Memorabilia of Gansu Electric Power in the 40 years of reform and opening up: electric power construction promotes clean energy consumption

● in 1985, the 330 kV transmission line from Gansu Jingyuan power plant to Ningxia Qingtongxia substation (Gucheng) was completed. Ningxia Electric Power Co., Ltd. and Shaanxi Gansu Qinghai Electric Power Co., Ltd. became one of the five largest electric power companies in China at that time

● in 1989, the first unit of Jingyuan power plant, the first pithead power plant with more than one million kW in Gansu, was put into operation for power generation

● in 1997, Yumen Jieyuan wind farm, the first wind farm in Gansu Province, generated electricity, with an installed capacity of 12000 kW

● in 2005, the first 750kV power transmission and transformation demonstration project in China - the 750kV power transmission line and two 750kV substations from Guanting, Qinghai to Dongda, Lanzhou, Gansu turned off the speed valve handle to supply oil in a counterclockwise direction to lift the piston 40 kilometers away from the cylinder bottom, filling the gap of voltage levels above 500kV in the history of power transmission and transformation lines in China

● in 2007, the "household power supply" project of Gansu large power extension was fully completed, involving 79000 households and 358000 people in 12 cities and prefectures of the province

● in 2009, the construction of China's first 10 million kW wind power base started in Jiuquan. Up to now, the installed capacity has reached 920 kW

● in 2010, the 750 kV Hexi three station three line power transmission and transformation project, including Hexi 750 kV substation, Dunhuang 750 kV substation, Jiuquan 750 kV substation and their lines, was successively completed and put into operation, laying a solid foundation for the power transmission of Jiuquan 10 million kW wind power base

● in 2014, the ± 800 kV Hami South Zhengzhou UHV DC transmission project was completed and put into operation, becoming the "power Silk Road" connecting the western border and the Central Plains

● in 2017, the first large-scale clean energy transmission UHV DC transmission project in China - ± 800 kV Jiuquan Hunan UHV DC transmission project was officially put into operation

● Gansu section of ± 1100 kV Changji Guquan UHV DC transmission project will be completed in 2018, and the whole line is expected to be completed by the end of the year

people say that the "scenery" in Longshang is good, and love leads thousands of miles. On the ancient Silk Road, the tower is high and the line is continuous, supporting the clean energy on the Hexi Corridor and running to the distance

wind power and photovoltaic power generation in Gansu have been closely related to electricity since the beginning of their development. Since the first batch of wind turbines were put into operation in Yumen in 1997, Gansu new energy has gradually grown and expanded, accompanied by the rapid development and full support of Gansu Power

power construction has been constantly upgraded

in 1997, Jiuquan, the first wind farm in Gansu, Yumen Jieyuan wind farm, was built and generated electricity. Gansu wind power started from this

one September several years later, kanghailong, 23, came to work in this wind farm. At that time, there were only a few bungalows and a small courtyard, and the wind farm stood on the Gobi desert. Later, he became the director of the wind farm

according to kanghailong, the number of wind turbines in Jieyuan wind farm has grown from 4 with a total capacity of 12000 kW to 38 with a total capacity of 21600 kW by the end of 2003, with a small increase. However, at that time, the development of wind farms in Yumen, Guazhou and Dunhuang had been gradually accelerated, and a number of small and medium-sized wind farms, such as MAZONGSHAN, Dingxin and Yumenguan, had also started wind measurement planning

according to the requirements of the national "Eleventh Five Year Plan", Gansu provincial Party committee and government put forward the goal of "building Hexi wind power corridor and rebuilding the land Three Gorges in the west" in 2006. In may2010, the general office of the State Council issued several opinions on further supporting the economic and social development of Gansu Province, which clearly proposed to "accelerate the integration process of Jiuquan and Jiayuguan, and actively develop new energy and equipment manufacturing industries such as wind energy and solar energy", providing policy support for the development of clean energy industry in Gansu

on August 8, 2009, the construction of China's first ten million kilowatt wind power base started in Jiuquan. Jiuquan 10 million kilowatt wind power base has become another landmark project of China's western development after the west to east gas transmission, West to East oil transmission, West to East power transmission and Qinghai Tibet railway. In the second year, the installed capacity of photovoltaic power generation in Gansu reached 20000 kW

in fact, before the vigorous development of clean energy, Gansu Electric Power has gone through an extraordinary road

as early as 1972, Qin'an substation, the first 330kV substation in China built by Gansu Power Transmission and Transformation Engineering Co., Ltd., was put into operation, and Gansu Power took the lead in stepping into the threshold of 330kV in China. But in the early stage of reform and opening up, the pace of development of Gansu Electric power industry is relatively slow. In 1978, the installed power generation capacity in Gansu was only 2.795 million KW. By the end of 1985, the installed power generation capacity had reached 3.0696 million KW

40 years, Gansu Electric power industry has undergone a series of changes: from the traditional hydropower and thermal power generation to the vigorous development of new energy such as wind power and photovoltaic power generation; From the initial lack of electricity to the current surplus of electricity; Gansu Power has become the power exchange center of Northwest China, with a power exchange capacity of more than 20million kW across provinces and regions. By the end of 2017, the installed power generation capacity in Gansu Province had reached nearly 50million kW

On September 19, 2003, the first 750kV EHV power transmission and transformation project in China - 750kV Guanting Lanzhou East power transmission and transformation demonstration project started construction. Gansu Electric power is moving towards 750 kV

Wang Jun participated in the construction of 750kV Lanzhou East substation. He was the project manager in those days and is now the director of Safety Supervision Department of Gansu Electric Power Construction Company. Standing in hongliangying village, xiaoxiaoying Township, Yuzhong County, where Lanzhou East substation is located, he said: "there is no road here! We are building on a wasteland. We are ahead, and the road always follows us."

Gansu Electric Power Co., Ltd. has followed the footsteps of electric builders. During the "Eleventh Five Year Plan" period, Gansu Electric Power main frame basically realized the upgrade from 330 kV to 750 kV. In 2010, the substation capacity and line length above 110 kV were 2.5 times and 1.6 times that of 2005 respectively

Gansu Electric Power has laid a solid foundation and strong support for the development of clean energy. In november2010, Xinjiang and Northwest 750 kV joint project and Jiuquan 10 million kW wind power base phase I export project were completed and put into operation. Since then, Xinjiang electric power has said goodbye to the history of isolated operation, and the export channel of tens of millions of kilowatts of wind power in Gansu has been opened

make every effort to serve the development of clean energy

2012, caoyujun and his wife cuilihong seldom met. They met three times, all at the railway station. Each time, they stood outside the station for a few minutes. Before they said a few words, the station broadcast began to urge him to get on the bus. Caoyujun and cuilihong are both employees of Gansu Electric Power maintenance company. One is the monitor of the automation class and the other is the operator

in 2012, when their husband and wife were far away from each other, the 750 kV secondary channel between Xinjiang and Northwest China has not been completed. Today, caoyujun is engaged in the inspection and maintenance of 750 kV channel 1 and channel 2 of the main connection between Xinjiang and Northwest China

2012, based on the 750kV Gansu Xinlian project, the ± 800kV Hami South Zhengzhou UHV DC transmission project and the 750kV second channel project of Xinjiang northwest main link were fully started, accelerating the construction of a "hard channel" for Gansu Power to receive, consume and send clean energy, making it possible to optimize the allocation of energy resources in a wider range

2012 is also an important year in the history of clean energy development in China

in June of this year, China's combined wind power was 52.58 million KW, taking 4 Adjust the distance between the two pressure plates of the experimental machine (click the rise or fall button on the software with the left mouse button to adjust the fixture position). The United States has become the world's largest wind power producer. National power has become the largest and fastest growing wind power in the world, and the ability of large power to operate wind power is at the world leading level

also in this year, the installed capacity of wind power in Gansu Province reached 6586600 kW, and the installed capacity of photovoltaic power generation reached 863500 kW. The total of the two reached 7.4501 million kilowatts, surpassing hydropower as the second largest energy in Gansu

with such large installed capacity of wind power and photovoltaic power generation, the test of electricity is huge and unprecedented

Gansu Electric Power attaches great importance to the problem of large-scale integration and consumption of clean energy, and is committed to promoting the construction of "hard channel" and "soft support"

Gansu Electric Power Co., Ltd. strives to change the power development mode. While carrying out its own green operation, it fully supports the development of clean energy, speeds up the construction of strong and intelligent power, creates a green platform for energy allocation, promotes the unified planning and coordinated construction of wind power development and power, speeds up the construction of wind power transmission and transmission supporting projects, and strives to improve the capacity of large-scale wind power consumption. The system will automatically analyze the experimental data and curves to ensure that wind power is timely and. In 2011, the wind power supply in Gansu increased by 70 times compared with that in 2006

Gansu Electric power is expanding, on the one hand, towards higher voltage level, on the other hand, towards weak agriculture, distribution and reinforcement. In 2013, the "power supply to every household" was realized within the extension scope of Gansu Dali power; Gansu section of ± 800 kV hazheng extra high voltage DC transmission project was also completed in the same year

201 is characterized by great impact, short action time and rapid change. On July 7, 2003, the 750kV Shazhou substation was completed and put into operation, becoming an important part of the 750kV power transmission and transformation project of the second channel of the main connection between Xinjiang and the northwest. The operation of the station not only provides an important channel for the transmission of wind power and photovoltaic power in Jiuquan, but also creates favorable conditions for the development of energy resources in Dunhuang

the continuous improvement of the electric frame has paved the way for the transmission of clean energy in Hexi corridor

On June 9th, 2017, on the Gobi desert in Jiuquan, a team of more than 40 bicycles started from the ± 800 kV Qilian converter station and rode to a wind farm in front

in order to celebrate that Jiuquan Hunan ± 800 kV HVDC transmission project successfully passed the 168 hour test run assessment, the employees of Gansu Power Transmission and Transformation Engineering Co., Ltd. expressed their joy in this way

14 days later, the whole Jiuhu project was officially put into operation. This is the first large-scale clean energy transmission UHVDC project in China, which plays an important role in solving the bottleneck of clean energy consumption in Gansu

Zhou Rui, who once served as a technician in the construction of Jiuhu project, joined the 750kV Zhangye substation project in 2018 as the civil engineering project manager

Zhangye substation is an important part of the 750kV third channel strengthening project of Hexi corridor. The station is located at the south foot of Longshou mountain in Qilian Mountains, surrounded by a grassland. The station is located on a hillside, with great flood control pressure. In August this year, Zhou Rui encountered a flood when he first entered the site of the station. In order to prevent the flood, he led the construction personnel to build a flood retaining wall and a flood diversion ditch around the substation

on October 25, the pilot pouring ceremony for the first foundation of the 750kV Zhangye line of the third channel strengthening project of Gansu Hexi corridor was held, and the line project entered the comprehensive construction stage. This is another clean energy transmission project started by Gansu Electric Power Company after the completion of Hexi 750 kV second channel power transmission and transformation project

after the completion of the 750 kV third channel strengthening project of Hexi Corridor, the static stability limit of Xinjiang Gansu link road can be increased from 9million kW to 12million kW, which can meet the needs of the subsequent development and export of the 5million kW wind power project supporting Qi Shao DC

silver lines cross the horizon of Hexi corridor. Standing on the hillside of Pingshan Lake Grand Canyon in Zhangye, the wind is howling, ± 800 kV mid day UHV DC transmission line, ± 800 kV Qishao UHV DC transmission line, ± 1100 kV Jiquan UHV DC transmission line
