"Light up" the "engine" social development of the people's life

"In the eyes of others, this is just a work record, but in my heart, it is a history of Yanbian power development." On July 1, in the bright conference room of the State Grid Yanbian Power Supply Company, from the post of power engineers Elder Yang Liande, who retired for more than 20 years, held a working log in his hands and took a reporter to review the development process from weak to strong and power supply since Jianzhou.

In 1966, 26 -year -old Yang Liande became a technician of the Yanbian Electric Power Bureau Test. From the day he joined, all the changes in work and Yanbian Power Grid will seriously remember the book and persisted until retirement.

Yang Liande told reporters that in the early days of Jianzhou, the highest voltage level of Yanbian Power Grid was 110 kV, 66 kV and above lines, with a total length of 422.26 kilometers, 66 kV and above power stations, 17 transformers, and a total capacity of 34,000. Kissy. The overall scale of power power is small, and problems such as backward technology and insufficient supply capacity cannot meet the development of economic and social development and the needs of people's lives. At that time, the rural areas in Yanji City had not been powered on, and there was electricity in urban and suburbs alone.

In order to improve the power supply, in April 1967, the Yushuchuan Power Plant began construction. On October 3, 1970, the first 12,000 -kilowatt -transmitting power unit was connected to the network, and a total of 3 units were put into production. The installation capacity reached 49,000 kilowatts. The power supply tensions in Yanbian areas, but Yanbian Power Grid still has problems such as low power quality and unstable frequency. The power supply is unreliable, and the power equipment configuration is poor. It is very easy to cause a large -scale power outage caused by accidents. In 1978, the power distribution line broke 211 times and sent the electric line to the trip 38 times.

In order to cope with the shortage of power and protect the power equipment, in the 1970s and 1980s, governments at all levels and electrical industry bureaus established the "San Electric Office", which stipulated that the factory and mining enterprises and users must use the indicator. County and city factory and mining enterprises adopt a rotation system. In order to avoid the peak period of electricity, ordinary people can only get up early and cook at three or four in the morning. Insufficient power and electricity have caused frequent power -to -line power -to -line power -limited power, which not only causes huge power loss, but also seriously affects production and life.

Social development, power first. After the reform and opening up, Yanbian Power Grid gradually entered the stage of rapid development. In January 1985, Yandong changed and the 220 kV mirror Dunyan line was completed and put into operation, and Yanbian Power Grid officially entered the 220 kV voltage level era. In November 1987, Yanbian Power Grid runs from the east grid of Heilongjiang Province, and is officially incorporated into the main network of Jilin Province through the 220 kV 蛟 蛟 蛟. One year later, the Hunchun Power Plant officially connected the power generation to provide sufficient power resources for Yanbian area. In December 1997, the second change was realized, marking the entry level of Yanbian Power Grid into the new era.

"Beginning in 1998, our state has vigorously implemented the construction and transformation of urban and rural grids, and the development of the power grid has continued to achieve new leaps." Entering the new century, after retiring, Yang Liande still cares about the development and changes of Yanbian Power Grid. Yanbian's grid grid structure, technology equipment and overall functions have been comprehensively leapfrogged, forming 500 kV as the backbone mesh, 220 kV Shuanghuan network covering 8 counties (cities) in the state, basically eliminating power transmission bottlenecks, Agricultural Netnet The shelf is no longer weak, and the "low voltage" problem has been fundamentally solved, especially with the continuous rise in the total installed capacity of various types of power plants, the power supply of Yanbian has continued to increase. As of the end of 2021, the annual electricity sales of Yanbian Power Grid reached 5105.12 million kilowatt -hours. The main variable capacity and annual electricity sales volume increased by 3015.4 times and 87.6 times compared with 1952. Yanbian Power Grid, which has been on the "intelligent" train, has become an inexhaustible momentum for Yanbian's economic and social development.

"You see, now every family is full of electrical appliances, use it casually, rest assured, the streets and alleys at night are even more light. The bus running on the street becomes an electric car. The advanced power grid makes our lives bright and comfortable. Let our society get better and better! "Blowing the cool air conditioner, Elder Yang Liande told the progress of the grid and lamented the important role of electricity in the production and life of the masses. Intersection

——The interview notes-

The reporter followed the memories of the elderly Yang Liande, "walking" through the years of the long -term power outage of power out of power, and then the powerless population was used to use power, village village power electricity, cleaning and heating ... The mapping is all generations of electricity people, which to meet the people's struggle for the needs of the people. In the past 70 years, the quality of the people in the state has risen, and the quality of life of the people in the state is as high as sesame flowers. The silver line lights up the lights, and the electricity supports the happiness of the people. Under the more and more complete power grid "engine", Yanbian is getting better and better.
