this year, the installed capacity of wind power in China has maintained an increasing trend from the definition. At the end of the year, the country's first "bidding" standard rules for offshore wind power and onshore wind power were officially released, The Guangdong Provincial Energy Bureau officially issued the "Guangdong Province offshore wind power project competitive allocation measures (Trial)" and "Guangdong Province onshore wind power project competitive allocation measures (Trial)", which will be implemented from January 1, 2019 for a trial period of three years. Ningxia also immediately issued the "bidding" standard rules, becoming a pioneer in promoting "bidding". The "bidding" of wind power around the country has gradually begun, laying the foundation for officially entering the "bidding" era in 2019

The arrival of the bidding era puts forward higher requirements for equipment. Gao Wei, deputy chief engineer of Datang renewable energy testing and Research Institute Co., Ltd., said that the four development directions of wind power in the future are large-scale, intelligent, offshore and energy storage. This year, the growth of new onshore wind power projects in China slowed down. In contrast, the installed capacity of offshore wind power increased significantly. With the increasing demand for equipment in the market, the large-scale fan is still the trend in the future. According to the data of the national energy administration, China's wind power capacity increased by 12.6 GW in the first three quarters, an increase of 30% over the same period in 2017, and the total volume reached 176 GW

strong growth momentum of offshore wind power

against the background of the slowdown in the growth of new onshore wind power projects, China's offshore wind power installed capacity has grown rapidly in the past two years, and reached a total installed capacity of 3.1 GW at the end of August this year. In the past two years, the state has continuously strengthened the development of offshore wind power construction. The first offshore wind power industrial park in China, Fujian Three Gorges Offshore Wind Power International Industrial Park, is under construction. The park includes host plants, blade plants, and fan supporting plants. After reaching the production capacity, it will realize the localization, high-end, and large-scale of the main components of the offshore wind power machine. At present, various projects are under construction. According to Zhang Yuhao, deputy general manager of Fujian Three Gorges Offshore Wind Power Industrial Park, after the completion of the industrial park, it hopes to become an industrial alliance, strive to build the industrial park into a world-class Wind Power Industrial Park, and catch up and surpass in offshore wind power technology

in addition, the world's first international high-power offshore wind power test wind farm, Fujian Xinghua Bay offshore wind power phase I project, has been completed. The 14 installed typhoon turbines come from eight domestic and foreign mainstream machine manufacturers, including Goldwind technology, haizhuang wind power, Taiyuan Heavy Industry, Mingyang intelligent, Dongfang wind power, Shanghai Electric, Xiangdian wind power, and Ge. It is understood that the offshore wind turbines provided by domestic machine manufacturers have become the main force of the wind farm, After a period of trial operation, the results show that domestic machine manufacturers have made great achievements in supplying wind turbines. As of October 20, the annual power generation of the Three Gorges Fuqing Xinghua Bay prototype offshore test wind farm exceeded 100million kwh, exceeding the 2018 annual power generation index issued by the Three Gorges group, and achieving a new breakthrough in the operation efficiency and benefits of the wind farm

from the analysis of the types of wind turbines installed in the test wind farm, at present, the types used in China's offshore wind power projects are mainly 5-6 MW series. According to the data of the Three Gorges Fujian Fuqing Xinghua Bay offshore test wind farm, Mingyang intelligent myse5.5/7.0 MW units are eye-catching in the Three Gorges Fujian Fuqing Xinghua Bay offshore test wind farm

high power wind turbines have become the future development direction of offshore wind power. On December 19, Shanghai Electric's first 7-megawatt offshore wind turbine was officially loaded and shipped to the Sanchuan offshore wind power project at Putou wharf, Fujian Province. The Sanchuan offshore wind power project will install Shanghai Electric's 7-megawatt offshore wind turbine. This offshore wind farm has become the first offshore wind farm in China to use more than 6-megawatt offshore wind turbines on a large scale. Xiangdian wind energy is also building 7 X series models of offshore wind turbine platform. Goldwind Technology launched GW MW wind turbine in October this year, which is the largest offshore wind turbine with a single unit capacity in China, with a power of 8 MW

from this point of view, offshore wind power is bound to go to the far sea and deep sea, and further large-scale wind turbines are the future development trend. The use of large-capacity offshore units is required for the centralized and large-scale development of offshore wind farms. It will effectively reduce the cost of kwh of wind farms, improve the overall economy of the scale development and utilization of offshore wind farms, and create more value for investors

onshore wind power aims at 3-4 MW units

the large-scale fan is the embodiment of technological progress. Whether the large-scale MW products can be recognized by the market in the future is the technical accumulation and R & D strength of the machine manufacturers. At present, the first tier machine manufacturers such as Goldwind technology, vision energy and Mingyang intelligent are at the forefront of the industry in terms of large-scale wind turbines, and these enterprises are expected to take the lead in the upcoming bidding era

the advantage of large MW fan is that it can significantly reduce the number of machine sites and save land acquisition. Behind the launch of new high MW power grade wind turbines by machine manufacturers is the objective demand for large-scale wind turbines, such as the pressure of wind power cost reduction and land resource constraints

in recent years, however, the workbench is relatively large, and the electricity price on the wind power benchmark has been reduced rapidly, and the bidding mechanism has put pressure on the wind power electricity price

insiders believe that the large-scale wind turbine can effectively reduce the initial investment cost, which is specifically reflected in the reduction of land use area, the cost of wind farm supporting facilities and transportation and construction costs. At the same time, it can save machine sites, which has an obvious advantage of saving land resources. Especially in the context of the upcoming domestic wind power bidding and parity, the wind turbine solution has advantages

Guo Ziming, the pre-sales technical support engineer of Vestas China, gives the following prediction for the future new models. At present, the market share of large MW wind turbines is increasing, and it is expected that this trend will be particularly obvious in 2020. The main units launched in Europe and the United States will be concentrated on the 4-megawatt platform, and the main models launched in China and India in the Asia Pacific region are the 3-megawatt platform. With the implementation of the bidding mechanism in Europe, the Middle East and Africa, the wind turbines of 4-mw platform began to move slowly to 5-MW platform, and the development space of 2-MW in these regions has been very limited. From the perspective of Asia Pacific, most Chinese machine manufacturers have begun to launch 3-mW or even 4-mw wind turbines

the above prediction was confirmed at the international wind energy exhibition held in October this year, and Goldwind Technology launched gw 3 MW onshore medium and low wind speed units; The ultra-low kilowatt hour cost intelligent fan en-141/3.6 MW launched by vision energy is suitable for medium and high wind speed regions in northern China

this year, 4 MW wind turbines independently developed by many domestic machine manufacturers have been rolled out. Dongfang wind power and Mingyang intelligent also made new achievements in the field of 4 MW wind turbines. Mingyang intelligent has launched myse4.0 series of fans with a power of 4 MW, which can provide personalized solutions for the characteristics of wind resources in diverse land landforms; The 4-mw onshore direct drive wind turbine of dec-d has been completed and rolled off the production line. Recently, Yunda wind power also rolled off its self-developed 4 The first prototype of X MW platform

it is not difficult to see that in the next few years, domestic fan manufacturers will continue to promote the R & D and manufacturing of high-power fans and continue to catch up with and surpass the international advanced manufacturing level
