摘　　要：以福建省某茶区为例,通过曲线分析法绘制该地区近几年的年、月、日的电力负荷曲线,根据负荷曲线的变化规律来解释当地的电力负荷特性。分析表明,该地区具有明显的季节性用电负荷特征。在茶季因电网的容量不足,尖峰负荷对电网冲击很大,容易造成电网故障。将车载移动式变电站接入该茶区某典型110kV变电站,结果分析表明,车载移动式变电站的接入增大了电网容量,起到了有效的缓解电网尖峰负荷的作用,为今后应对季节性负荷等相关问题提供重要的参考依据。Taking a tea region in Fujian province as an example.Draw the power load curve of the region by analysis,According to the variation of the road curve the local power characteristics.Analysis shows that the region has significant seasonal electricity in the tea season.Due to the lack of the grid capacity,the peak load has a big impact on the grid,and it is likely to cause power failures.Connecting the mobile substation to the110kV substation,the results showed that the mobile substation increases the capacity of the grid,and play an important role to ease the peak load power.Providing an important reference to deal with the related issues,such as seasonal load.
