全球智能电网“脚本”之中国篇 [复制链接]

1#

中国智能电网市场有多大?Zpryme研究公司预测从2011年至2015年市场规模将从223亿美元增长至614亿美元,其中最大的份额将落在输电与配电板块。中国或将在新能源领域称冠,特别是风电领域。世界银行资助的一项最新研究表明中国正成为电动汽车革新的重要试验平台。至于智能电表,甚至有报告称至2020年,中国的智能电表安装基础将达2.5亿只。

但中国在其他方面也有着不容忽视的问题:拥有13亿人口及能源使用量巨大的制造行业,使中国成为世界第一能耗大国,几乎占据了世界能源相关的温室气体排放量的1/5——《纽约时报》。

中国由正负两方面原因引出的智能电网需求已吸引了投资者与厂商的广泛兴趣。仅就过去几个月的情况就可见一斑:

·Facebook与Groupon的幕后推手——风险投资公司Accel Partners计划对两项基金增资10亿美元,一项用于前期投资,一项用于后期商业机会;
·霍尼韦尔将开发实施中国首个需求响应试点项目,并开展商业楼宇能源管理的可行性研究;
·杜克能源与中国的新奥集团将合作开发中国与美国建设智能城市所需的相关技术;
·国网公司、中国科学院及通用电气将在制定中国坚强智能电网相关标准方面展开合作。

以上所列仅为沧海一粟,只是说明中国现在或不久的将来会在智能电网发展空间及商业机会方面扮演重要角色。



中国智能电网项目掠影

以下所列示的只是一小部分中国目前正在实施的智能电网相关项目与计划:
·输电升级。杜克大学智能电网研究院一份报告提到了中国在高压输电等方面的革新技术。2月,国网公司宁东山东660 kV高压直流输电工程投运,这是世界上首条660 kV直流输电线路。此项工程的参与者阿尔斯通近期在上海设立的研发与测试中心开幕,以加强其在特高压交流输电(UHVAC)与特高压直流输电(UHVDC)设备与能源管理方面的力量。阿尔斯通希望帮助中国在2020年实现1,200 kV交流输电与1,100 kV直流输电,目标是完成3条主要输电线路建设,每条线路拥有20 GW的传输能力。

·风电发展。上文所述之输电升级速度尚不足以支撑中国的风电产业,中国风力发电世界第一位的排名有下滑趋势,主要是因为没有足够的输电能力来支撑。国家电监会的一份报告指出去年中国风电场一半以上的电力都没有使用。

·8千万只智能电表。中国“十二五”规划计划2015年完成8千万只智能电表的部署,智能计量将贯穿商业与工业领域。GCIS的一份中国战略研究报告指出考虑到替换性采购需求,至2020年将有2.5亿只智能电表安装需求。然而,如此强势的增长造成的财政与生产的压力令人忧虑电表的精确度与寿命问题。

·天津生态城。中国快速的城市化发展,以及政府对于减少碳排的愿望,推动了建设更美好的城市的需求。距北京150公里的天津生态城是发展完美城市的一次尝试,据金融邮报报导,生态城的目标是建设当今世上最绿色的城市,规划中的生态城将由中国第一个智能电网系统供电,20%的电力来自于新能源。

·十个城市,千辆电动汽车。2009年中国启动了推进电动汽车发展的规划。项目从最初的10个城市扩展至全国25个城市。中国政府近期追加了150亿美元的投资。据PRTM管理咨询公司提供给世界银行的报告称中国的电动汽车发展计划主要集中在公交车与出租车,要适应私家车的使用需求,还需要在充电基础设施建设方面做大量工作。(中国智能电工网)
