浅议输煤与输电问题

Coal Transportation and Power Transmission

全面深入阐述了在我国一次能源资源地理分布很不均匀,与全国各地区的经济发展情况不匹配的国情下,输煤与输电何者更优的问题:输煤输电问题应根据国情在高层次上加以综合研究,电网已是综合运输体系中的组成部分,输煤输电不是零和关系而是相辅相成的,我国煤运紧张局面将长期存在,需发展远距离输电协助缓解,发达地区的环境容量不允许无限制增建煤电厂,大水电、大风电等能源的利用有赖于远距离输电,要通过建设坑口煤电基地扶植资源输出地区的发展。因此,国家应统筹协调,因地制宜,利用高新科技,输煤输电并举,使国家的运输系统达到全局最优化。

This paper looks into details of China＇s uneven geographical distribution of the primary energy, and the disparity of economic development among different regions, and deals with comparative advantages between coal transportation and power transmission. Both coal transportation and power transmission issues should be studied at a high level according to the country＇s basic conditions; and power grids should be regarded as an integral part of the comprehensive transportation system of the country; and the relationship between coal transportation and power transmission should be complementary rather than zero sum. The tension of coal transportation will remain in China in a long time, therefore it takes long distance power transmission to alleviate it. The environment capacity in the developed regions makes it impossible to add more coal- fired power plants, and utilization of large-scaled hydropower and wind power calls for long-distance power transmission. Considering all these conditions, the state should balance and coordinate all the players in the energy sector, and make policies based on the actual situations, and make full use of high technologies, and lay balanced stresses on coal transportation and power transmission in the hope to realize the overall optimization of the transportation system in the country.
