摘要
通过对株洲电网2000—2008年电力负荷数据进行分析,包括用电结构、典型日负荷特性、月负荷特性、年负荷特性,发现空调负荷和大型工业负荷对株洲电网负荷特性的影响较大:空调负荷导致峰谷差加大,在峰谷电价的作用下,大型工业负荷起到了削峰填谷的作用。针对这2类负荷给系统运行带来的问题,提出了改善株洲电网负荷特性的建议。
Based on the power load data from 2000 to 2008 in the Zhuzhou region, an analysis is made on the characteristics including the power use structure and the typical characteristics of daily, monthly and yearly loads. It is found that the power load characteristics in the region is mainly subject to the power consumption of air-conditioners and large-scaled industrial consumption： the power load of air conditioners widens the load gap between peak and valley, while the industry load flattens the load curve because of the tariff difference between peak and valley. Related suggestions are proposed to address the problems that these two types of loads bring to the operation of the grid with a view to improving the load characteristics of the Zhuzhou power grid.
