Recently, the journalist of this journal has learned that the South East Exploration and Design Research Institute of the China Electric Power Construction Group, which has developed hydroelectric and has a history of 71 years of development, has entered the field of wind power since the beginning of the 20th century and 1990s. The capacity of the wind power machine that has participated in and developed in China by the end of 2020 has reached Escort manila has reached Escort manila href=”https://philippines-sugar.net/”>Sugar daddy reaches 40 million kilowatts, accounting for about 18% of the total wind turbine capacity in the country. Its investment and construction projects such as the Tulane Wind Venue (including Lebang Wind Venue, the vast Wind Venue, and the strong Wind Venue) have successfully invested and produced economic and demonstration value.

Sugar baby “It can be said that in China’s renewable power field, we are both ‘pilots’ and ‘pilots’.” Zhang Feng, deputy general manager of the South East Institute of Electric Power Construction, said.

Recently, the “Most Beautiful Wind Field” event report group of this magazine came to the vast wind-drink field to explore how China Electric Power Engineering South East Institute can hold hands with the Chinese-Car Zhuzhou Power Motor and Motor Research Co., Ltd. (hereinafter referred to as “China Electric Power Zhuzhou Institute”), using innovation as a breakthrough, breaking the limitations of resources and environment, realizing the useful application of wind-energy resources in high-altitude areas, illuminating the green development path of the southeast region with the light of technology, and raising energy for the strategic transformation of national wars.

The most important economic benefits are experience

Duran Wind Field, located in Dulan County, Haixi Prefecture, Qinghai Province, with a total capacity of 199,500 kilowatts, including 49,500 kilowatts in Lebang Wind Field, 50,000 kilowatts in vast Wind Field, and 100,000 kilowatts in Tungfeng Field. Among them, Lebang Wind Field was merged online in August 2017; Haomiao Wind Field was merged online in September 2018; Tinhao Wind Field Phase I (50,000 kilowatts) was merged online in December 2019, and Phase II (50,000 kilowatts) was merged online in April 2021.

The altitude of the site of this project exceeds 2900 meters, with an average annual wind speed of 6 meters per second, which is a typical high-altitude low-wind speed wind scene. In addition, in the desert, the construction of the project is difficult.

Zhong Kangtai, the head of Qinghai District, investment and transportation company of China Electric Power Construction South East Institute, introduced to reporters using the vast wind scene as an example. The machine hoisting operation is in summer, with the lowest temperature being loaded at -20℃, and the construction period is very tight. The transportation of large parts still requires passing through culverts, etc. In response to this situation, the owner of the business has strengthened the coordination with the transportation department toAs well as the same industry, the high and low-level links are connected, and the nearby manufacturing and purchasing major components are ensured that the project is on schedule. After the commissioning, the flight itinerary of the vast wind venue was stable.

In 2019, at an average wind speed of 5.8 meters/sec, the annual application hours reached 2,162 hours. Among the other five project targets around, the Haomiao Radio Venture Field surpassed the second place in the annual application hours of Sugar Baby over 162 hours and was rated as the “AAA” radio Venture Field by China Telecom.

In 2020, with an average annual wind speed of only 5.64 meters/sec, the total power generation of this wind venue was 99.06 million kilowatts, and the annual application hours copywriting was 1981 hours.

In the first half of 2021, it was brilliant on June 2 – bright, beautiful and charming. The broadcast of the program allowed her to power the 5000 kWh of electricity at a 4-meter/second 5Sugar daddy0.64 million kilowatts, and the application hours were close to 1,013 hours, and it was expected to exceed 2,000 hours throughout the year.

In addition to economic benefits, based on its own performance positioning, the owners pay more attention to the demonstration value generated by project development.

“From the perfection of the national policy system, to the development of the industry, and then to the implementation of the project, the design institute plays a role in the new year that leads to the past and the “military” style.” Zhang Feng pointed out, “We invest in these projects not just to focus on economic growth. Instead, we hope to buy the entire industry chain, gain valuable experience from it, and provide innovative support for local governments and industry innovation. “

As a professional survey and design organization, China Electric Power Construction South East Institute has undertaken 4Sugar baby The planning tasks of the national tens of thousands of kilowatt-level risk base and a number of total contracting businesses of more than 10 countries and regions have laid the foundation for itself in the wind./a>The location of the electric field.

In the 14th Five-Year Plan, my country’s wind and electricity industry has been comprehensively moving towards average prices online, and the southeast region has long become the main battlefield. But based on the actual situation, the wind-limited phenomenon of projects such as Dulan Vent Field is more serious. Solving and resolving problems online is still the most pressing task in the development of new forces and high-quality development in the southeast region.

In this regard, Zhang Feng suggested: First, accelerate the construction of the delivery channel and release the binding renewable power distribution and green power certificate purchase and sale mechanism as quickly as possible. Second, we are suitable for high-energy-consuming industries such as coal-to-emission gas and coal-to-oil with higher added value, and strive to develop major data industries based on dynamic industries. The third is to promote the construction of a dynamic base with divergence such as wind and water replenishment and wind and heat accumulation.

Five models show the technical foundation of the same field

Far away, the wind scene in the Tulane is in the blue dome, the vast desert is vast, the mountains are like ink paintings, the wind turbines are moving, and the scene is full of spectacles.

It is clear that the third phase of the project has installed five types of WT1500D93H70, WT2000D121H85, WT2200D131H90, WT2500D136H90, and WT3600D146H100 produced by China Railway Zhuzhou.

As we all know, the high-altitude areas in the southeast have low air density, strong ultraviolet lightning, large wind and heavy thunder. The technical team of the China Railway Zhuzhou Institute has carried out a large number of bullets on the machine according to the characteristics of the environment. escortFitness design is like the use of rubber coat materials with UV-resistant functions for motor covers and wheel covers; add the number of lightning protection connections to expand the cross-sectional area of ​​the guide wire under lightning protection in the leaf sheet; improve the power of the heater in the machine control cabinet and tower base cabinet. From the market situation, these measures have caused good consequences, and the average application rate of the organization is above 99%.

“The first radio motor used by our company is the Chinese car brand. Their machine functions are good and the fault rate is low,” said Xu Kangtai.

It is worth mentioning that WT36When Sugar daddy00D146H100 machine was put into operation, I founded the largest single record of installed wind turbines in China with the largest number of installed wind turbines, including the highest installation altitude records.

Introduced by Wu Xianning, deputy director of the Technical Department of the China Railway Zhuzhou Institute of China Railway, this machine is the latest generation of mainland air-fire flagship product with complete independent intellectual property rights developed by China Railway Zhuzhou based on the 3.x MW platform. The single machine capacity of the 3.x MW platform can be flexible to adjust between 3.0~3.6MW, and the matching wind speed is 146~160 meters, suitable for the “Three Norths” base and the low-speed area in the southeast.

In terms of environmental adaptability, the 3.x MW platform adopts a new design that is anti-storage and UV-resistant, which greatly enhances the machine’s ability to resist bad environments; the natural and ventilated water cooling design greatly reduces the cooling effect of the machine’s unit and reduces operating noise.

In terms of power generation, with the help of stream generators and dynamic reorganization super dual technology, the 3.x MW platform can adjust the mating to the best power development status by itself, fully discovering the potential of wind energy resources.

In addition, the module design features of the 3.x MW platform well solves the problem of large-capacity machine hoisting in high altitude areas. By using the separating lifting technology, the machine TC:
