With the digitization process continuously integrated into industries and manufacturing industries, the industrial structure will be reshaped as the industry upgrades, and digitization has become a 'cutting tool' in the development of wind power.
Digital understanding can have many dimensions. Digitalization in different industries has its own different value directions. Regarding the digitization process of Xinjiang Goldwind Science and Technology Co., Ltd. (hereinafter referred to as 'Golden Wind Technology'), Chairman Wu Gang once said, 'By digitizing Driven by innovation, it can connect some of the originally fragmented plates together to form a complete system, which can control the occurrence, development and change process through the system model.
This is also Goldwind's understanding of the digitalization of the wind power industry. Wind farm investment has the characteristics of long financing cycle and large investment scale. How to control the investment cost to the lowest point is the key to wind farm investment, and also an important component of wind power investment risk analysis. Part of the conventional risk investment analysis method, combining previous wind measurement data, mapping topographic maps, land properties, etc., to carry out risk control and benefit assessment before construction of wind farms. However, the current wind resource assessment software at home and abroad has obvious deficiencies: The complex terrain captures distortion, the fluid model is too simplified, the deviation of the wake calculation results is large, and the algorithm barriers, etc., cause current wind farms in the complex terrain wind resource assessment there is a certain deviation: flat terrain wake impact prediction is not enough, the unit generating power deviation At the same time, conventional evaluation tools are difficult to adapt to market changes in economic evaluation, and there are also shortfalls in revenue evaluation. In response to these outstanding issues, Goldwind’s scientific and technological resources start with basic theories, deeply understand the application scenarios, and conduct comprehensive innovation research. Development work.
In 2017, Goldwind Science and Technology Resource Center developed a platform-level product dedicated to early stage investment in wind farm investment. GoldFarm. GoldFarm dynamically planned the wind farm investment, designed the financial profitability sector and connected them dynamically to optimize the wind farm. Pre-investment to help users get the most profitable solutions.

Since the beginning of the 2014 exploration period, from the disturbance temperature in meteorology to the correction of the Navier-Stokes equations in fluid dynamics, Goldwind has performed accurate wind field wind profiles, unstructured grids, thermal stability, and three-dimensional forest cover In-depth study of the layer model; in 2016, Goldwind tried to use the meteorological environment coupled fluid technology to develop GoldFOAM, the refined simulation technology of Goldwind's own property rights; in 2017, it also joined many famous experts at home and abroad, combined with the innovative development of artificial intelligence algorithms. The large eddy simulation Gold LES with property rights, the wind resources and accurate wake simulation simulation, the wind farm program arrangement, unit selection.
At the same time, combined with the thinking of big data, Goldwind uses thousands of existing PB-level terrain databases, thousands of wind tower data, and PB mesoscale meteorological data to serve Goldwind's digital products. With these data, GoldFarm is trained in actual combat, cultivating the platform's sensitivity to various terrains, and providing more accurate fluid models for complex terrain.
Based on these continuous iterations, Goldwind has also been focusing on the integration and application of mature technologies. UAVs, GIS technology, and WRF+CFD coupling technology have been incorporated in GoldFarm to quickly acquire three-dimensional geographic information data and identify high precision. Simulation calculation data, quickly form a road design program, identify risk points, automatically optimize the layout, reduce schedules, reduce costs, optimize revenue solutions, and significantly increase project economics.
GoldFarm Digital Wind Farm platform GoldFarm has completed more than 20 digital wind farms including Guodian Investment, Huaneng Power, Beikong Power, Datang, etc. since the release of 2017 Beijing International Wind Energy Conference & Exhibition (CWP2017). Planning and design work, the results have been unanimously approved by customers and design institutes.

In terms of digital experience, based on the more realistic wind farm digital construction, customers can use this experience to conduct government and industry reports and technology demonstrations. To meet this extreme demand, Goldwind adopts international advanced industrial grade unmanned people. Machine, equipped with a camera with better resolution for wind farm shooting, to get a more detailed digital experience, and at the same time develop 3D modeling algorithm to generate a physical 3D model with ultra high 10cm resolution, combined with VR, AR technology, restore The actual scene of real wind farms is different from 2D maps in the display of digital wind turbines. It can create a perfect somatosensory environment. Take a project in the south as an example. In the project development stage, the platform is based on high-precision input of geographic information data to support customers to report digitalization to the government. ,Science and technology of wind farms. 'What you see is real', showing the dynamic process of the road path, simulating the operation status of the wind turbine, etc. Really restoring the situation of the wind farm after completion, assisting the client in the review and reporting, and accelerating the decision-making speed.
In terms of environmental friendliness, GoldFarm relies on digital means to provide customers with the optimal wind environment-friendly solutions to help customers create the best environment-friendly projects. Take the Southern project as an example. In the forest development process, customers need to get the government In the approval process, the government has very high requirements for the environmental impact. GoldFarm simulated and optimized the amount of tree felling, road filling, and excavation in the design stage, avoiding precious tree species, etc. The final solution is more environmentally friendly under the premise of guaranteed income. Help clients to improve their customers' image through environmental protection requirements.
For wind turbine unit selection, the advantages of GoldFarm are reflected in its sophisticated simulation calculations for complex terrain, customized wind farm design, and the ability to compare multiple projects. Take a project in Hunan as an example. In the early stages, the customer did not have a topographic map. The general resources, the yield is not optimistic, the initial investment decision is not up to standard, and it is facing the situation of abandonment. Based on these conditions, Goldwind conducted a rapid drone survey, the optimal unit selection, the optimal design cost, and finally satisfied the customer. The demand for yield. While increasing the power generation by 2.3%, the project budget decreased by 2%, while ensuring the project capacity and avoiding unnecessary risk points. The whole chain of wind farms was realized in digitized form and it took only 20 days to complete the planning and design. Programme, work efficiency increased several times.
In terms of precision engineering design, GoldFarm is committed to reducing engineering costs, providing optimal road design, designing the shortest route, and optimizing project costs. Taking a project in Qinghai as an example, the project area is about 200 square kilometers, the project cost is high, and the customer is in urgent need. We hope to optimize engineering costs. GoldFarm integrates many years of experience in engineering design modules, using 10cm topographic maps as the underlying data, relying on high-precision survey data from UAVs, and combining research and development of refined CFD algorithms, GIS, and big data technologies, via the GoldFarm platform. Accurate avoidance of risk areas for program optimization, automatic design of multiple sets of road route programs, more accurate generation of optimal design plans, time reduction of 50% to 80%, and ultimately achieving optimal economic results, cost optimization of about 20%.
