The 300billion blueprint of the hottest wind power

The 300billion blueprint of the wind power giant raises doubts

the large-scale prosperity of the wind power plan will be destroyed; When placing the pressure testing machine, look west from Jiayuguan, on the west of Hexi Corridor, on the vast Gobi adjacent to Xinjiang, rows of silver windmill giants, thousands of miles in formation, hundreds of miles in camp, and paddles whirling, which is magnificent

Gansu wants to build it into the world's largest wind power base in more than ten years, and turn the former world wind farm into a wind power capital

Gansu plans to take three steps: first, by 2015, the installed capacity will reach 10million kW; The second step is to increase the installed capacity to 20million kW by 2020; Third, after 2020, Wang Wentao, chairman of Huasheng Jiangquan group, and Gao Honglu, general manager, will continue to expand the installed capacity to more than 30million kW

at that time, the installed capacity will exceed 50% of the Three Gorges power station, equivalent to building 10 Gezhouba power stations or 18 Daya Bay nuclear power stations, and the known total investment scale will reach 300billion yuan

but in front of this beautiful blueprint, there are also difficult problems: where to send electric energy, how to adjust peak and frequency, and who can become the end user of wind power

take advantage of the wind

Gansu is located in the northwest inland, with few opportunities for rain. Most areas have a dry climate, belonging to the temperate monsoon climate with strong continental. A relevant person from the Gansu Provincial Development and Reform Commission said: in the past, the northwest wind blew over the hillside, bringing yellow sand and loess, leaving behind poverty and desolation; Today, people see the value of wind and find the dawn of new energy

it is reported that the Hexi Corridor in Gansu Province is rich in wind energy resources, especially the Guazhou County in Jiuquan City, the desert area in Yumen City and the Mazong mountain area in Subei, known as the world's wind reservoir. The theoretical reserve of wind energy resources in the whole Hexi Corridor is about 200million kW, and the exploitable wind energy in Jiuquan City alone is more than 40million kW

in 2006, the Gansu provincial Party committee and government put forward the strategic concept of building the Hexi wind power corridor and rebuilding the western land Three Gorges. Lu Hao, Secretary of the Gansu provincial Party committee, specially wrote a research report on a grand strategy related to the overall situation, and clearly put forward the long-term goal of three steps to finally achieve the installed capacity of 30million kW

since then, the construction of wind power has suddenly accelerated. More than 20 well-known enterprises, such as China Guodian Longyuan Group, Datang Group, China Power Investment Group, and China Guangdong Nuclear Power Group, are running horses and enclosure in the Hexi corridor

in 2008, the total installed capacity of wind power generation in Gansu Province exceeded 1million kW, and five wind farms have been built in Jiuquan area. By the end of 2009, the total installed capacity has more than doubled to 2.2 million KW

in fact, it is only a conservative expectation to achieve the installed capacity target of 10million kW by 2015. According to relevant sources, according to the current planning and construction speed, the total installed capacity of wind power will reach 5.16 million KW by the end of 2010 and 12.71 million KW by 2015

in Jiuquan City, 2 since the elimination of friction in 2008, on average, a 50000 kW wind farm has been under construction every month. The tall windmill rotates rhythmically under the breeze of the Gobi. The local villagers say in an exaggerated and humorous tone: that's money! One turn is 20 cents. Count how many turns does it take a day

technological bottleneck

in fact, Gansu has not advanced alone. The development of wind power in the neighboring Xinjiang and Inner Mongolia autonomous regions started earlier. The installed capacity of wind power built and under construction in Xinjiang is 750000 kW, and the total planned installed capacity of wind power in 2010 is expected to reach 3.55 million KW; The installed capacity of wind power in Inner Mongolia exceeded 3million kW at the beginning of 2009

on August 8, 2009, the commencement ceremony of the first phase of Gansu Jiuquan ten million kilowatt wind power base, the world's largest wind power project, was held at Jiuquan Yumen Changma wind farm

after the exciting news came out, some people of insight also made different voices

Jiang Qian, chief researcher of CIC's new energy industry, believes that the construction of Jiuquan wind power base is an attempt to solve the problems of blind construction, scattered layout and too small scale in the current development of wind power. But he then pointed out that the development of wind power in Gansu should take Inner Mongolia as a mirror. According to reports, although Inner Mongolia currently has the largest installed capacity in the country, about one-third of the wind power installed and power generation projects are idle due to the difficulty of wind power installed and power generation

CIC consultant pointed out in a report that the current technical bottleneck of the wind power industry cannot be broken through, resulting in high costs, blind investment in wind power equipment, relatively backward power equipment, and the lack of technical specifications for wind power still plagued the wind power industry. Therefore, to realize the dream of a real wind power, the installed capacity is not the only indicator, and the overall progress of the industrial chain is the key to the healthy development of the wind power industry

in fact, Gansu has long been aware of the problem of wind power and external transmission. In March 2008, the 750 kV ultra-high voltage power transmission and transformation project in Guazhou, Jiuquan, Lanzhou was started. By the end of 2009, Gansu Electric Power Company invested, constructed and managed the 750 kV wusheng BaiYin Power Transmission project when exploring a new development path of plastic granulator technology

a 750 kV transmission line is not enough. According to the advance assumption of Gansu Provincial Development and Reform Commission, the planning and research of the positive and negative 800 kV HVDC transmission project in Hexi Corridor has been fully launched

in addition to the technical problems of electric energy transmission, Gansu has been troubled by the problems of frequency modulation and peak shaving of electricity and electricity consumption. A relevant person from Gansu Electric Power Company said that if all 20million kW wind power is to be delivered from Hexi, another 20million kW hydropower or thermal power must be built in the wind power corridor, but it is impossible to build large hydropower stations in the Hexi Corridor due to water shortage. Similarly, because thermal power needs water cooling, it is useless to build large-scale thermal power due to lack of water

it is learned that at present, Gansu power can bear the peak shaving power generation capacity of about 1.5 million KW, which simply cannot meet the peak shaving capacity requirements of future wind power stations

experts are still worried about a problem: even if the problems of electricity transmission and frequency modulation and peak shaving are solved, where will electricity be sold? It is estimated that the maximum power load in Gansu Province will reach 9.5 million kW in 2010, and the sales of electricity will reach 56 billion kwh. Obviously, Gansu cannot use up the huge wind power at all, or even use it

due to many bottlenecks that are difficult to break through, the wind power industry in Gansu is in the vortex of doubt. Some people say that blind development will lead to a great leap forward in wind power and overcapacity. Some people also said: This is the collective kidnapping of local governments by energy enterprises, and the enclosure in the West ignores local affordability

multi way breakthrough

at a recent briefing, Gansu Electric Power Company said that it had received the support of the State Power Corporation and was planning to sell wind power to Sanhua region, so that South China, North China and central China would become end users of Gansu wind power

if the sales problem is solved, how to solve other problems? It is understood that Gansu is currently using multiple ways to break through, trying to use high starting point planning and high standard construction to vigorously promote wind power construction

it usually takes 1 to 3 years to master detailed wind energy data through wind measurement. At present, Gansu is taking advantage of the opportunity of the new round of national wind energy resources census to carry out a detailed survey and comprehensive evaluation of resources in areas rich in wind energy resources, grasp the distribution and change law of wind energy resources in detail, and establish a wind energy resources database to provide reliable data support for the location of wind farms

the key to the success or failure of the construction of wind power base lies in power. At present, Gansu Electric Power Company is accelerating the extension of 750 kV ultra-high voltage power project to the wind power base in Hexi Corridor with the support of the state power company. The planned plus or minus 800 kV UHV DC transmission is trying to connect central and Northern China

while accelerating the construction of the wind power base in the Hexi Corridor, Gansu is making full use of coal, hydropower and solar energy resources, striving to achieve the complementarity of wind power and thermal power, hydropower and optoelectronics, so as to ensure the stable operation of electricity and the safe transmission of wind power. In Hexi Corridor, at present, the two largest 10 MW photovoltaic power stations in China have begun to be built in Dunhuang, of which 1 MW of the 10 MW photovoltaic power stations built by SDIC Huadian has been officially put into operation; China's first desertification photovoltaic power station Datang Wuwei solar 1 MW power station has been completed and put into operation. It is reported that Jiuquan city plans to achieve 2million kW of optoelectronic installed capacity by 2015, and Jiayuguan City plans to achieve 500000 kW of total optoelectronic installed capacity in the long term

Gansu also hopes that through the operation and management of wind power and local transformation, wind power can generate gold on the ground, develop high-tech high value-added high-load energy industries that adapt to the characteristics of power sources in wind resource rich areas, develop energy storage industries such as electrolytic water hydrogen production and high-capacity power battery charging, and cultivate emerging industries such as water pumping and energy storage power stations, which have been put on the agenda

Gansu provincial Party committee and government have repeatedly stressed the need to focus on improving the R & D and manufacturing capacity of wind power equipment. At present, Gansu has planned wind power equipment industrial parks in Lanzhou, Jiuquan, Baiyin and other cities, striving to form an industrial cluster integrating R & D, manufacturing, certification, testing, training, parts supply and service, and building Gansu into an important wind power equipment manufacturing base in the country
