system will immediately issue an alarm. By using drones for inspection, large areas of photovoltaic cells can be quickly Digitalizada . equipada com câmeras de alta definição e imagens térmicas infravermelhas, ele pode identificar com precisão painéis fotovoltaicos com temperaturas anormais e circuitos mal conectados e detectar prontamente problemas em potencial; By utilizing big data analysis, combined with historical power generation data, meteorological data, etc., equipment failures can be predicted and maintenance can be carried out in advance, greatly reducing operation and maintenance costs and improving power generation efficiency. According to statistics, after adopting intelligent operation and maintenance technology, the average fault repair time of photovoltaic power plants has been shortened by 70%, e a eficiência da geração de energia foi melhorada em 8% -10% .
Essas estações de energia fotovoltaica que aumentam no deserto não apenas nos fornecem eletricidade limpa, mas também mudam o ambiente ecológico local em certa medida . a instalação de painéis fotovoltaicos reduz a água e a estação de popa de que a estação de poweats the Kubuques, que se trata de um plovóstia, o crescimento de pessoas que se refere a um plovador de vegeta as Salix and Haloxylon ammodendron, and raise livestock such as sheep and camels under the grid, gradually forming a three-dimensional ecological model of "grid power generation, inter grid planting, and grid farming". On the board, photovoltaic power stations can generate hundreds of millions of kilowatt hours of electricity annually, reducing carbon dioxide emissions by hundreds de milhares de toneladas; A vegetação plantada entre as tábuas solidifica efetivamente a areia, e a taxa de cobertura da vegetação aumentou de menos de 5% no passado para mais de 20%; Sob o conselho, o gado elevado traz renda adicional para os pastores locais, alcançando uma situação de benefícios econômicos e ecológicos para ganhar .
In the future, with breakthroughs in new photovoltaic technologies such as perovskite cells, the photoelectric conversion efficiency of photovoltaic panels is expected to increase from around 23% to over 35%, and the power generation capacity of photovoltaic power plants will be significantly enhanced. At the same time, the development of energy storage technology will also solve the intermittent problem of photovoltaic power generation, allowing Esses "oceanos azuis" no deserto para fornecer energia limpa para a humanidade de forma mais de maneira estável e sustentável, desempenham um papel maior no campo energético e se tornam uma força importante na promoção do desenvolvimento verde .
