塔中沙漠公路零碳示范工程案例研究

Research on the case of zero carbon demonstrate project in Tazhong desert highway

塔中沙漠公路沿线的植物需要通过深井泵抽取地下水来灌溉。植物生长用水需求的增加和地下水位的下降,导致用电负荷增加。而原有的柴油发电机已经老化,运维费用高昂且排放了大量的CO_(2)。为了满足灌溉用电需求和实现电力清洁替代,通过对比外部电网供电、更新柴油发电机供电、光伏+柴发供电、光伏+储能+应急柴发供电等4种供电方案,论证太阳能电池、光伏板规格、阵列运行方式,以及比选2种储能方案,最后确定了86座柴油发电机组的清洁替代方案。此工程每年将减少柴油消耗1 082 t,减排CO_(2)约3 410 t,还荣获了“2022年央企十大超级工程”称号。

The plant along Tazhong desert highway needs to be irrigated by extracting groundwater via deep well pump.The increase in water demand for plant growth and the decrease of groundwater level lead to the increase of electricity load.What's more,the original diesel generators are aging and it isn't only expensive to operate and maintain,but also emits large amounts of CO_(2).In order to meet the demand of irrigation electricity and realize clean substitution to electricity,compared with the four power supply schemes containing external power supply,updated diesel generator supply,photovoltaic+diesel generator supply,photovoltaic+energy storage+emergency diesel power supply,the solar cells,photovoltaic panel specifications and array operation modes are demonstrated,and two energy storage schemes are selected.Finally,the scheme of clean substitution including 86 diesel generating units is determined.This project will reduce diesel consumption by 1082 t per year and reduce CO_(2)emissions by about 3410 t.It is also awarded the"Top Ten Super projects of Central Enterprises in 2022".
