An investigation was conducted regarding the potential economic benefits associated with using a wind turbine to power a groundwater circulation well (GCW) at the former Nebraska Ordnance Plant Superfund site. The first phase of the investigation used a 10‐kilowatt‐rated grid inter‐tie wind turbine to partially offset the purchase of electricity from the utility company. The second phase consisted of the conversion of the grid inter‐tie system to an off‐grid system that stored energy using batteries. During the second phase, the GCW system was operated using either wind turbine power or utility power, and the other system components were operated using utility power. The study showed that a significant amount of power purchased from the utility company was used for nonessential purposes (other than operating the GCW pump and essential treatment components). One nonessential power consumer was the continuous heating of the equipment shelter for operator comfort during their 10‐minute visit every few days. Wind‐turbine reduction in utility power consumption was evaluated, and the operating time of a hypothetical system powered solely by the wind turbine was compared to the actual GCW operating time. This study indicates that retrofitting this GCW system did not economically offset power costs from a cheap, readily available grid system. Perhaps at a remote location with a more energy‐efficient design and operation and the inclusion of green power benefits (in some monetary amount), the wind turbine results will be more favorable. The study of a renewable energy application at the site highlighted opportunities for significant electrical energy savings regardless of the source of the electricity. © 2008 Wiley Periodicals, Inc. 相似文献

针对多年来一直争论的过网网损分摊公平性问题,从功率平衡角度阐述了过网网损的本质。然后从过网网损本质和电力市场的公平性原则出发,深入分析了现有应用于过网网损计算的平均网损系数法模型,在此基础上提出了一种新的模型,该模型采用转供网送出功率与全网网损率的乘积作为过网网损,在完成过网网损计算的同时自动将过网网损合理分摊至区域内各受电主体。该模型一方面能够反映转供网送出功率与过网网损之间的关系,符合过网网损本质属性;另一方面区域内各主体采取降低自身电网网损的措施,在降低自身电网过网网损分摊量的同时,也降低了过网网损,即该模型对降低过网网损具有明确积极的指导意义。 相似文献
