On June 16, the reporter learned from CRRC Zhuzhou Institute that the wt3300d146 wind turbine unit developed and integrated multiple intelligent fan technologies was successfully hoisted in Yunnan huomuliang wind turbine farm. Previously, this type of wind turbine has been operating without fault for 18 months at an altitude of 3000 meters in the northwest. It is reported that this is also the highest altitude, single unit power and the largest diameter of wind turbine installed in Southwest China.
Successful hoisting of the largest land fan in Southwest China
Huomuliang wind farm is located in huomuliang Tang area, Ninglang Yi Autonomous County, Lijiang City, Yunnan Province, with a total installed capacity of 49.5mw. The local terrain of the mountainous area fluctuates greatly, the mountainous area alternates with gullies, the terrain is complex and irregular, the altitude is between 3300-3600m, the air density is between 0.81-0.85kg/m3, which is a typical high-altitude wind farm.
This time, the high-altitude wind turbine hoisted by the wind farm is a new generation of flagship model developed by CRRC Zhuzhou, which integrates multiple intelligent wind turbine technologies such as wind direction compensation strategy for maximizing energy capture at a specific site, active reactive power control, low self consumption control technology, optimal pitch angle technology, multi beam dynamic super power technology, etc. the comprehensive power generation is 7% higher than that of the traditional model The noise level is 1.5 dB lower than that of similar products. Modular transmission chain split technology also greatly reduces the cost of mountain transportation and hoisting.
Huomuliang wind farm is located in huomuliang Tang, Ninglang Yi Autonomous County, Lijiang City, Yunnan Province, with a total installed capacity of 49.5mw. The local terrain of this area is characterized by large undulation, alternating mountains and gullies, extremely complex and irregular terrain, and the altitude is between 3300m and 3600m, which belongs to a typical high-altitude wind farm.
According to the characteristics of the wind farm, CRRC Zhuzhou has carried out refined micro site selection and designed a set of customized unit solutions. Previously, this type of wind turbine has been in trouble free operation at an altitude of 3000 meters in the Northwest for 18 months, the reliability of the unit has been inspected, the power characteristics have passed the inspection of the international authoritative certification agency, and the market order with a total capacity of more than 1 GW has been obtained continuously.
In the early stage of wind power development in China, Northeast China, North China and Northwest China are the focus of development. However, due to the complex terrain, high altitude, thunderstorm and humidity in summer, and the frequent occurrence of ice and snow on roads in winter, the development cost is very high, which is almost regarded as the "development forbidden area". Thanks to the rapid progress of domestic high-altitude wind power technology, Yunnan has become a large province of wind power with a large number of fans.
CRRC Zhuzhou Institute is one of the first complete machine manufacturers to explore high altitude wind power in China. In 2009, it completed the development of high altitude series wind power units. After being launched to the market in 2010, it carried out batch installation in Dali, Eryuan, Guizhou Jiucaiping, wujiangyuan and other wind farms in Yunnan Province. The good operation performance of nearly 1000 high altitude units in several wind power plants has been praised by the industry.
