xinhua news agency, urumqi, september 13 (reporter guo yan) looking down from the sky, there is a glittering "blue ocean" in the yili river valley that attracts attention. lower the altitude and take a closer look at this "blue ocean", which is an astonishing number of blue photovoltaic panels embedded on the grassland. along the long photovoltaic panels, li xulong is carefully checking the operating status of each device to ensure the stable output of electricity.
li xulong, 27 years old this year, works as a power quality manager at the photovoltaic collection station of the nileke 4 million kilowatt wind power and photovoltaic integration project. he is mainly engaged in power quality testing, monitoring, evaluation, and daily equipment inspection and maintenance.

the 4 million kilowatt wind power photovoltaic integration project in nileke county of xinjiang yili zhongludian new energy co., ltd. is the largest single wind power photovoltaic integration project in asia. relying on the abundant local solar energy resources, after the project is fully completed and put into operation, it can provide 8 billion kilowatt-hours of clean electricity each year, save 2.2943 million tons of raw coal, and reduce carbon dioxide emissions by 6.266 million tons.

"a photovoltaic power station is like a huge energy factory that continuously produces clean electricity. we, the power quality managers, are like the 'quality inspectors' of this factory. our task is to ensure that the electricity sent out from the photovoltaic power generation system is of high quality." li xulong described his job in this way.
the power transmission and transformation network of the power system has strict standards and requirements for power quality during operation. the voltage, frequency, power factor, power, etc. must meet the transmission requirements of the power grid. if the power quality indicators are unqualified during the operation of the power grid, the power grid system will fail to trip at best, or even collapse.
in the monitoring room of the kukbai photovoltaic collection station of china green power, facing the numbers and curves jumping on the computer screen, li xulong told reporters that by analyzing these data, it is possible to timely understand the power quality and operating conditions, discover potential problems, and take corresponding measures to resolve them.
a new career always brings new surprises. as a power quality manager, li xulong has only one year of work experience, but he is full of confidence and expectations for the new energy industry.

"it can generate electricity without interrupting the sheep herding!" li xulong told reporters that the new development model of "grazing and photovoltaic complementarity" has made him see the power of science and technology with his own eyes. he has lived in yili since he was a child and told reporters that this place used to be a barren mountain. with the completion of the project, the continuous photovoltaic panels are like huge parasols, effectively reducing the surface temperature and evaporation, reducing wind and sand erosion, and promoting the recovery of grassland.
the herders who were worried that the project construction would make the already barren land even worse also received an unexpected surprise. begersiz jiang'ersheng would shake hands and greet li xulong cordially when he saw him inspecting under the photovoltaic panels. the lush grass growing under the photovoltaic panels and the fat sheep twisting their plump bodies to walk between the photovoltaic panels made him smile.
li xulong said that in the summer, he witnessed the scorching sun on the photovoltaic panels being transformed into clean energy and continuously output, and the grasslands under the photovoltaic panels were revitalized and became food for cattle and sheep. in the winter of this year, when the grasslands turned into snowfields, there will be another wonder here. the light will be reflected by the snow and shine on the back of the double-sided monocrystalline silicon photovoltaic panels, which can also generate electricity, thus realizing double-sided power generation and increasing power generation.
"these photovoltaic panels are like flowers on the grassland. they need careful care to bloom with the most beautiful light." li xulong said that he is willing to protect these pieces of "light" and "wind" in the beautiful xinjiang, be a "light shepherd" on the grassland, and contribute his own strength to the goal of achieving green development.
