Technical analysis of five major causes of investment in large wind turbines (4)

5. Technical analysis to expand the causes of difficulties

The larger scale development of wind turbines is the only effective way and means to achieve high efficiency, low price, simple, convenient design, production, installation, application, and stable operation, and to expand to greater capacity, higher efficiency, and stronger applicability. It is expected that it is also the driving force behind supporting and promoting the large-scale development of the wind power industry. However, from the above analysis of the overall shape and structure of the existing large-scale wind turbines, it can be seen that the efforts to achieve the above-mentioned many functions and capabilities are unlikely to have more room for development. Because in the process of overcoming one of the defects, the other related issues will form mutual constraints and it will be difficult to achieve the best of both worlds. For example, further efforts to amplify the design space of its blade will lead to higher occurrences of weight, cost, and failure rate. And the improvement efforts of some functional defects (such as setting up large multi-generator systems at high altitudes) will never be realized.

6. Conclusion

Obviously, on the basis of the small-scale horizontal-shaft three-bladed wind turbines, the shape and performance of the existing large-scale wind power generated by the gradual enlargement of the design specifications will produce many of the above-listed wind turbines that are not available on small wind turbines. Performance defects, structural problems, and application difficulties.

Being able to objectively, timely, comprehensively, and clearly understand the current technological development status of existing large-scale wind power equipment can provide expected beneficial tips and references for investment decisions. At the same time, it also constitutes the most original thinking power and foundation for exploring outstanding innovative solutions that are more suitable for the characteristics of large wind turbines.

It is to be pleased that after a long period of hard work and improvement, a large number of new large-scale wind turbine technology designs have emerged. They will solve the above-mentioned problems in an all-round way, and the larger the design scale, the more kilowatts per unit. The lower the cost, the higher the overall trend of development trends, which can form a variety of ambitious design and scale construction, and can be the application of the best models in different application conditions, which is expected to make wind power on-grid tariff lower than Or it is significantly lower than coal power (in the case of different wind conditions and unit construction scale).
