Chengdu Business Daily-Red Star News, "There was no power outage without notice, and the meal was still not ready." Xiao Dong, who lives in a village in Heilongjiang, recited this sentence three times. At eight o’clock in the evening, the village was electrified again. This time, Xiao Dong turned out all the tools that can be charged, including a rechargeable flashlight from ten years ago.
In recent days, power outages have occurred in many places in Northeast China. Wu Jingping, member of the Standing Committee of Jilin Provincial Party Committee and executive vice governor, pointed out at the relevant meeting of Jilin Province on September 26th that the national coal shortage, high coal price and upside-down price of coal and electricity have led to power shortage in many provinces. Nowadays, the notice of power restriction issued in many places also indicates that the coal price is running at a high level and the power coal is in short supply. If the power shortage is not alleviated, the power restriction work may continue.
Some analysts pointed out that at present, the domestic production capacity of thermal coal and coking coal has obviously shrunk, and with the decrease of coal imports, the customs clearance of Mongolian coal is low, and the supply of electric coal is obviously short. The high coal price leads to the loss of power generation enterprises that can’t raise the electricity price, and the enthusiasm for power generation declines. The imbalance between power supply and the high demand for electricity brought about by China’s economic recovery after the epidemic is the fundamental reason for the current power restriction.
In addition, the emergency power cuts in some places are also related to not grasping the pace of industrial upgrading, not doing a good job in energy management at ordinary times, and not jumping out of the pattern of sports carbon reduction.

On September 27th, the State Grid said that it would go all out to ensure the basic people’s livelihood electricity demand, avoid power cuts as much as possible, and resolutely hold the bottom line of people’s livelihood, development and safety.
For some residents in the three northeastern provinces, facing the power outage has become the most realistic "life" at present.

Leave the mobile phone with only 12% battery.
The power of the mobile phone is only 12% after the power failure, and the steamed buns that my mother just wrapped haven’t had time to be steamed. These are the two problems that Xiao Dong is most worried about after the sudden power failure in her village.
Xiao Dong lives in a village in Heilongjiang. At 4 o’clock in the afternoon on September 24, the sky in the east has begun to get dark. Suddenly, the lights in the living room went out and the wireless network was cut off. Xiaodong realized that there was a power outage. Her first reaction was to look at her mobile phone and found that there was only 12% power. She hurriedly called her grandfather in the east of her home first and found that the whole village was out of power.
After the power failure, because there is no bottled water at home, the drinking water filtered by the water purifier can’t be drunk for the time being, and the tap water has stopped; Cooking at home also uses an induction cooker, and she looks at the induction cooker and starts to worry; Mom’s steamed buns haven’t had time to be steamed, and the side dishes can’t be fried. How to eat dinner has become a problem. In the circle of friends, several friends’ homes have also lit candles, and the lights are printed on the white wall.
↑ Some northeast residents turned out candles that had not been used for many years.
Without food, the family was "hungry and staring at each other" at home and had to go out for a walk. On the way, Xiao Dong found that the traffic lights were all out, but because there was less traffic in the village, the traffic was not chaotic. In the square, the content of everyone’s chat is nothing more than "when can the power supply be normal?" What’s going on here? How do you cook at home? What are you eating? "
Soon after, the family found a restaurant with generator power supply. There was a long queue at the door of the restaurant, and only two staff members were busy in the front hall. The restaurant is full of people, and everyone faces the same dilemma of "no electricity to cook". Some familiar villagers are talking about the power outage in a lively environment.
Xiao Dong’s family ordered scrambled eggs with tomatoes, shredded potatoes in vinegar and rice to take home, and they ate them while the food was still cold. "If you can’t do anything, just lie in bed and close your eyes." Digging out candles that have not been used for many years, Xiao Dong and his family returned to their respective houses. It wasn’t until 9 o’clock in the evening that Xiao Dong felt her eyes lit up and finally called. She got up, put the drinking water on the system and the domestic water reserve, and then charged the mobile phone that had already been turned off, but she didn’t think of charging the charging treasure.
At that time, Xiao Dong and his family didn’t realize that the power outage, which lasted for about 6 hours, was related to a large-scale power cut that affected many provinces, cities and regions.
At 9 o’clock the next morning, Xiao Dong found that there was another power outage. "I still haven’t had time to cook." Xiao Dong has been chanting it for three times.
Soon after, the village issued a notice informing the villagers that there would be no time limit for electricity in the future, but it did not say when it would last. "At the moment I saw the notice, my heart collapsed." Xiao Dong said. However, she later found on the Internet that a similar situation occurred in many areas in Northeast China: "It turns out that everyone has cut off water and electricity. It seems that I am not alone."
At eight o’clock in the evening, the village was electrified again. This time, Xiao Dong didn’t forget to charge the charging treasure. "I even found the rechargeable flashlight ten years ago and charged it." Since then, in order to cope with this situation, Xiao Dong’s home will store water every day to fully charge the mobile phone and other electrical appliances.
According to reports, according to the current situation of power supply and demand, the "orderly use of electricity" in Heilongjiang Province will continue for some time. At present, the Heilongjiang Provincial Party Committee and the provincial government have explicitly requested to fully guarantee the basic livelihood electricity demand, ensure that residents live in warm houses in winter, and actively organize maintenance and shutdown units to resume grid-connected operation, and provide coal guarantee for power generation.
Xiao Dong believes that this situation will not last long. Xiao Dong told reporters that the candle reserve at home is sufficient, and he is not worried that this situation will affect winter heating. "I believe that the country should ensure the normal life of residents."

45 minutes of a family of four trapped in an elevator
At 9 o’clock on September 26th, 2021, Ms. Jiang and Mr. Liu went out with their 1-year-old daughter and 4-year-old son as usual in Kangqiaoyiju Community, Dunhua City, Yanbian Korean Autonomous Prefecture, Jilin Province. They live on the third floor, and there is no elevator exit on the second and first floors below, so they have to leave the community on the first floor.
The episode happened after a family of four entered the elevator. Ms. Jiang and Mr. Liu are still talking about "what to eat for breakfast today". They suddenly feel an external force and the elevator suddenly gets stuck. "It feels like a brake." Mr. Liu described this.
Almost at the same time, there was a thump, and the lights in the elevator car suddenly went out, leaving only a coin-sized emergency light emitting a faint light on the top of the car.
Ms. Jiang felt extremely nervous for the first time. Is it that the elevator is out of order? She quickly asked Mr. Liu next to her: "What happened?" Mr. Liu looked very calm, and his mind quickly recalled the news about the power outage he saw these days and immediately reacted, "This should be a power outage."
= data map. Both Liaoning and Jilin said that it is necessary to avoid power cuts as much as possible.
At the same time, although the dark environment did not make the young daughter feel uncomfortable, the 4-year-old son has shown some anxiety.
"It’s okay, we’ll stay here for a while and then go out." Mr. Liu comforted his son in a relaxed tone. He tried to convey the idea that "the family is playing in the elevator" to the children and didn’t want them to think much. He turned on the flashlight on his mobile phone and handed it to his son. There was a beam of light in the elevator instantly, and the fear in his son’s heart was basically eliminated.
The two began to seriously consider how to leave. The couple’s first choice was the distress bell and emergency call in the elevator. They pressed it many times and didn’t get timely feedback. Ms. Jiang quickly thought that she could call the property, but Mr. Liu’s mobile phone had completely lost the signal. Fortunately, Ms. Jiang’s mobile phone still had a weak signal, leaving a glimmer of hope. However, she failed to dial the property manager and the property manager about three times each.
Time is slowly passing, and the closed environment begins to deepen the fear. Taking advantage of the intermittent signal, Ms. Jiang tried to call her neighbor Mr. Wang, and finally got through this time. Under the guidance of Mr. Wang, the property staff came to the scene and found that the elevator was trapped in the wall in the middle of the floor. There was no way to rescue it directly and found the elevator maintenance personnel. After the maintenance personnel entered the elevator room, they tried to shake the elevator back to the third floor by manual operation.
↑ Ms. Jiang, the situation of Mr. Liu’s family trapped in the elevator.
In the process of waiting, the two children were already a little anxious. Fortunately, they took milk powder with them and gave it to their children before their emotions eased. After another 20 minutes, the elevator finally returned to the third floor, the door was opened from the outside, and Mr. Liu breathed a sigh of relief. This accident is also the first time they have encountered power cuts. In the next two days, the electricity in the community has not stopped. As for why the property didn’t answer the phone at that time, they said that after the sudden power failure, the staff rushed to manually open the garage door and missed the call.
"The elevator is broken. Let’s take the stairs." The son told his mother that Ms. Jiang also felt a little scared. For the possible power outage after that, the property staff said that if the owner is trapped in the elevator again, the staff in the duty room can bring the key to open the elevator door directly; And if Ms. Jiang’s family is stuck in the wall, the staff will immediately find the elevator maintenance personnel to ensure that the trapped person can be rescued within 30 minutes.

Failure flash flood warning software
"In the past few days, due to the limited film of the power grid, the flash flood warning software may not be easy to use. It is hard for everyone to go to the dam for field observation."
On September 26, Mr. Wang, who worked in a reservoir in Dandong City, Liaoning Province for more than 20 years, rarely encountered such a situation. After receiving the news, he immediately informed the observers.
The main functions of local reservoirs are project management, reservoir flood control and water conservancy dispatching, and they are also engaged in aquaculture, power generation and tourism. The data of rain and water regime are mainly mastered by flash flood warning software, and the water level has not been measured by manual field observation for a long time.
Mr. Wang also heard the news of the power cut, but the electricity consumption in the dormitory was not affected. He is in the countryside, with a vast land and a sparsely populated area, and the nearby mobile base station also has a backup power supply.
= data map. At present, thermal power is still the most important source of power supply in China.
The change took place on this day. He found that when receiving the data from the telemetered water level station and the telemetered rainfall station, there was always a signal interruption, which caused the data of these two days not to be transmitted to the reservoir terminal. "Fortunately, the flood season has just passed." Mr. Wang said that as long as the water level rises, they can use the software to monitor it in real time, and mastering these two data is the key to controlling the water regime and making a basis for reservoir dispatching.
Transmission failure can only be remedied manually. In the following days, observers need to go to the reservoir hundreds of meters away at 8: 00 every morning, manually observe the fluctuation of water level and make records, and report it to the rear for statistics at the first time.
Fortunately, it hasn’t rained in the local area for a long time. The water level of the reservoir has risen slowly in the past two days, up to one or two centimeters a day. "If the water level rises rapidly in the flood season, it needs accurate data. If you can’t grasp the data at the first time, it will affect the reservoir dispatching and further affect the downstream flood control safety." Mr. Wang said.
In the notification of the power supply companies in Jilin and Tonghua, State Grid, besides the shortage of coal and the large shutdown capacity of thermal power units, it also mentioned the comprehensive influence of the small power generated by new energy sources, which led to the continuous shortage of power supply in Northeast Power Grid.
"Now there is a shortage of electric coal, and hydropower in our country accounts for a small proportion of the total, but hydropower is a green energy source, and hydropower stations should be vigorously developed in areas with abundant rainfall." Mr. Wang believes that the current electricity price can be adjusted appropriately, and the waste of energy can be avoided through price leverage, and at the same time more investment can be attracted.
