贵州典型行业及用户负荷特性分析

Analysis on Power Load Characteristics of Guizhou Representative Consumers

[目的]贵州经济社会发展呈腾飞之势。为了全力满足贵州经济社会发展的用电需要,贵州电力系统需要加快发展。负荷特性的分析是电力市场分析的一个重要方面,把握负荷特性及其变化趋势是电力规划、生产、运行工作的重要基础。[方法]从贵州产业结构中的第一、第二、第三产业和城乡居民生活用电展开了典型行业及用户的负荷特性分析。[结果]文章基于统计数据给出了典型行业及用户的年负荷曲线和典型日负荷曲线,并对其特点和变化趋势进行了分析。[结论]由于各行业的自身用电特点的不同,年负荷随月份变化的规律以及冬季典型日和夏季典型日出现高峰的时间点各呈现出不同的变化规律。分析了解贵州各个主要行业的负荷特征,为负荷预测,乃至贵州电力发展规划工作的科学性和准确性提供了坚实的基础。

[Introduction]Economic and social development of Guizhou province is taking off.In order to fully meet the power demand,Guizhou power system needs to accelerate its development.[Method]Analysis of load characteristics was an important aspect of power market analysis.The load characteristics and changing trends was an important basis for power planning,production and operation.This paper analyzed the load characteristics of typical industries and users from the first,second and third industries of Guizhou industrial structure and the domestic electricity consumption of urban and rural residents.[Result]As a result,this paper demonstrates the annual and daily load curves of typical industries and users based on the analysis of statistical data.Their characteristics and trends are analyzed.[Conclusion]Due to the different characteristics of power consumption in different consumers,the annual load varies with months,and the peak time points of typical days in winter and summer show different rules.This work provides a solid foundation for load forecasting and even for the scientific and accurate planning of Guizhou power development.
