In China’s 9.6 million square kilometers of wide six-square-kilometers and 3 million square kilometers of Pengpai waves, the dynamic feast is nowhere to be there.
The rivers in the northeast are rushing down, the sunshine in the southeast is like a waterfall, the wind in the northeast is endless, and the coal in the north is thriving…
A nationally unified network allows this dynamic feast distributed throughout the world to flow. The power generated by a drop of water, a long light, a piece of wind, and a handful of coal will all reach thousands of households and far away through the network.

The “Flower of Mobility” solves not only the power gap and redundant resource allocation, but also the carrier of social progress. It determines the careers chosen by the people on this area and the modern ecological civilization they hope for. With 70 years of evolution, our country has embarked on a unique Internet development path and built a powerful, safe and intelligent Internet network that is “tailored” for China. It not only makes it common for Chinese people to use electricity today, but also makes people use more clean electricity and green electricity.
It’s hard to start in a thousand holes
Time goes back 70 years ago. That year, the Chinese, who had been fighting the fire and hardship, finally ushered in a new starting point, waiting for a hundred miles to be excited and waiting for a hundred miles to be waiting for a hundred miles to be waiting for a hundred miles to be waiting for a hundred miles to be waiting for a hundred miles to be waiting for a hundred miles to be waiting for a hundred miles to be waiting for a hundred miles to be waiting for a hundred miles to be waiting for a hundred miles to be waiting for a hundred miles to be waiting for a hundred miles to be waiting for a few miles to be waiting for a few miles to be waiting for a few miles to be waiting for a few miles to be waiting for a few miles to be waiting for a few miles to be waiting for a few miles to be waiting for a few miles to be waiting for a few miles to be waiting for a few miles to be waiting for a few miles to be waiting for a few miles to be waiting for a few miles to be waiting for a few miles to be waiting for a few miles to be waiting for a few miles to be waiting for a few miles to be waiting for a few miles to be waiting for a few miles to be waiting for a The Internet left by Old China is a network with severe damage, backward technology, and broken support. According to data records, in the early days of the establishment of New China, in addition to the 154-200 kV high-voltage network in the Northeast region, a 77 kV network with weak connections was built in the Beijing-Tianjin-Tangzhou region, and a 33 kV power supply network in Shanghai, a single 22 kV or 33 kV power line was installed in a separate location or in a large area, and almost no forming power system was formed. At that time, the vast rural areas were almost Sugar daddy had no electricity, and the power supply in the city was extremely scarce, so power shutdown and power limit were common.
Academician Lu Zheng, who participated in the college entrance examination in the 1950s, remembers his memory of the days when he was preparing for the college entrance examination. At that time, in addition to lighting equipment, there were few other household appliances in common urban households. During the summer days, Luqiang’s home town, Anhui, had a temperature of 42 degrees high. There was only one electric fan at home. Due to the unstable voltage, this unique electric fan was also “powerless”, and Luqiang was so hot that he was exposed to prickly heat.
Under the leadership of the Communist Party of China, national electric power industry began the recovery mission of the power industry. The Internet has also entered the stage of orderly development. However, under the past thinking of “re-release and light supply without any consideration”, the founder of our Internet was just a matter ofThe power supply and delivery project exists, without the concept of network, let alone the unified planning.
“As mentioned above, he was unintentionally stretched out to the male supporting role who was trampled by the male protagonist and was slapped. At that time, power was developed in large industries. If there was a large industrial user in a certain place, he would build a power plant for the large user and then build a supporting “delivery and collection project” to ensure the demand for industrial electricity, such as the Danjiangkou power station sent to Wuhan Steel Electric is a classic example. With this development thinking, the power supply construction foundation has been planned, but the power network construction foundation has not been planned. The power supply and collection project has been replaced by the above-mentioned ‘delivery project’. With the continuous development of the power industry, the format of power supply and power network planning has been gradually formed. The thinking and method of power supply and power network design is gradually formed. “Lu emphasized. With the continuous construction of power supply scope and power supply transformation projects, high-voltage power networks in various places have begun to develop faster.
Northeast, recognized as the “chief of the Republic”, is the snatch of the industrial development of New ChinaSugar daddy. Steel, petroleum, machine tools, shipbuilding, military engineering, etc. are the pillar industries of Northeast China. In terms of the power industry in New China, Northeast China also plays the role of the opener. Relying on Fengfeng Hydropower Factory, Hydropower Factory and Liangpo Lake Hydropower Factory, Northeast China has a relatively large network system with a relatively large scale in the early days of the founding of New China. Our country’s first 220 kV high-pressure electric circuit was also born in this black ground disk.
The construction of a 220 kV high-voltage transport circuit is related to the delivery needs of Fengfu Hydropower Factory. At that time, important power supply and energy-saving power plants in the Northeast region gradually recovered power generation. The three northeastern provinces, especially the Guangning Heavy Industry Base, demanded a large amount of electricity use, and the original line capacity could no longer meet the needs of industrial production. At the same time, in order to prevent being affected by the Korean War and to improve the reliability of power supply to Ning Province, our country decided to design and build a 220 kV Songdong Lilu Road Line by itself. This line was one of the 156 key projects in my country at that time, with the project agent “506”.
At that time, the highest voltage level of electricity network running abroad was the 380 kV transmission line built by Sweden in 1952. The 220 kV transmission line was still the world’s advanced level at that time. In the world, only a few countries such as american and Su Lian had independent design and construction capabilities. For China at that time, this project was extremely challenging from research and development design to construction.
On July 20, 1953, the 220 kV high-pressure electric wire in Songdong Li Line broke ground and operated. The line starts from Fengfeng Hydropower Station on the Second Songhua River in Jilin, and goes from the 50 Taiwan Transformer Power Station to Lishizhai Transformer Power Station in the northeast of Ningcheng City. It passes through mountains, hills, mountains and depressions, and cross-domain rivers 32. In the case of no large construction equipment at that time, the employees of the business carried the shoulders and backs. In the cold winter at minus 30 degrees northeast, several ten people carried a guide line together and shouted the number to climb up the mountain. Under such unlimited conditions, the construction workers successfully completed the project with great enthusiasm. In January 1954, the project was put into operation, with a construction period of only 6 months, and the investment time was 67 days earlier than the original plan. In 1955, the National Email Department issued a special mail ticket to commemorate.
The Sugar daddy is the first 220 kV high-voltage transport circuit in my country. The Songdong Lilu Road Project has a milestone in the history of the construction of the New China Internet. Its investment not only provides electricity protection for industrial development in the South China region, but also lays a solid foundation for the power transformation industry in New China and opens up a new situation.
During the First Five-Year Plan period, my country has built some power networks with different differences in 35 kV, 110 kV or 220 kV, which has strengthened the connection and adjustment between various power generation factories, strengthened economic operations, expanded the regional scope of power supply, and greatly reduced the power supply, providing greater power supply, providing further development of national economic construction.
Pin fingers a swing. The voltage level has been falling again, more than ten years later. In 1964, our country hit a higher voltage level – the 330 kV tail sound opened.
This time, the electric voltage level of this transport is still related to the water Escort power station. This time the water comes to the tributary of the H TC:
