A Brief Discussion on the Current Status and Prospects of Wind Power Engineering
2021-08-13
With the advancement of urbanization, environmental challenges have become increasingly acute, and the supply of traditional fossil fuels such as coal is growing increasingly strained. As a low-cost power-generation sector, wind-power projects have garnered widespread attention across countries and regions worldwide, making wind power one of the most technologically mature, scalable, and commercially promising forms of new-energy generation. In China, abundant wind resources and rapid development in recent years have further underscored the importance of this sector. Meanwhile, the application of cutting-edge technologies in the manufacturing, control, and management of wind turbines has continued to evolve. This paper examines the current state of wind power in China, the challenges it faces, and its future development trends. Let us now explore the present status and prospects of wind-power engineering.
The development of wind power is of paramount importance for ensuring energy security, optimizing the energy mix, mitigating environmental pollution, and achieving sustainable development. Wind power projects currently represent a mature and economically viable renewable energy source.
1. Current Status of Wind Power Generation in China
China is one of the world’s richest countries in wind resources, with a history of wind utilization dating back to ancient times. It is among the leading nations in the global use of wind power; however, research and development in wind power generation only began relatively late. If the development and utilization rate of wind resources were to reach 60%, wind power alone could meet China’s current annual electricity demand.
2. Several Issues in Wind Power Generation
Wind resource surveys are unscientific and inaccurate, often lacking a systematic and evidence-based approach. The operation of wind turbines is a complex process that involves numerous technical and operational considerations. The effective wind speed range for wind power generation typically spans 3 to 25 meters per second. Consequently, site selection is of paramount importance in the development of wind farms.
On the other hand, China’s current wind resource distribution is relatively dispersed and of low quality, making it difficult to meet the demands of rapid wind power development, thus creating an urgent need for more refined segmentation. Moreover, procuring equipment from overseas entails substantial costs. Specifically, turbine siting within a wind farm must be evaluated based on several factors, including wind resource assessment parameters, macro-site selection, and micro-site selection. The fundamental requirements for wind farm site selection are abundant energy resources and stable wind direction.
The foregoing discussion has provided a brief overview of the current status and future prospects of wind power engineering. With the state’s reform of the approval system for wind power projects and the successive introduction of a series of laws, regulations, and fiscal and tax incentives to support the new-energy industry, both the wind power sector and related research institutions should seize this favorable opportunity presented by the national policy of promoting clean energy development, accelerate the growth of the wind power industry, and ensure that the utilization of wind energy makes a substantial contribution to China’s energy structure adjustment, environmental protection efforts, and reduction of dependence on imported energy.
