“电力丝路”送来“能源大礼”

2017-08-23 08:38:55   中国青年网

特高压“一交一直”两项工程在河南的混联运行,对于形成“三交一直”特高压骨干网架,实现全省“内增外引、开放发展”的能源发展战略具有重要意义。截至目前,我省通过天中直流工程吸收新疆电力873亿千瓦时,相当于减少煤炭消耗2400万吨,减排二氧化碳6600万吨,减排二氧化硫等污染物61.6万吨。

郑州航空港经济综合实验区作为中原经济区的核心增长极,目前已有1000多家企业入驻,能源消费量巨大。为了发挥清洁能源高效发展的示范效应,园区内禁止燃煤。“天中直流工程投运正当其时,消除了我们对能源供应的担忧,未来园区所需八成以上电能将依赖该工程输送。”航空港实验区管委会主任张延明说。

如今,在充足可靠电力的护航之下,航空港实验区已发展成为驱动全省经济增长的“新引擎”。2016年,园区完成固定资产投资626亿元,完成进出口总额482亿元;全年共制造手机2.58亿部,约占全球手机供货量的七分之一。借着产业发展的“东风”,更多的河南百姓实现家门口就业。

除了提供更加充足的电力保障,“一交一直”特高压工程充分体现了“电从远方来、来的是清洁电”的样板作用。以天中直流工程为例,2016年,我省通过该工程吸收的疆电为301亿千瓦时,超过全省吸收外电总量的四分之三,相当于六座100万千瓦装机的电厂一年的发电量,年减少直接煤炭消耗约900万吨。

历史的突破

一直以来,国网河南电力始终树立“特高压建设无小事”的理念,倾力而为。早在1000千伏晋东南—南阳—荆门特高压交流试验示范工程建设中,该公司就启动实施省、市、县、乡、村“五级联动”机制,有力地推动了各项工作开展,并成为国家电网公司特高压建设典型经验。

在1000千伏南阳开关站施工中,国网河南电力创造了“六个率先”:率先完成高抗安装;率先通过试验,具备受电条件;率先完成HGIS新型高压开关设备安装,并顺利通过现场交流耐压试验等。在该站扩建工程中,省电力公司全面贯彻国家电网公司全寿命周期建设理念、“两型一化”和“两型三新”工程建设原则,在国内首次采用新材料、新工艺,使塔重减轻12%—24%,造价降低6%—12%,既提高了线路铁塔的刚性和强度,又节省钢材,降低了维护成本。

在天中直流工程建设中,国网河南电力首次承担特高压线路建设管理任务,成为该工程河南境内147.5千米线路的项目管理单位;首次实行特高压线路通道清理属地化管理,建立了通道清理新模式;新建的±800千伏中州换流站占地面积、输送容量均创全省新纪录。

在±1100千伏昌吉—古泉特高压直流输电线路工程建设中,我省创造了多项国内、省内电网建设新纪录:工程采用了目前世界上最大承载力达84吨的瓷瓶,可承载导线重量更大、运行更稳定;耐张塔瓷瓶串最大长度达到28米,创造了新的世界纪录;在国内首次开展碳纤维复合导线试验段展放,展放长度为400米,为碳纤维导线科技项目研究提供了可靠数据支撑;N8419号塔铁为河南第一电力高塔,全高151.5米。与此同时,昌吉—古泉工程跨越南阳—荆门工程施工成功放线,标志着世界电压等级最高的直流线路首次跨越电压等级最高的交流线路顺利完成施工。

此外,在晋北—南京、上海庙—临沂特高压工程建设中,国网河南电力与山东省电力公司积极沟通、主动协调,开创性地采取了交叉建管新模式,有力地推动了工程快速进展。因两项工程在河南和山东交界处线路走向大致相同,河南、山东建管标段中均有一段位于对方境内,双方本着互帮互助的原则协商,采取属地管理方式进行通道清理,即山东建管标段位于河南境内部分由河南省电力公司负责,反之亦然,以此加快了建设进度,受到国家电网公司的充分肯定。
