In the early morning of the fourth day of the new year, Liu Baorui received *** from his wife Liu Qianling, the first Spring Festival after the "post-95" couple got married, and they had their own Chinese New Year's Eve dinner at a substation hundreds of miles apart.
You didn't reply to the message last night, so I wanted to call you. I'm sorry wife, I was troubleshooting at the time. In the sixth minute of the call, Liu Baorui was busy going outdoors to inspect the equipment, "Wife, I will make you a big meal when I get home from duty." ”
Liu Baorui is the head of the operation and maintenance team of the Henan converter substation of the State Grid Henan DC Center. In the six years since he joined the work, it is the fifth time that he has had a Chinese New Year's Eve dinner on the front line of power protection.

Liu Baorui's South Henan converter substation is the receiving converter station of the plus or minus 800 kV UHVDC transmission project from Qinghai to Henan, which supports a "high-speed road" for Qinghai's new energy to enter Henan. Since it was officially put into operation on December 30, 2020, to February 13 this year, Henan Station has been operating safely and stably for 1,140 days, with a total of about 51 billion kWh of "green electricity". During peak hours, it can provide one-tenth of the electricity transmission in Henan Province.

In 2020, Henan Station is in the acceptance stage of the new station, and the workload is relatively large. We had just known each other, and sometimes we didn't see each other for two or three months. As grassroots power workers, it has become the norm for Liu Baorui and Liu Qianling to greet and care for each other.
He was in Zhumadian, I was in Zhengzhou, and we were both on duty this Spring Festival. Before getting married, Liu Qianling expected all this, "It's all about the power system, and we can understand each other better." ”

As the largest power grid hub in southern Henan, there are many types of equipment in Henan station and complex operation modes, and any inconspicuous hidden dangers may cause serious consequences.
"If the tower of the converter valve in the station leaks, it may cause the thyristor in the converter valve to fail, and may even lead to DC lockout," Liu said. It not only causes power loss, but also directly threatens the normal electricity consumption of tens of millions of users in Henan and even central China. Eliminating potential hazards in every piece of equipment is so important that we have to make repeated rounds more than once a day. ”
This year's Spring Festival holiday lasted for 8 days, which also brought more pressure to power supply. During the Spring Festival, the maximum DC transmission power of Henan Station reached 3,135 megawatts, and there were more than 20 power rises and falls per day. "During the Spring Festival, it takes a lot of people to ensure that people can use green, safe and stable electricity, and my daughter-in-law and I can be on duty at the same time, which feels quite honorable. ”
When Liu Baorui inspected the operation of the converter valve at Henan Station, Liu Qianling was inspecting the operation of the main transformer, combined electrical appliances and other equipment at the Xishakou substation in Zhengzhou. The Niu Yan operation and maintenance team of the substation operation and maintenance center of the State Grid Zhengzhou Power Supply Company, where she works, is responsible for the operation and maintenance of 18 substations in the western part of Zhengzhou. During the Spring Festival, Liu Qianling and her colleagues increased the number of equipment patrols to avoid the occurrence of floating objects hanging in the air on power equipment and causing short circuits and tripping of lines. At the same time, special inspections were carried out on power supply lines of important loads such as radio and television stations and New Year lantern exhibitions.

When I was patrolling outside, I heard firecrackers on the street, and when I saw the scene of a family coming out to play, I also felt a little regretful that I couldn't celebrate the New Year with my family. Liu Qianling said.
According to the Spring Festival custom, the second day of the Lunar New Year is the day of "going to the mother's house". Liu Qianling, who finished her first year of junior high school, returned to her mother's home in Ruzhou, Henan Province with the New Year's goods prepared in advance. The new son-in-law is not there, and Liu Qianling's parents are naturally a little lost. "I explained to them that during the Spring Festival, someone always has to sacrifice the time to reunite with their families, and we can't let others go home because we just got married. ”
Liu Baorui, who is accustomed to "greeting the New Year from afar" to his elders, also wants to accompany his wife back to her parents' home. "I couldn't accompany my daughter-in-law in the first year of marriage, and I feel sorry for her. ”
There are many 'grid couples' like Baorui and Qianling in the power system. It is everyone's professionalism and hard work that have brought about the safe and stable operation of the power grid and ensured that thousands of households have a warm and bright Spring Festival night. Jin Hailu, Secretary of the Party Branch of the Henan DC Center of the State Grid Henan DC Center, said Jinhailu. (Reporter Liu Zhenkun).
