In recent years, with the increasing awareness of environmental protection and the gradual deterioration of the ecological environment, the state has paid more and more attention to the development of clean energy. At the same time, with the improvement of energy storage technology, wind energy power generation solutions have become one of the important directions for the development of renewable energy in the world.
Since the implementation of the Renewable Energy Law of the People's Republic of China in 2006, the development and utilization of wind energy in the mainland has developed rapidly, and the cumulative installed capacity of wind power in the country has grown by more than 100% for four consecutive years from 2006 to 2009, and since 2010, it has maintained a good momentum of rapid development. According to statistics, as of 2012, the mainland (excluding Taiwan) has installed 7872 new wind turbines with an installed capacity of 12960MW; a total of 53764 wind turbines have been installed, with a total installed capacity of 75324.2MW, with an annual growth rate of 20.8%. The total installed capacity of the mainland has ranked first in the world for three consecutive years. The stock of wind turbines in the mainland is at the leading level in the world。
According to the mainland's "Twelfth Five-Year Plan for Renewable Energy", by 2015, the cumulative installed capacity of grid-connected wind power will reach 100 million KW, and the annual power generation capacity will exceed 190 billion kWh。 Among them, the installed capacity of offshore wind power has reached 5 million KW, basically forming a complete and internationally competitive wind power equipment manufacturing industry. By 2020, the cumulative installed capacity of grid-connected wind power will reach 200 million KW, and the annual power generation capacity will exceed 390 billion kWh。 Among them, the installed capacity of offshore wind power has reached 30 million KW, and wind power has become an important power source for the power system.
However, with the increasing popularity of wind power generation and the growth of the working hours of existing units, the number of accidents is increasing, and each accident has caused a very serious risk of economic losses, ranging from the inability of equipment to be completely scrapped or even threatening the safety of personnel. Fire risks in the wind power industry are gradually being exposed to the public eye.
On March 14, 2021, the No. 26 wind turbine of Gongzhuling Wind Farm, a subsidiary of Inner Mongolia Energy Power Generation Investment Group Co., Ltd., caught fire during operation, and the engine room burned down. The cause of the fire was initially judged to be caused by the failure of the frequency converter. The accident caused damage to the converter of this wind turbine, resulting in burndown of the engine compartment of the 26th fan. It is understood that the installed capacity of Gongzhuling Wind Farm is 49.5MW, and a total of 33 single-unit capacity 1.5MW wind turbines have been installed. The wind farm was officially put into operation on November 23, 2009, and due to the long operating life, the unit failure rate is relatively large.
In addition, the wind turbine equipment is generally located in the remote wilderness, high from the ground position (the general tower height is 70 to 160 meters), the use of automatic unattended control system, and far from the rescue center, once a fire occurs, often can only be allowed to burn, and so that the combustion process is completely ended After the safety risk is minimized, the personnel can climb the tower to check the accident situation, which will cause huge losses to the power grid and the owner.
According to the long-term experimental research of He'an Dun Fire Protection, the high-burning engine room cannot be extinguished with traditional fire extinguishing devices, and it needs to be extinguished by a built-in intelligent fire extinguishing system. If a fire suppression system is missing, any fire in the cabin is likely to result in significant damage. The purpose of installing fire detection and extinguishing systems is to minimize losses, reduce maintenance costs, and shorten post-disaster downtime, while investigating the cause of the fire and being able to repair damaged parts. In view of this fire fighting scenario, Hubei and Andun independently developed a new pulse-suspended dry powder fire extinguishing device for wind power for one year when they consumed it, which is the fastest and most efficient automatic fire extinguishing system on the market, and is also the fundamental reason for wind power users to choose Andun.
At present, the product has been widely used in wind power scenarios, and its products have obvious advantages over similar products in terms of price and performance. At the same time, the pulse-type dry powder fire extinguishing device produced by the company has created the configuration and experience of 4 traditional fire extinguishing devices at the price of 2 products, which ensures the safety of the wind turbine cabin in a large and all-round way.
