On September 8, 2022, as an important part of the world's first high -voltage exchange demonstration project, the 1,000 kV high -voltage Nanyang Station ushered in a safe operation for 5,000 days. The webmaster Chen Kai and the duty operation and maintenance personnel in Nanyang Station were wearing work clothes. They took the flashlight one after the other, walking in the UHV main device area to inspect the entire station's oil -supply equipment.

On January 6, 2009, the world's first commercial operation, which was independently developed and designed by my country's independent high -voltage exchange project, was launched by 1,000 kV. High pressure era.

The 1,000 kV high -voltage Nanyang Station located in Nanyang area is just like the "bridge" of the project. His left hand holds "Changzhi", his right hand pulls "Jingmen", and contacted the two major power grids in North China and Central my country in China. Every year, when the water and electricity period of China and Huazhong and Huazhong is full, the project transmits the water and electricity of Huazhong Grid to the North China Power Grid to achieve the role of energy saving and emission reduction. During the dry period of the south The power of the power grid, complementary advantages, peak peaks, and cross -regional compensation.

From high voltage to ultra -high pressure, from ultra -high pressure to UHV, with the drums of economic development, China's long -distance transmission technology has made rapid progress. At present, the highest voltage level of China Grid has reached 1,000 kV and DC ± 1100 kV, and the transmission distance of a single line has exceeded 3300 kilometers. China has become the country with the highest voltage level in the world.

After 5,000 days, the test demonstration function of 1,000 kV Jinnan Jingte high -pressure exchange test project was perfectly implemented. 5000 days of "test demonstration", 5000 days of safety and stability, what did it bring to Henan? How did they do it?

Henan Power Grid currently has 13 special high -voltage lines to land or transit (7 DC lines account for half the country). The planning and construction of 4 special high -voltage lines under construction (1,000 kV Nanjing Ⅱ, Yuwu I, Yuwu Ⅱ line, ± 800 kV Shaanxi-Henan Line) is the core of my country's Western Power East Transmission, Northern and South Mutual Aids, and the core of the "Japanese" glyst high-voltage grid in Central China. It plays a key role in other aspects.

1,000 kV Jinnan Jingte High -pressure Exchange Test Project Cross -Shanxi, Henan and Hubei provinces, the Yue Huang River and the Hanjiang River pass by 654 kilometers. Through this "power flight" The "Express" of thermal power only takes 0.002 seconds to Henan. In the past 10 years, the amount of electricity to Henan Power Grid through Nanyang Station was 3.376 billion kWh, accompanied by Lingbao's back -back project, ± 800 kV high -voltage day DC project, ± 800 kV high -pressure Qingyu DC project, and was put into operation. Henan Power Grid took the lead in entering the era of special high -voltage communication and DC operations, forming a "two intercourse and two direct" UHV backbone grids. It provides a strong guarantee for meeting Henan's economic and social development demand, promoting energy cleaning low -carbon transformation, and ensuring that Henan energy security has been provided.

As of 00:00 on September 8th, 1,000 kV high -voltage Nanyang Station runs safely for 5,000 days safely. As a hub station of the two major power grids in China and North China, the cumulative exchanged power is 213.2 billion kWh, and the power of electricity to Henan Power Grid is 129.6 billion kilowatt -hours. Reduce 59.61 million tons of coal combustion in Henan and reduce carbon dioxide emissions by 160 million tons.

In 2013, 1,000 kV Jinnan Jingmen's high -pressure exchange test demonstration project -related technologies, listening to the highest honor of the Chinese science and technology community, the National Science and Technology Progress Award Special Award. The world's first high -voltage exchange test demonstration project has been established. How to transport a high -voltage grid well and manage the first set of high -voltage equipment is a difficult test on the first generation of high -voltage people.

At the beginning of the establishment of the station, in the face of the relatively weak technical strength and lack of experience in the on -site work, Nanyang Station fully realized that the improvement of the quality of personnel is the key to protecting production safety. The heavy responsibility. The masters tirelessly one -on -one, handle the skills of hand -to -hand, seize all available time to organize in -site training and on -site training, explain the technical points and operation standards, tell and remind them to care for life and pay attention to safety; teach them to look at drawings, use it, use it with Instruments, adjustment equipment, discover problems, solve problems, and teach them the rich experience accumulated in work practice for a long time; guide them to operate the equipment on the spot, and continue to grow in the work tasks again and again ... Under the teachings of the master's follow -up and the teachings, the level of business of the entire station has continued to improve, and it has grown rapidly into a combat collective with a strong knowledge and specialized quality.

Over time, Nanyang Station slowly summarized a set of effective education systems. It is to sign the "Teachers and Belt" agreements, with new and new training, and establish a "goal -plan -measures -assessment -assessment- The closed -loop training system for improvement, in -depth analysis of common problems and personality cases, accurately teaching and training "general doctors", maintenance of "specialist doctors" and "surgeon" teams. There are more than 200 professional talents such as scientific research, including 38 engineers, 15 senior engineers, and 3 provincial excellent skills experts. For 5000 days, after the operation and maintenance personnel's exploration test at night, the operation and maintenance personnel of Nanyang Station solved the problems of operating under various methods such as the annual maintenance, extremely harsh weather, and multiple faults of the UHV equipment. Good equipment lean and differentiated operation and maintenance, in -depth "three -in -agency improvement" (integrated operation and maintenance, autonomy of maintenance, and normalization of emergency). Since the operation, 1,000 kV high -pressure Nanyang Station has completed a total of 15,5312 pouring operations, 3678 work tickets are processed, and 3072 are eliminated and abnormal. More than 6,000 hidden dangers are governed, and the ranking of energy availability, energy utilization, equipment failure rate, and key hidden danger governance rate index ranking in the country has been achieved in the forefront of the country.

The National "Workers Pioneer", the "Advanced Party Branch" of the State Grid, the "Advanced Collective" of the Provincial Electric Power Company ... The certificates are shining on the wall, as if telling the "soldiers" of Nanyang Station in 5,000 days. s story. "Now that you have chosen high -voltage, you must return to its glory and dignity with your own efforts. It is good for the high -voltage grid, carbon and carbon and carbon, which is the firm belief in our team. The mental state and the unprecedented struggle attitude, creating new achievements in the process of the new era, "said Chen Kai, the webmaster of Nanyang Station.

At present, the construction of Nanyang -Jingmen -Changsha 1000 kV high -voltage communication line project has been approaching the end. After the operation, Nanyang Station will increase 1,000 kV transmission lines, 1,000 kV and UMC, 1,000 kV switch 2 Group. This project is the first high -voltage project to start construction during the "Fourteenth Five -Year Plan" period of our province, and it is an important part of the "Japan" glyph ring network in Central China. After the completion of the project, it can significantly improve the power exchange between Hubei and Hunan and Hunan, and it is of great significance for strengthening the structure of the China -China Power Grid grid and promoting the economic and social development of Central China.
