How do automation manufacturers map the "new course" of offshore wind power

since Denmark built the world's first offshore wind farm in 1991, the installed capacity of offshore wind power in Europe has been increasing, and the technical level has also been continuously improved. At present, it has been in a leading position among its global peers. Driven by policies related to the development of alternative energy and the response to climate change, domestic offshore wind power projects are also poised for development

tanfengjun, an electrical engineer in the Technology Department of Ruineng north wind power equipment Co., Ltd. (hereinafter referred to as Ruineng), believes that compared with traditional onshore wind power projects, offshore wind power projects have obvious advantages. Abundant offshore wind power resources, suitable for the operation of large-scale wind turbine; At the same time, the sea space is vast and the development potential is huge; In addition, due to the relatively developed economy and large power consumption in coastal areas, offshore wind power is easy to be consumed nearby without long-distance transmission. Tan Fengjun explained

with the increasing number of offshore wind farms, the location of the wind farm will most likely be in the far sea area that is more and more distant from the coast. Therefore, the reliability, safety, corrosion resistance and other factors of the fan become more important. Tan Fengjun said that as a supplier of wind power equipment, Ruineng company has increasingly heard the urgent needs of users for the reliability of wind turbines. Therefore, as users of automation products, our requirements for automation products are also based on meeting the reliability of fans as the first 2.3 interface and program control. At the same time, the application of pitch control system and state monitoring system in wind power projects will be more extensive. Tan Fengjun said

how can automation products meet the needs of offshore wind turbines

compared with onshore wind farms, offshore wind farms are more difficult to access, which directly leads to downtime and replacement and maintenance costs becoming more critical factors than the actual cost of spare parts. At the same time, because operators want to obtain greater capacity, the fan system has to develop to a larger specification. However, while obtaining greater capacity, operators have to bear the risk of greater loss of failure. Therefore, reliability has become an important index for the normal operation of fans

in order to enhance the reliability of fans, automation products must have the characteristics of corrosion prevention, salt spray prevention, moisture prevention and mold prevention. Tan Fengjun believes that this is the basic requirement of automation products applied in offshore wind power projects. At the same time, he also pointed out that in order to improve the reliability of automation products, the necessary redundant design is very important. One way is to improve the safety factor, and the other way is to backup some parts. After the parts fail, the backup parts can continue to operate instead of the original parts. This effectively reduces operational risks and maintenance costs. Tan Fengjun concluded

how to select the pitch control system

at the 2010 Beijing International Wind Energy Conference and exhibition, SSB showed its independently developed high-power pitch system, which will also be applied to the 3.6MW offshore wind turbine of Shanghai Electric. Tanfengjun believes that this is another upgrade of pitch control technology. Does this mean that electric pitch system will occupy a larger market share in offshore wind power projects

according to tanfengjun, at present, electric pitch system and hydraulic control system are applied in the fan manufacturing market. With the electric pitch control system, there will be no hydraulic oil leakage, so this system will not cause environmental pollution caused by the high-temperature hydraulic oil system, and its energy consumption or waste is also less than that of the hydraulic pitch control system. At the same time, the electric pitch control system is more energy-saving than the hydraulic pitch control system, because the hydraulic pitch control system requires the pump to run at all times to keep the system at a high oil temperature and be ready to let the blades start rotating at any time. But he also pointed out that the safety battery or capacitor in the electric pitch control system is its weakness, especially in the harsh environment at sea, how to keep the battery from corrosion is also crucial. Therefore, at present, there is no clear answer to which kind of pitch control system is better, which is called "tiger skin pattern". Users need to make decisions according to their actual needs

the application of condition monitoring system will be more common

it is understood that by 2020, China will build seven wind power bases, each with a power generation capacity of more than 10kW. Two of the bases are located in Inner Mongolia, so the fans will maintain stable operation in cold winter and dusty spring. In fact, there are countless such cases in the world. Therefore, more and more wind power operators generally believe that under harsh environmental conditions, wind turbines need more state monitoring. Because most of the fans are located in the environment with extremely strong wind speed and harsh environment, but as a 1-dimensional quantum material perfectly connected by a hexagonal structure, it has a high probability of failure

due to the increasing size of fan equipment, once it fails, operators will suffer huge economic losses and expensive maintenance costs; At the same time, the offshore wind turbine is not easy to access and the maintenance cost is high; In addition, most of the domestic fresh air farms are located in remote places with bad weather conditions, and the scale of the wind farms has also increased accordingly. These factors have promoted the development and maturity of the wind power industry condition monitoring system market. The condition monitoring system can indeed provide a reliable monitoring method for the safe operation of the fan, so that we can make a judgment in advance about some unsafe factors, which are usually controlled by computers. We are also actively responding to market demand. This year, some wind farms in Shandong have used condition monitoring systems. Tan Fengjun said

development trend of automation products in the wind power industry

the broad prospect of domestic offshore wind turbine applications has brought new development opportunities for wind turbine manufacturers, and models with good quality and rich operation experience will become the preferred models for owners. However, Tan Fengjun pointed out that the development of offshore wind power projects is still restricted by the problems of offshore power transmission, offshore anti-corrosion measures and the impact of typhoons, and the design ability of wind turbine manufacturers is still being tested. So how should automation manufacturers deal with it? Tan Fengjun said: automation products will be widely used in wind turbines. Safety is always the top priority of power system, so one of the important indicators to evaluate whether automation products are suitable for application in the wind power industry is safety performance; At the same time, the corrosion resistance, reliability and intelligent level of the automation system are also the primary considerations of the fan control system; Systematization, large-scale and networking of automation products are the basic requirements of wind turbines, which will also promote the continuous improvement of the performance of wind turbines

in onshore wind power projects, the development of large-scale wind turbines is an inevitable trend. According to tan Fengjun, with the reduction of IEC class I wind farm resources, IEC class II and IEC class III fans will have a better market prospect. At the same time, with the expansion of the scale of wind power, the labeling of wind power will be more and more strict, and the adaptability requirements of wind turbines to electricity will also be further improved. Then, the automation products applied in these fields are bound to have stronger reliability and stability
