Wind Generation Applications for the Cement Industry

Wind generation is the fastest growing power source over the past decade and this growth is forecasted to continue. The latest wind turbines have robust designs for reliable performance and increased energy capture, as well as sophisticated control systems that support electric system requirements and enable cost-effective operation. While the majority of wind plants are being connected to the utility transmission grid, applications are growing among industrial users. Within the industrial segment, cement is a leader in promoting emission reductions and generating power through cleaner technology. However, the integration of conventional wind plants into industrial systems presents challenges to both operation and security, including: (1) Tripping due to transmission system faults (2) Voltage fluctuation under varying wind conditions (3) Inability to control active power production (4) Lack of reactive power control and voltage regulation in the absence of wind New wind turbine generator and wind plant technologies have substantially improved system performance. This paper mainly focuses on the requirements of cement plants, and the ability of the latest wind turbine technology to meet those requirements. The paper illustrates the performance of a wind plant integrated with a cement plant. A short discussion of the economic trade-offs and decisions surrounding industrial self-generation with wind is provided as well.
