In 62, the strongest high temperature kept the load of electricity continuously rising. Where does the steady cool breeze from Wuhan's home come from?

Jimu Journalist Cao Lei

In the last week of August, Wuhan, who has experienced more than a month of high temperature and hot weather, finally ushered in a real coolness in a autumn rain.

Looking back at this month, high temperature and power supply, Wuhan's electricity is not afraid of the "baking" test, always adheres to the front line of the electric line, the electrical equipment guarantees the front line, uses the power to serve the front line, and uses its own sweat to protect the residents' families Cool.

This summer, Wuhan ushered in the strongest high temperature in 62 years. The power load of this large city has continued to rise, but Minsheng's electricity consumption has been stable. Under the high temperature of the heat, the air conditioners in the residents' homes can freely send out the cool breeze.

Where does a ray of cool breeze blowing into millions of households come from? From the sweat of the power workers, from the scheduling of the power supply department, from the Zhuo Jueye's insurmountable efforts in Hubei Electric Power ...

Implementation of electricity during the peak summer

Deploy power scheduling and repair drills in advance

The continuous increase in power load has continued to increase the pressure of Wuhan Grid. Under the continuous pressure, it can still ensure the stable power consumption of residents, and the preparation of the power supply department is indispensable.

Jimu Journalists learned that during the peak summer, the State Grid Wuhan Power Supply Company strengthened power scheduling on the one hand, cooperating with government departments to urge power plants to do a good job of coal storage, gas storage and elimination, and ensure the peak power of the power plant in the area; on the other hand, also Actively carry out emergency drills to greatly improve the ability to deal with emergencies.

At about 4 pm on August 16th, the staff of the State Grid Wuhan Power Supply Company found that a main transformer at 220 kV Erfei Mountain Transformer Power Station was too high and there were hidden equipment hazards in the inspection and inspection temperature of the electricity.

"Beyond" to repair Erfei Mountain Transformation Station

As all the equipment of the station operates in the recent full load, the State Grid Wuhan Power Supply Company has launched a full -chain cooperation processing mode such as regional electricity preservation, transfer load, comprehensive repair, and user visits. The hour was shortened by more than half, and more than 600,000 people in the entire power supply area spent the "sharp peak time" of the substation in the night of the power station in the night from August 16th to 17th.

Since July, the State Grid Wuhan Power Supply Company has arranged a total of 240 emergency repair teams, more than 1,900 repair personnel, more than 450 repair vehicles for 24 hours, with a total of 1,5372 person -times and 2634 vehicles, and made every effort to carry out power guarantee.

At the same time, the company also organized 20 -tape electric operating vehicles for high -temperature weather non -stop power repair, and organized 39 emergency power vehicles such as various types of electric vehicles, energy storage vehicles, and UPS vehicles for emergency power supply during the failure period.

"Zero Awareness" with power operation and intelligent special patrol

The work of working is good for the first time. In the face of the strongest high temperature in the past 62 years, behind the stable power consumption of citizens in Wuhan is the strong support of various types of power grids.

Beginning in June this year, more than a dozen Wuhan Power grid key summer projects including 220 kV Zhaojiabao, Miao Mountain's main mutual expansion, 110 kV Xiangyun, Yujia head expansion, and Sanjintan expansion projects successively sent electricity to operation, put into production, and put into production. The transmission line reaches 6,216 kilometers and the transformer capacity reaches 1.77 million kVA, which can still play a key role in stabilizing the power supply to residents when the power load is rising.

In addition to ensuring power supply supply, power supply employees also feel security at the front line of high temperature protection power supply.

On August 12, in the ancient post road in Paifang Street, Jiangxia District, Wuhan City, the power supply company of Jiangxia District, Wuhan City, State Grid adopted a transformer to increase the wiring of transformer to ensure the "cool life" of the surrounding residents from being disturbed.

Under the hot sun, the temperature temperature is far more than 40 ° C, and the insulation service becomes a "sweat suit" at high temperature. After more than an hour of intense operations, the increasing wiring task was successfully completed, and more than 200 users under the "zero perception" method were used to ensure the cool summer.

In addition to the power -based operation, the intelligent power grid inspection mode is also an important measure for this summer to supply power supply power supply and efficiently to ensure stable power supply.

On August 23, Yang Sanchun, a substation of power supply and dimension in the Wuhan power supply company of State Grid, controlled a multi -rotor drone and inspection robot "Electric Xiaobai". Model, carry out high -temperature special patrols for the 220 kV pot top power station equipment, and timely discover hidden dangers of defects.

Intelligent inspection of the substation of the substation

"In the past, a substation of a substation required at least two people and 1 car, which took 3 hours. Now it only needs to be controlled in the background and can be completed in 50 minutes." Yang Sanchun said that the hidden danger of the use of the intelligent inspection model is compared to the manual inspection. It has been improved by 2 to 3 times, and the inspection efficiency has been increased by 3 to 4 times compared to before.

Since July this year, the State Grid Wuhan Power Supply Company has used intelligent equipment such as remote intelligent inspections, drones, and mobile inspections to carry out three -dimensional inspections, discovered and deal with various types of defects in a timely manner, and carried out a total of 1200 special patrols. 946 key substations, 5,985 processing defects.

Comprehensive mobilization needs response and saving electricity usage

Entering mid -August, Wuhan continuously issued high -temperature red warnings, with the highest temperature of multiple days exceeding 40 ° C. At the critical moment of electricity explosion -type growth in the city, the State Grid Wuhan Power Supply Company initiated a new model of social joint preservation of electricity with electricity demand and power consumption. It organizes 19 demand to respond to combat command and monitor the power grid load 24 hours. Fully win the victory of the Wuhan Power Grid Conference.

Under the leadership of the government, the whole society mobilized, "let the electricity be on the people" successfully implemented, and many enterprises and businesses have actively adjusted the rhythm of production and reduced energy and consumption. In order to make electricity in the people, Midea factories located in Wuhan Economic Development Zone actively adjusted production plans to make enterprises more efficient.

In addition to adjusting the rhythm of production, the enterprise's various energy conservation and consumption reduction measures are also playing a role. Midea has invested a number of high -efficiency energy -saving equipment such as air compressors, and the daily electricity consumption saves 12,000 degrees of electricity. For enterprises that reduce energy consumption during the peak period of electricity consumption, Wuhan City gives subsidies for 20-25 yuan per kilowatt.

"According to the rate of turning on a family, two or three air conditioners, we should allow more than 2,000 residents to use air conditioning during the peak. Increase the production line hours, the current output can be guaranteed." Minister Jia Zhigang introduced.

The scope of implementation of the demand side response is getting larger and larger, and more and more participating subjects. As of now, Wuhan has participated in a total of 23,383 households in response to the needs of the enterprise, and nearly 9026 participants participated in the execution.

Power supply workers continue to keep on the front line of electricity guarantee

"The load curve is normal, and the electricity use of residents and important users is normal." At 2 am on August 21, State Grid Wuhan Power Supply Company Hanyang Customer Service Center employee Shi Dongjie reported the load of the day in the work group.

At this point, he had adhered to his post for 12 days.

"Comrades start monitoring loads, arranging corporate power consumption, and guiding their peaks until 8 o'clock in the morning, and they have to be busy until 3 am the next day." Shi Dongjie said that during the high temperature period, the residents of Hanyang area were always normal. Stable use of electricity to make this continuous and firm effort is more valuable.

At 2 am on August 16th, Zeng Liang, an employee of the State Grid of Wuhan State Gong Economic Development Zone, was "rushed" home. At 4 am the day before, Zeng Liang's wife was about to come to the basin. He was also "rushed" by his colleagues: since the high temperature continues, Zeng Liang has participated in power supply for 15 consecutive days, and often does not go home for several days.

Implement "zero perception" repair at night

At 2 pm that day, after accompanying his wife to usher in the baby, Zeng Liang rushed back to the front line ...

Faced with the high temperature and continuous power load of more than 40 ° C, there are still many power supply employees who have continuously fought on the front line of power supply like Shi Dongjie and Zeng Liang. They are like the breeze and stars on the summer night, guarding the coolness and light of millions of households.

High temperature may soon come to an end, and the power supply department's long -term service service will continue. As of now, the State Grid Wuhan Power Supply Company has established 3327 power supply service grids in the city, actively incorporated into 1293 communities and 1918 villages. 1240 grid staff covered 5,268 community WeChat groups. Response the power consumption of residents.
