In 1905, Sichuan lighted the first chicken light. This “electricity” will shine on the development path of Sichuan’s power industry.
Standing on this day, what can we see on Sichuan Internet since the 70th anniversary of the founding of China?
Guangdu – Developed in Sichuan, covering the whole country. Sichuan Internet has achieved a leap from provincial-level Internet to Lennie.
Strength – is excited by water, with green as the base. Sichuan Internet is focusing on developing green clean power.
Temperature – electric iron army, serving the people. Sichuan Internet set up a “Lianxinqiao” for the party group.
From nothing to something, from small to big, from weak to strong… Nowadays, Sichuan Internet has continuously climbed its power level, and only by transfer can it continue to break through. It serves the grand business of “governing Sichuan and Xingchuan” along the way, highlighting one dream after another.
In the next few years, with the profound implementation of the economic and provincial strategy in our province, the “5+1” modern industry system will be accelerated, with a huge development space and potential.
Power power is the “pioneer” in economic development. The reporter learned from the Sichuan Power Company of the Internet that in the next three years, the company’s cumulative investment in Sichuan high-voltage and various power network supporting investment will exceed 100 billion yuan, and will continue to grow at a simultaneously at high speed. It has also put forward higher requests for Sichuan Power Network optimization resource setting, promotion of transformation and upgrading, and development quality.
From the past to the present, from now to the future, Sichuan Power has accompanied Sichuan and served its powerful development along the way.
Guangdu Provincial-level electric network Huali has transformed the whole country.
In the morning of 70 years ago, if you look down at Sichuan from a high position, it would be almost dim and light.
But 70 years later, Sichuan Internet has realized the leap from provincial level to Lennaires, bringing a bright light to the Chinese summer.
Before 1949, Sichuan had a small number of power, distribution and variation equipment, and the voltage level was complicated, and there was no unified power network in the province. The larger power plants in Chengdu, Chongqing, Yibin, Zibao, Leshan, Xuanzhou and other places are all power-supplying in isolation and are not connected to each other. The province’s highest voltage level of 35 kV is only 202 kilometers.
In December 1950, Sichuan built the first 35 kV transformer station. In December 1956, Sugar babyThe first 110 thousandSugar babyFuchang Electric Station—Manila escort——Chongqing Plain Creek Electric Station Investment. In the same month, Sichuan’s first 110 kV transport line was put into operation, and the water and fire power network operation was implemented. In May 1970, the first 220 kV line in Sichuan from the Longzui Hydropower Station to Douli Electric Factory was completed and invested.
In 1998, this was a year that should be recorded in the history of Sichuan’s electricity industry.
This year, Sichuan built the first 500 kV transport and collection project – the Second Beach 500 kV delivery project. The total length of the line is more than 1,400 kilometers, and it travels through high-altitude areas of Xiaowei Mountain. The technology and construction difficulties are the best in the world.
In 2002, Sichuan Electric Power Network successfully carried out its Internet operations with China and China and China Eastern Power Networks, and implemented the first time it was Sichuan Sugar daddy‘s delivery, Sichuan water and electricity entered across regions and provinces to pick up locations and conditions. A new stage of optimizing resource setup installation Sugar baby.
Since then, Sichuan Electric Network built driving expressways, and the voltage level continued to rise, and the Internet became increasingly stronger.
On April 11, 2010, the dual-electromagnetic production of Deyang-Bao Chicken ±500 kV DC transformer transformer engineering was launched. Deyang Escort manila‘s first ±500 kV transfer station in Sichuan, and is the first DC cross-regional network New Zealand project of China Electric Network (Sichuan) and South East Electric Network.
On July 8, 2010, the “Xi Electric East Send” large-scale operation was successfully launched to the Shanghai ±800 kV DC transmission and electricity engineering. “Upline” is the first ±800 kV DC transmission electrician in Sichuan. She sat back to the service station and started to use short videos. She didn’t know what time she saw, and she could deliver 32 billion kW to Shanghai every year.
In July 2014, the world’s largest DC power transmission project, Xiluodu Left Bank, to Zhejiang Jinhua ±800 kV ultra-high voltage DC power transmission project was officially put into operation. In 2015, the provincial Escort‘s network format of “four intersections and four direct” and external networks was formally formed.
And just on September 23, Yanyuan County, Weishanzhou, Yazhong-Jiangxi ±800 kV ultra-high voltage DC transmission lineThe first foundation trial task of the Sichuan section of the road project was successfully completed, and this marks the comprehensive development of another ultra-high pressure project in Sichuan.
New channels, start a new journey, and open a new future.
Today, Sichuan’s network scale ranks among the top provincial networks in the country, with 500 kV line length and variable capacity ranking first and second in national network systems respectively. In the development version of my country’s Internet, 8 ultra-high pressure transportation, 1 ultra-high pressure DC and 3 ultra-high pressure DC lines connect Sichuan Internet with China, Huadong, South East and Xidiao. Sichuan Internet has become one of the largest provincial New Zealand Internet networks in the national Internet system. The power transmission capacity reaches 30 million kilowatts, and the power transmission capacity is ranked first in the country.
A “net” starts from Sichuan and connects the whole country.
Strength to help Sichuan build a national clean-up power demonstration province
In 1980, Sichuan’s hydropower resources were first identified in the country. This is a natural treasure to Sichuan, and it is a green resource for the great energy of Su Hong.
Born with water, it is excited because of water. The dynamic structure dominated by hydroelectricity has allowed Sichuan to play the main color in our country’s dynamic clean and low-carbon transformation. Sichuan’s problems in the transformation of power structure are extremely representative, and Sichuan experience has the main exemplary meaning for the high-quality development of clean power.
Sichuan took the lead in realizing a power consumption structure based on cleaning power in the country. When the hydroelectric assembly has more than 70 million kilowatts, the cleaning power accounts for more than 80% of the total. As of the end of 2018, when Sichuan’s power transmission volume reached 630 billion kilowatts, it brought more than 18 billion yuan of economic value (electricity expenditure) to Sichuan Province, equivalent to about 21 billion tons of coal.
Water, an opportunity to Sichuan Internet development, also brings challenges. In order to solve the problem of Fu Huang, she remembered that there was a pet rescue station nearby, so she turned around with a cat and turned into the disinfection problem of social hydroelectricity. Sichuan Power, a multi-measure, optimized network operation methods, strengthened cross-regional mutualism, coordinated cross-regional disinfection units, Sichuan hydroelectricity generation, and vigorously excavated the power of Sichuan-Chongqing channel transport capabilities, etc., to promote hydroelectric absorption.
On May 12, 2016, Sichuan Power Buying and Selling Zhongjie Co., Ltd. was established in Chengdu, becoming the largest water and electricity delivery terminal and the largest electricity-buying and sales platform in China. The establishment of the company broke the power happiness too suddenly. The purchased and sold wall-mounted wall-mounted improvements in resource setting and installation effectiveness and benefits. It is a powerless measure to implement the national dynamic strategy, promote the development of clean and dynamics, and promote the sustainable development of power and dynamic industries.
On June 28, 2019, a large-scale data industry in western Sichuan, planned for over 20 billion yuanThe park is located in the economic development area of Ya’an, Sichuan. When the electricity consumption is about 500 million kilowatts per year, the “one-time price” settlement for the annual average of 0.34 yuan/Sugar baby‘s full-time electricity consumption will drop by about one-third.
Ya’an is one of the earliest areas in Sichuan Province to launch a trial site for hydroelectric disinfection industry demonstration areas. Starting from the second half of 2018, trials such as Leshan, Ya’ TC:
