深圳市电力负荷特性分析

以深圳市电网2003～2006年的电力负荷统计数据(包括日负荷和年负荷等)为依据,得出电力负荷特性的现状及变化趋势(深圳电网总的变化趋势是:最大负荷、最大峰谷差和年负荷率都在逐年增加,年平均负荷率变化不大),详细地分析了其形成原因,得出了影响深圳负荷及负荷特性变化的主要因素(产业结构的调整、居民收入及消费水平的提高及消费观念的变化、需求侧管理的影响、气温的影响、电力供应的影响)。

The Analysis of Power Load Characteristics in Shenzhen

Based on the statistical data of power load for Shenzhen power grid in 2003~2006(including daily load rate and annual load,etc.),power load characteristics and changing trend(the general changing trend of Shenzhen power grid is: maximum load,maximum peak-to-valley difference and annual load rate are all increasing year after year,but annual average load rate changes very little)can be concluded. After analyzing the reasons of them,the main factors of the change of the power load and load characteristics of Shenzhen power grid(adjustment of industrial struc-ture,improvement of residents' income and consumption level,changes of consumption concept,effects of consumer's management,air temperature and power supply)are also given.
