三次产业用电特性及负荷结构研究

Research on Chararteristics and Structure of Electricity Loads for Three Industries

全社会用电负荷曲线由三次产业用电负荷曲线及居民生活用电负荷曲线组成。通过大用户负荷曲线叠加,测算了典型行业及居民生活的用电负荷曲线,研究了用电特性及其发展规律,并以类似方法估算了三次产业的最大用电负荷,揭示了负荷结构与产业结构的关系。结果表明,四川地区三次产业典型行业均具有明显的季节特征;第一产业用电负荷比重极小,第二产业用电负荷比重较大,第三产业用电负荷迅速发展,居民生活质量不断改善。

Power consumption curve of the whole society is composed of three industries ′electricity load curve and residential e-lectricity load curve .Through the superposition of electricity load curve of large customers , the electricity load curve of typical trade and residents is calculated .The characteristics of electricity loads and its law of development are studied .The maximum electricity load of three industries is also evaluated in a similar way , and the relationship between load structure and industrial structure is investigated .The results show that the electricity load of the typical trade in three industries presents obvious sea -sonal characteristics in Sichuan area .The electricity load proportion of primary industry is relatively small , and the load pro-portion of second industry is relatively large .Particularly, the electricity load of third industry develops rapidly , and the quali-ty of residential life is being improved continuously .
