, like a rafter, a giant pen, depicts the blueprint of power grid development, and serves Zhang Yuan, a new journey,
————, State Grid , Zhangjiakou Power Supply Company, 70 years of development documentary
, in Zhangjiakou, every people's life is always inseparable from electricity, and electricity, as the most basic necessity of life, has been integrated into all aspects of society. 70 years of singing and 70 years of passion, Zhangjiakou's power supply business has grown together with the New China; 70 years of hardships and 70 years of change of life, Zhangjiakou's power supply business has been brilliant together with the New China. In the blink of an eye, the State Grid Zhangjiakou Power Supply Company, which is responsible for the power supply task of 37,000 square kilometers, has played an important role in the economic development and social life of our city. In particular, in recent years, the annual sales volume exceeds 10 billion yuan, creating intelligent transmission channels, building a smart grid, helping to prepare for the 2022 Winter Olympics, and building a Zhangjiakou renewable energy demonstration zone... These prides of Zhangyuan are all engraved with the hard work and sweat of Zhangyuan's power supply personnel.
"Where will aspire to go. If you don't have a distance, you can't reach it. If you can't be limited by mountains and seas, you can't limit it. Wherever you want, you can't enter. If you have a sharp army and a strong armor, you can't control it." People need a little spirit. This is true for individuals, and the collective is no exception. In the 70 years of development and transformation, State Grid Zhangjiakou Power Supply Company has taken Zhangjiakou's development as its mission, guided by Party building, never forget its original aspiration, keep its mission in mind, build a strong smart grid that is compatible with the regional economic and social development, implemented the rural grid transformation and upgrading project with high quality, enhanced the power supply capacity of urban and rural power grids, accelerated the transformation of the power grid development mode, stood at the forefront of the road of development forward, fought against the huge waves, like a "giant ship" with enough horsepower, breaking through the waves, using the earth as paper, poles as pens, and sweat as ink, leaving a series of sonorous and solid footprints on the vast land of Zhangjiakou, and composing a series of exciting and progressive music.
Don’t forget your original intention
Light up the lamp in the hearts of the mountain village people. In the wilderness on Zhangjiakou Basin, silver windmills stretched out huge wind leaves, rotating continuously at a height of dozens of meters. The photovoltaic arrays are endless, and the green electricity emitted is continuously transported to the Beijing-Tianjin-Tang Power Grid through the power grid, and has become a new hope for poor farmers to get rid of poverty and become rich. But who would have thought that Guyuan and Shangyi County in the Bashang area were not connected to the power grid until the mid-1980s, realizing power supply to the county and county. Today, stable electricity has reached thousands of households, making important contributions to changing the poverty landscape in Zhangjiakou’s rural areas.
On January 31, 1985, when the 110 kV transmission line of Zhangbei to Guyuan 110 kV was completed and the 35 kV was started with load operation, the last county in the province, Guyuan County, was powered, marking that Hebei Province has achieved power supply and county power supply and also marking that Zhangjiakou has achieved power supply and county power supply. In the 1950s, Guyuan County had almost no industry, and this grain-producing county could not even guarantee the use of lighting, and the diesel engine power generation was intermittent. In 1968, after the power grid of Zhangbei County was operated, the 300-horsepower diesel engine and 2 million kilowatt generator that were retired from Zhangbei Power Plant were transferred to the source, and the county town could use 3.3 kV voltage to supply power. In 1970, the county established a power plant, and in 1974, the installed capacity reached 500 kilowatts and the annual power generation was 700,000 kW. In 1983, the 110 kV power transmission and transformation project in Guyuan County was started and the Guyuan 110 kV substation was built. On January 31, 1985, the Zhang-Gu 110 kV transmission line was operated, and the county town held a grand celebration with more than 30,000 people. In the evening, the whole county town was brightly lit, and people felt the charm of electric lights under the high-voltage sodium lamp.
Based on the power supply of counties and counties, Zhangjiakou Power Supply Company strives to speed up the pace of power supply in every village and every household: At the end of 1993, there were still 250 administrative villages in our city located in the old mountainous areas and remote areas on the dam on the mountain. Based on this consideration, the power supply company launched the Guangming project, built four 35 kV substations with 74.2 kilometers of lines, erected 615 kilometers of 10 kV lines, added 231 distribution transformers 5510 kVA, and built 183 kilometers of new low-voltage lines. On November 12, 1996, with the power transmission in Niangzicheng Village, Baicao Township, Wei County, all administrative villages in our city were powered on. Behind the achievements is Zhang Yuan’s power supply man who silently contributes.In the deep mountainous area in the southern part of Wei County, in order to send the electric poles to the village, they need to transport them by car, then pull them by car, and finally carry the electric poles to the mountain with manpower. In the farthest village, the transmission workers have to carry the electric poles to walk about 10 kilometers of mountain road.
1998 to 2005, in the context of the country driving domestic demand to promote economic growth, Zhangjiakou Power Supply Company successively implemented rural grid transformation projects and county power grid transformation projects in accordance with the requirements of the government and superior companies, and completed more than 700 major power grid transformation projects, and completed 2 billion yuan in power grid construction investment. In 2006, the household power supply project was implemented, and 290 kilometers of new 10 kV line was built, which sent electricity to 98 natural villages in 11 counties, benefiting 1,754 households and 4,942 people. On October 20, 2006, in Fenggou Village, Xiejiabao Township, Zhuolu County, as the power switch at the village head was closed, the current was passed to every household in the mountain village, and every household in this village used electricity. Since then, Zhangjiakou City has realized "energy for every household".
Only by not forgetting your original intention can you achieve the end. Every cadre and employee of Zhangjiakou Power Supply Company will turn the "original aspiration" and "mission" they shoulder into the cohesion of all difficulties to do the cause of the Party and the masses and the spirit of rolling up their sleeves to work hard; into the spirit of innovating thinking, thinking more ways to find scientific solutions when party members and cadres encounter difficulties, forming a joint force to solve problems and solve difficulties, and breaking through the difficulties encountered in the process of promoting power grid infrastructure construction.
2017-2018, State Grid Zhangjiakou Power Supply Company based on its own responsibilities and based on the work attitude of "finding its own positioning, giving full play to the advantages of enterprises, solving practical problems, and serving poverty alleviation", starting from the key points of poverty alleviation, understand farmers' demand for electricity in poverty alleviation, and launching targeted new service measures such as "three-level docking, one-to-one external, unconditional construction" to effectively solve the problems of power grid supporting and power services of poverty alleviation projects in poor villages, and help the needy embark on the road to prosperity. For example, in 2017, 792 public transformers and some 35 kV substation main transformers were completed, and more than 700 village-level power grids and multiple 10 kV and 35 kV lines were transformed; in 2018, 28 centralized photovoltaic power stations such as Zhangbei 100 MW poverty alleviation project and 577 village-level photovoltaic power stations were launched. At present, 1.237 million kilowatt photovoltaic poverty alleviation power stations have been connected to the grid, covering 88,838 registered poor households, accounting for 39% of all registered poor households, making clean energy and electricity illuminate the direction of poor farmers to get rich.
Remember the mission
Create a large channel for Zhangyuan New Energy Output. Vibrant wind towers stand on the vast Zhangyuan land, stretching for hundreds of kilometers; rows of crystalline silicon plates absorbing sunlight are neatly arranged in the barren mountains and slopes, with a vast area. The development of the scenery industry has made our city unlimited "scenery".
Zhangjiakou has unique wind and solar resources. Since January 1997, the first wind turbine was hoisted at the Great Wall Wind Farm located in Batou, Zhangbei County, setting a precedent for wind power generation in Zhangjiakou and even the "Beijing-Tianjin-Tang" power grid. By the beginning of the last century, the "giant" of new energy development "big" such as Huaneng Group , Datang Group , Huadian Group , Guodian Group , Guohua Energy, and China General Nuclear Corporation "landed" in Zhangjiakou. Our city has successively become the first million-kilowatt-level wind power base in the country and the first city to build a double million-kilowatt-level wind power base in the country. Zhangjiakou's renewable energy industry has achieved vigorous development and has become a new engine for local economic development. "Strive for the happiness of the Chinese people and the rejuvenation of the Chinese nation is the primary aspiration and mission of the Chinese communists and the fundamental driving force that inspires generations of Chinese communists to make heroic efforts." General Secretary Xi Jinping's words are resounding!
Instructions are heard, and ambitions are all in your heart. The road ahead suddenly became clear due to the far-sighted blueprint.
With the continuous expansion of installed capacity of wind power and photovoltaic power generation, grid connection has gradually become a problem and bottleneck that has plagued the development of this emerging industry. In order to support the development of Zhangjiakou's renewable energy industry, Zhangjiakou Power Supply Company takes the development of new energy as its mission and strives to open up the regional new energy export channel, so that the power grid development will be moderately ahead of the development of wind power and photovoltaics.In order to successfully deliver new energy, the company's power grid builders worked hard and overcome all difficulties. They built power stations and silver lines in the bitter and cold places outside the border, among the mountains and ridges...
"The wind blows and the electricity flies." In order to cooperate with the construction of a million-kilowatt-level wind power base in Dashang, Zhangjiakou Power Supply Company launched the first phase supporting delivery project of the wind power base. On September 2, 2010, with the successful grid-connected power generation of the China General Nuclear Corporation Friendship Wind Farm, the first phase supporting delivery project of the million-kilowatt-level wind power base in Dashang, with a total investment of 1.5 billion yuan, was completed and put into production six months ahead of schedule. A total of 1 500 kV substation was expanded, 3 new 220 kV substations and 9 transmission lines were built, and 220 kV substation capacity 1,860 megavolt-ampere and 540 kilometers of transmission lines were added.
In order to fundamentally break through the bottleneck of renewable energy power grid connection, Zhangjiakou Power Supply Company cooperates with the superior company to take the lead in trial and promote the implementation of a number of demonstration projects: On December 25, 2011, the world's largest trinity-in-one wind and light storage demonstration project, the first phase of the National Wind and Light Storage Storage and Transmission Demonstration Project, was completed and put into production in our city; on March 14, 2013, the closing of the low-voltage distribution circuit breaker in Hebei Province, Zhangjiakou Baosheng New Energy Technology Co., Ltd., was successfully connected to the grid to generate power; on April 3, 2015, the 500 kV "three stations and four lines" project was officially put into operation, adding 1.55 million kilowatts of wind power transmission capacity to Zhangjiakou City, becoming the second major channel for new energy transmission in Zhangjiakou City.
In July 2015, the State Council approved the establishment of the Zhangjiakou renewable energy demonstration zone. In order to realize this grand blueprint, through the active efforts of Zhangjiakou Power Supply Company, State Grid has designated our city as the "Global Energy Internet Zhangjiakou Innovation Demonstration Zone". The company has taken this opportunity to strive to build an intelligent power transmission channel. On December 27, 2017, the world's first new energy power station with virtual synchronous machine function was completed and put into operation at the Zhangbei National Wind and Light Storage and Transmission Demonstration Power Station in our city. The biggest technical problem of new energy grid connection was overcome in one fell swoop; the world's highest voltage level and largest output capacity plusmn; the 500 kV multi-terminal flexible DC demonstration project started construction in February 2018. At the same time, the 1,000 kV ultra-high voltage line project in Zhangbei-Xiong'an New District was officially started on March 15 this year. In order to ensure that these two key projects are put into production as scheduled and to ensure the full completion of the six major projects involving the Winter Olympics, the company launched the "100-day battle and decisive victory in 2019" special action on September 20. After the project is put into production, our city's "green electricity" can be directly transported to Xiongan New Area, and the bottleneck of the output of renewable power energy will be completely broken.
data shows that as of the end of 2018, the city's renewable energy cumulative installed capacity was 13.4548 million kilowatts (12.8148 million kilowatts connected to the grid), accounting for 74.2% of all power installed capacity. According to the Energy Research Institute of the National Development and Reform Commission, the proportion of renewable energy consumption in Zhangjiakou City in 2018 has exceeded 23%, ranking at the national leading level.

It is particularly worth mentioning that in terms of helping the preparation of the Winter Olympics, Zhangjiakou Power Supply Company innovatively proposed the concept of "Party Building + Winter Olympics", giving full play to the role of the party organization as a fighting fortress and the role of party members as pioneers and models, taking the power grid pioneer party branch, party member commando team, responsibility area, and demonstration post as a starting point to promote the majority of party members to be pioneers, set examples, and achieve achievements in the company's major work, explore a practical path to deeply integrate party building work and central work, and gather the motivation for the preparation of the Winter Olympics.
For large and medium-sized enterprise customers, deepen the application of mobile operating terminals. Zhangjiakou Power Supply Company implements on-site reply to the 10 kV customer power supply plan, and online signing or centralized review of the power supply plan for 35 kV and above; for projects restricted access to the power grid, "access first, then transformation" or transition plan access is implemented, and the distribution network upgrade and transformation work is started simultaneously; for low-voltage small and micro enterprise customers, the power supply plan approval is cancelled, and the completed power transmission is carried out together with various majors for inspection, and the meter is installed and power is sent on the same day. Comprehensively implement the "project pre-arrangement, project implementation first, project approval" working model, implement integrated exploration plan design, synchronously promote acceptance, metering installation, and power transmission work, and quickly respond to market demand; for large and medium-sized enterprise customers, in principle, the 10 kV supporting power grid project is completed within 30 days; 35 kV and above projects are synchronized with the customer's internal projects or moderately advanced. For small and micro enterprise customers, in principle, the completion is completed within 5 days, and the extension of low-voltage public lines involves completion within 10 days. "It took less than a week from application to power-up. I originally thought that it would take at least one week to go through various approval procedures." A relevant person in charge of Zhangjiakou He Animal Husbandry and Breeding Company said.
"The bigger the heart, the bigger the stage." In recent years, the electricity consumption environment in our city has become more and more stable, and the power outage time is less and less. The strong backing for reliable electricity use is inseparable from the unremitting efforts of Zhangjiakou Power Supply Company. Zhangjiakou Power Supply Company has implemented urban distribution network power supply reliability improvement projects and rural electrification projects to build a reasonable grid structure, improve equipment health level, optimize distribution network operation mode, accelerate the speed of grid fault repair, comprehensively improve the ability to operate without power outages, and continuously reduce the average annual power outage time and number of power outages for customers. The efficiency of emergency repair of power grid faults has been continuously improved. Through panoramic monitoring of distribution network operating conditions and intelligent fault analysis, the fault points are accurately positioned, and the power outage range and user lists are obtained in real time. Through SMS, APP, WeChat and other channels, information such as fault outages, emergency repair progress and planned re-energy are actively pushed to customers "point-to-point" through SMS, APP, WeChat and other channels; the "grid" active emergency repair model is fully implemented to realize one work order, one team, and one solution, reducing customer power outage time.
