Wind Power Systems

Jiangsu is one of the most prosperous provinces in China with the highest population density but a shortage of fossil fuel. However, wind energy is recognized as a sustainable resource which is abundant in Jiangsu Province. Even so, the fluctuation of wind power, offshore and non-grid-connected wind power systems are required to manage this fluctuation. In addition, hydrogen production using wind power is a new idea to increase the contribution of wind power. According to the current situation of Jiangsu Province and wind power technology in China, there are both advantages and disadvantages to the method of hydrogen production in using non-grid-connected offshore wind power.

Although mega-watt class onshore and offshore wind power systems are used to generate power due to their cost-effectiveness, small wind power systems are important for household usages. Researchers have focused on aerodynamic characteristics as a conceptual design from their previous studies on Archimedes spiral wind turbines. Here, we verified the design of a small wind turbine AWM-750D (100 W capacity) via both numerical simulation and experimentation. We used commercial code ANSYS CFX for numerical simulation and compared turbulence models and surface roughness for determining the performance. To obtain reliable and robust blades, we analyzed the effective manufacturing method with Moldflow. Through a test with an open-suction type atmospheric boundary layer wind tunnel, we varied wind speed from 4.0 m/s to the rated value of 12.5 m/s and obtained 106 W, equivalent to a power coefficient of 0.205. In addition, we compared the numerical and experimental power vs. rotational speed and found the former is 6.5% lower than the latter. In this study, we proved that numerical simulations can act as design verification methods to predict wind turbine performances and reliable manufacturing. Through our research, we provided the prototype of a small wind turbine with 100 W to act as an efficient electric power supplier for households and also the stable manufacturing process for complex spiral blades using injection molding.

With the rapid rise of the marine industry, it is urgent need to develop the existing marine equipments. In order to meet the development of offshore wind power market and the construction of large-scale bridge over sea, marine machinery is melting towards large-scale, science, profession, intelligence, and multi-function. The study and development of the multifunction jack-up platform has a wide prospect, which integrating with piling, clear base, leveling, lifting, wind power installation, setting and providing life support for maritime and engineering. This article introduces our research status of existing multi-platform, illuminates the trends and application prospects, and puts forward a new multi-function jack-up platform for reference.
