High-reliability products have created many annual full-time "model workers" wind farms

Recently, the "2023 National Trouble-free Wind Farm Management Achievement List" selected by the Operation and Maintenance Branch of China Electric Power Technology Market Association was released.52 wind farms supplied by Sany Renewable Energy made the list, doubling the number from last year. In terms of the annual availability of wind turbines and the annual trouble-free operation time, Sany Renewable Energy ranks among the best.

Statistics show that the average annual availability rate of the wind farm units installed by Sany Renewable Energy is more than 99.8%, and the utilization rate of 27 wind farm units has reached more than 99.9%, which is higher than the average level of the wind farms on the list. In addition, there are 6 wind farms with Sany Renewable Energy fans operating 365 days a year without failure, and the unit utilization rate is 100%, which can be called the annual full-time "model worker" wind farm; The maximum utilization hours of the wind farm owned by Sany Renewable Energy Unit reached 3,882 hours.

The results of trouble-free wind farm management are:Wind power equipmentThe comprehensive embodiment of reliability, quality and efficiency of operation and inspection management, and safety production operation and management level is the result of the coordinated efforts and tacit cooperation between the upstream and downstream of the industrial chain, and has a benchmarking role in the high-quality and sustainable development of China's wind power industry.

With 100% unit availability and 365 days of trouble-free operation, how did Sany Renewable Energy's annual full-time "model worker" wind farm come into being?

Digital intelligence builds reliable genes

Flowers cannot bloom in poor soil, and highly reliable wind turbines cannot be born in backward production processes and manufacturing lines。 Since its establishment, Sany Renewable Energy has promoted the intelligent manufacturing of wind power equipment with the strength of the whole company, and controlled the product quality from the source with digital intelligence. Through the use of independent research and development, the industry's first series of intelligent machinery and equipment, the "leapfrog" upgrade of the automation, integration and intelligence of the whole machine manufacturing process is realized, the quality deviation caused by manual operation is avoided, and the product quality consistency is ensured.

At the same time, relying on the combination of digital twin technology, human-machine interconnection technology, automation technology and 5G communication technology, Sany Renewable Energy has built the "digital brain" of the intelligent manufacturing factory, realizing the visualization of the whole cycle of the production process, the whole process of material control online, and the refined management of key production data, so as to comprehensively control the production process and ensure product quality.

All-round test to train "strong body"

In order to ensure the reliability of the unit during its 20-year service life, Sany Renewable Energy has built four wind power test bases, established a full-process and multi-level testing and verification system covering wind turbine materials, components, subsystems, complete units and batch fleets, and relied on strict test standards to move the wind farm verification forward and fully demonstrate the reliability of components and the whole machine. Only qualified parts that have passed the test levels and successfully "fought monsters and upgraded" are eligible to be installed on the wind turbine and go to a windy place.

Of course, a comprehensive test to ensure the reliability of the unit is only the starting point. Sany Renewable Energy insists on "speaking with data",The data obtained from the experiment feeds back the design, explores the unknown technical boundaries, and unites the upstream and downstream of the industrial chain to promote product optimization and innovation。 It is the first in the industry to promote the mass application of new technologies such as blade pultrusion glass plate technology and double TRB (single row tapered roller bearing) spindle system, so that the rigidity and strength of components can be improved simultaneously, and the overall performance and power generation efficiency of the wind turbine will be enhanced.

Smart O&M is more important than prevention

Relying on the smart wind farm operation and maintenance system for preventive maintenance to achieve prevention before problems occur is also one of the secret magic weapons for Sany Renewable Energy units to maintain a low failure rate.

With the support of the data analysis platform of the smart wind farm system, Sany Renewable Energy relies on the wind turbine diagnosis and fault early warning model to carry out real-time health diagnosis of heavy components of wind turbines, realize early warning of wind turbine failures or component failures, deploy maintenance strategies and resources in advance, and reduce the duration and frequency of unplanned shutdowns and reduce power generation losses through preventive operation and maintenance measures of "prediction, early warning, pre-inspection, and pre-repair".

The wind does not stop, and the pace does not stop. As a member of China's wind power industry, Sany Renewable Energy will continue to empower the R&D and manufacturing of units with new quality productivity, build highly reliable and highly adaptable intelligent wind turbines, and promote the "unmanned" and intelligent operation and maintenance of wind farms, so that every wisp of wind can truly be "used to the fullest".
