"It is necessary to pay attention to the secondary current change of this current transformer, now the temperature is getting lower and lower, the data has a downward trend, and we should be careful of the protection malfunction caused by the failure of the optical fiber. "On Chinese New Year's Eve, in the main control room of the Yanmenguan converter station in Shanxi, a duty officer said to a colleague while checking the background parameters of the equipment on the computer.
She is Yuan Shuyuan, the only female technician in the DC maintenance class of the ±800 kV Yanmenguan converter station of State Grid Shanxi Ultra High Voltage Substation Company. Although she has only been in the company for a year and a half, under the leadership of the master, she is already very familiar with the profession. As long as she has time, she will sit in front of the computer to study the program, read the drawings and signal meters, and often take her colleagues to the site to analyze whether the operation is normal in combination with the equipment.

"This is my first time in the substation for the New Year, and the duty to protect the power makes me feel that my perseverance is very valuable, and my heart is warm. As a new force in the converter station, Yuan Shuyuan is full of curiosity and enthusiasm for everything in the station.
Another attendant who sticks to her post with her is Zhang Zhonghua, a technician in the operation and maintenance class, who has been the backbone of the converter station for nine years.
Zhang Zhonghua's family is in Pingyao, Jinzhong, and every time he goes to work, he has to cross four cities to reach the converter station. On the eve of the Spring Festival, he accompanied his wife and children to buy New Year's goods, and returned to his post on time after settling down at home.
"It is during the Spring Festival supply period, the temperature is still very low recently, and after checking the background data, let's take the leak detector and go to the scene to check the gas chamber situation. He and Yuan Shuyuan put on scarves and gloves, wrapped themselves in thick cotton clothes, and walked into the equipment area with flashlights and instruments to conduct special inspections of the equipment. The two of them went along the equipment area and checked all the air chambers one by one, and when they returned to the main control room, their hands and feet were frozen.

For the operation and maintenance personnel of Yanmenguan converter station, it has long become a habit to carry out patrol operations in extremely cold weather. "Thinking of our hard work is meaningful, to be able to protect the lights of the Spring Festival of thousands of households, it is worth it to suffer from this bit of freezing. Zhang Zhonghua said, "Not being able to go home for the Spring Festival is nothing new for us." The importance of the Spring Festival power protection work can be imagined, from on-site inspection, inspection data to background analysis and comparison, etc., every step can not be a little lax. ”
After the work, all the stationed personnel of Yanmenguan converter station came to the conference room of the main control building to watch the Spring Festival Gala. Zhao Yuting, deputy station director, said: "Although the outdoor temperature has dropped a lot today, everyone gathers here to watch the Spring Festival Gala, and the heart is very down-to-earth and warm." ”

As an important part of the "West-to-East Power Transmission" energy strategy, the Yanmenguan converter station has always maintained safe and efficient operation, and the power transmission has reached new highs, reaching 46.75 billion kWh in 2023, a year-on-year increase of 26%.
The Yanmenguan converter station continues to transport the abundant thermal power and wind power resources from northern Shanxi to East China, greatly improving the level of new energy consumption of Shanxi power grid, and effectively alleviating the tight power supply and demand situation in East China during peak hours, which is of great significance for promoting the development of Shanxi energy base and energy delivery, expanding the scope of new energy consumption, accelerating the transformation of energy revolution, and alleviating the pressure of environmental protection, and providing a stable energy supply for the realization of the "double carbon" goal.
