Perseverance is the most special "New Year's flavor". In this Spring Festival, on the occasion of family reunion, there is such a group of people, they are fighting on the front line of energy supply, giving up their small family for everyone, sticking to the motherland, writing the feelings of the family and the country with responsibility, guarding the lights of thousands of homes, and warming you, me and him.
The Spring Festival energy supply guarantee has "it" a force
The "intelligent monitoring system" accurately locks the abnormal data parameters, and the big data optimization method guides employees to accurately adjust the unit, and the "lightning sentinel" intelligent inspection robot assists in inspection...... During the Spring Festival, walking into the National Energy Group Jingran Thermal Power Company located in the Northeast Thermal Power Center of Beijing, the reporter found that a series of intelligent equipment plays an important role in the energy supply guarantee of the Spring Festival.

It is understood that Jingran Thermal Power Co., Ltd. is operating a set of "two-to-one" steam-gas combined cycle units, which can provide electricity and heat energy at the same time, with a total installed capacity of 950,000 kilowatts and a heating area of 13 million square meters.
"In order to ensure Beijing's energy supply during the Spring Festival, we have set up a special class for ensuring supply, formulated 9 power protection targets, 10 safeguard measures, and decomposed 70 tasks. Zhang Ming, deputy director of the main control room of Jingran Thermal Power Company, said that the use of intelligent equipment such as "equipment intelligent analysis platform", "intelligent monitoring system" and "passive monitoring system" to carry out 24-hour uninterrupted all-round "scanning" of the equipment of the whole plant to ensure the safe and stable operation of the unit.
"This is the APS unit one-button start, you come and try it. In the simulation room, Wang Jiadong, the director of the main control room of Jingran Thermal Power Company, handed the mouse to the reporter. With a single click, the unit quickly realized the boiler water supply, gas turbine start-up and grid-connected operation.
According to Wang Jiadong, the one-button start realizes the safe, reliable and fast start of the unit, responds to the load changes of the power grid in a timely manner, flexibly switches the operation mode, and at the same time meets the demand of the Beijing heating network for thermal load and ensures the stable supply of electricity heat in Beijing. It also realizes the automatic fault recovery of the unit, ensures the safety of the equipment in the external network failure state, and adds double insurance.

When I came to the production plant, the reporter saw that the "Lightning Sentinel" intelligent inspection robot was inspecting. The safety of the generator set is guarded by means of equipment scanning in the inspection area, equipment screen return in the inspection area, automatic collaborative statistical processing of data, and abnormal alarm of equipment.
"The 'Lightning Sentinel' intelligent inspection robot can carry out high-quality inspections 24 hours a day, allowing us to devote our energy to the analysis and precise adjustment of unit parameters, which not only saves manpower but also ensures safety. Shen Junheng, a duty officer in the main control room of Jingran Thermal Power Company, said, "Although I can't go back to my hometown in Yunnan to accompany my parents for the Spring Festival, I feel that my perseverance is meaningful when I look at the lights that are lit up at night." ”
During the Spring Festival, I was busy mining coal in the north
During the Spring Festival, 77 wide-body dump trucks were produced at full capacity in the Zaharnaoer open-pit coal mine of the Inner Mongolia Company of the State Power Investment Corporation, and all aspects of coal mining, packaging, transportation and sales were efficiently organized, and nearly 50,000 tons of fine and high calorific value coal were supplied to all parts of the country every day.

Zhao Tiezhu's wide-body dump truck loaded with "Wujin" came from the coal mining and loading site to the coal crushing station three kilometers away, reversing, lifting and unloading...... With a rumbling sound, in just 3 minutes, 50 tons of coal poured down and entered the "steel giant" material silo that can crush 1,850 tons of coal per hour.
Crushing efficiency directly affects energy supply, and it is very important to ensure the efficient operation of the belt. "Now the task of coal production is heavy, the maintenance time of the coal conveying belt has been changed from 6 hours to 4 hours, and the extrusion is 2 hours for production. During the Spring Festival, Mao Ruibing took the initiative to give up the opportunity to reunite with his family, "Coal supply is guaranteed, it can be produced, and it must be transported." During the Spring Festival, our team was responsible for sending out coal to ensure central heating in four medium-sized cities in Northeast China, and we were very happy. ”
Not far away, in the intelligent control center, Yang Jimin sat in the intelligent operation room and observed the operation of the coal conveying belt through the remote monitoring system.
Every day, 50,000 tons of coal are transported to the northeast region to ensure the heating supply of four medium-sized cities. Photo courtesy of the interviewee
"The automatic correction of the coal transport special train was completed, and the intelligent quantitative loading system was started. Yang Jimin pressed the start button, and the loading chute, tape machine, and transfer machine on the screen started in turn, and the memory loading began according to the instructions entered in advance. A special train carrying 7,616 tons of coal was loaded in 115 minutes and transported to all parts of the country.
As night falls, the lights come on. Yang Jimin, who had been busy all day, sent a video call to his parents and wife, looking at the happy smiles of his parents, the pictures of his children laughing and playing, and listening to his wife pulling a homely ......, "The Spring Festival is a day of family reunion, although I can't be with my family, but when I think of my work, I am very happy with the warmth of thousands of families." Yang Jimin said.
The persistence of the very high ground
In winter on the Tibetan Plateau, the lakes are frozen. In addition to the cold, this is also the time of year when the oxygen content of the air is lowest.
Approaching the Spring Festival, the operation and maintenance staff of the Three Gorges Group's Cuomei Zhegu Wind Farm in Tibet are stepping up inspections. They had to complete the overhaul of the 15 newly connected wind turbines before the Spring Festival to ensure the safe and stable operation of the wind turbines during the Spring Festival.
Tsering Sangzhu, a Tibetan boy, took his first job after graduation and became an engineer at the world's highest altitude wind farm. "Our turbines are located at an altitude of 5,000 to 5,200 meters above sea level, and the oxygen content is almost half that of the plains. Tsering Sangzhu said.

The high cold and low pressure hypoxia not only brings challenges to the body, but also adds difficulty to their work. Li Wei, an engineer at the Cuomei Zhegu Wind Power Construction Project Department, said: "The same work of tightening bolts in the engine room can be done in half a day in the plains, but it takes a day to a day and a half to complete when you get here." Winter is the windy season on the Zhegu grassland, and our operation window is even shorter, so we must seize the morning when the wind is light to carry out high-altitude work, and often have to set off before dawn to prepare. ”
Tsering Sangzhu told reporters that the experience of power outages when he was a child made him feel that his work was very meaningful. Every inspection, every tightened bolt will not be in vain, because one kilowatt-hour of electricity may light up a long night of anticipation.
"Plateau, high anti, high altitude", Zhang Haozhe often laughs at himself as a "new three-high patient". "In the area of our wind farm, it is easy to see Tibetan wild asses and Tibetan antelopes, and whenever we see that they are so harmonious with the wind turbines on the ridge in one picture, I feel that we are turning the wind here into clean electricity, promoting development and protecting the ecology, which is very worthwhile. Zhang Haozhe said.
At this moment, the "big windmills" at the foot of the snow-capped mountains are continuously delivering clean electricity to Shannan City, Tibet, warming every family in the cold winter.
A different kind of New Year's flavor of the deep Taco 1 well
On Chinese New Year's Eve, February 9, the drilling rig rumbled at the well site of the mainland's first 10,000-meter exploration well in the hinterland of the Taklamakan Desert, and the vertical drilling depth has exceeded 9,850 meters, and it is advancing to a depth of 10,000 meters day and night. More than 150 staff members gave up their vacations and stuck to their posts to make the final sprint to break through 10,000 meters.
At the well site at night, although everyone is fully armed with cotton wool and jackets, the temperature at night exceeds minus 10 degrees Celsius, and the cold still drills into the cracks of the bones.

On the 15-meter-high drilling platform, Nan Haisheng, the driller of the 120001 drilling team of PetroChina Western Drilling Bazhou Branch, held the brake lever in his hand, stared at the complicated data on the dashboard, and controlled the ups and downs of the drill bit. "I just finished my Chinese New Year's Eve dinner at the camp, and now it's my turn to work. For us, drilling safely and smoothly to 10,000 meters is the 'New Year'. Nanhai Sheng said.
In the well site laboratory, Wang Xiaoming of the Geological Experiment Center of the Tarim Oilfield Experimental Testing Institute rubbed his frozen and numb hands and carefully examined the cuttings taken out from more than 9,000 meters underground.
"There are almost 100 wells here, and sometimes even if there are two adjacent wells, there will be different lithologic combination characteristics, and we must find the clues of accurate geological information from the cuttings to guide the next drilling technical countermeasures. Wang Xiaoming said.
The bell rang at midnight, outside the camp of the well team, firecrackers rang out, brilliant fireworks lit up the entire night sky, and the employees felt a different flavor of the New Year in the sea of sand.
"Everyone came here from all over the world to build this well, play a 'big country depth', and practice the promise of 'I dedicate oil to the motherland' with actions. Wang Chunsheng, chief technical expert of Tarim Oilfield and director of Deep Taco 1 well, said.
