Abstract

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
