3.3.1 电力系统现状

从发电角度来看,尼泊尔可被称为“水电国家”。作为一个没有石油储量的内陆国家,现实情况是,在狭窄宽度约100 km 的范围内,海拔高度从8840 m 至不到100 m。冰和融雪水不断地为河流提供可靠的水源。但是,水电的开发很有限。理论上的水电蕴藏量有83290 MW,但是到现在为止只开发了554 MW。尼泊尔有四大河流流域:最西部地区的马哈卡利一格尔纳利流域,西部地区的根德格流域,中部和东部地区的撒普特一科西流域,以及南部的河流流域。把尼泊尔的水电作为该地区的高峰用电是非常划算的。技术上可行的水电蕴藏量有48 000MW,蓄水工程可发电约52%大约23 000 MW 是水电。尼泊尔的国内电力市场,每年高峰电力需求增长8%,到2010 年容量需求达到857 MW,预计到2020 年将达到1 820 MW。但系统负荷曲线峰值突出,约是基荷的2.5 倍。为满足电力需求建设光伏发电项目是有必要的。经勘测光伏发电总装机量为10MW 和当地电网匹配,本项目装机容量不会对电网的安全运行产生影响。

3.3.1 Current Situation of Power System

From the perspective of electric-power generation, Nepal can be called “hydroelectric power country”. As an inland country with no petroleum reserves, the fact is, in the narrow width of the range of about 100 km, the altitude varies from 8840m to less than 100m. Ice and snow melt water continuously providing reliable supply for the rivers. However, the development of hydroelectric power is limited. The hydroelectric power reservation in theory is 83290 MW, but so far only 554 MW has been developed. Nepal has four major river basins: Mahathir马哈卡利Mahakali一格尔纳利Karnali river basin in the most western region, 根德格Gandak river basin in the west,撒普特科西Sapta Kosi river basin in the central and eastern part, and the river basin in the south part. It is quite cost-effective to utilize the hydroelectric power as power resource during peak hours in the region. The technically feasible hydropower reserves are 48 000MW,water storage projects could generate about 52%, and of which 23000MW is hydropower.On the domestic electricity market in Nepal, the peak-hour power demand increased by 8% every year, so far until 2010 the capacity demand has reached 857MW, and it is estimated that the demand will grow to 1820MW.But the curve peak of system load is prominent, it is about 2.5 times as much as that of the base load. It is necessary to build photovoltaic power projects to meet the demands of electric power. After a survey, the general capacity of photovoltaic power generation is10MW, which matches the local power grid, the installed capacity of this project will not affect the safe operation of the grid.
