摘要/Abstract

摘要： 首先分别建立了单位电能发电成本函数、单位电能输电成本函数和单位电能输煤成本函数;然后通过比较输煤输电2种输能方式在负荷中心获得单位电能的总成本,给出了较完整的输煤输电经济性分析模型;继而定量分析了煤炭运价、输电线路利用小时数、煤炭价格、煤炭热值和交流线路串补度等因素对输煤输电经济性比较的影响;最后针对中国主要煤炭基地和电力负荷中心进行了输煤输电经济性具体比较。研究表明,输煤输电的经济性比较受到多种因素影响,不能笼统地认为输电更经济或者输煤更经济;只有针对具体问题,统筹考虑各种因素,才能判定输煤输电的经济性。

Abstract: The functions of power generation cost, power transmission cost and coal transportation cost per unit power energy are established first in the paper. And then, based on the comparison of the total cost of unit power energy in load centers between coal transportation and power transmission, a comprehensive model for economic comparison between coal transportation and power transmission is proposed. In addition, the influences of coal transportation price, annual utilization hours, coal price, coal heat value, and series compensation degree on the economic comparison between coal transportation and power transmission are analyzed quantitatively. Finally, the economic comparison is also conducted for main coal bases and load centers in our country. The study concludes that since various factors may contribute to the economic comparison results, we cannot determine whether coal transportation or power transmission is more economical in a general way. Actually only through comprehensive analysis on the practical situation can we decide which one is more economical.

Key words: coal transportation, power transmission, influencing factor, economic comparison
