ABB为中国提供价值4亿4千万美元的电力传输系统
 
Zurich, Switzerland, Dec. 18, 2007 – ABB has won orders worth $440 million from the State Grid Corporation of China and other partners to provide new ultrahigh-voltage technology for the world’s longest power transmission link.

瑞士苏黎世12月18日消息——ABB从中国国家电网集团和其他合作伙伴手上赢得了价值4亿4千万美元的订单，为全球最长的电力传输网提供新的超高压技术。

The power superhighway running 2,000 kilometers (1,240 miles) from western China to the highly industrialized coastal area in the east, will have a capacity of 6,400 megawatts (MW). That is enough to meet the needs of about 31 million people in China, based on average consumption per capita. The link from the Xiangjiaba hydropower plant to Shanghai is scheduled for completion in 2011.

该超高速电力传输线从中国的西部延伸到工业高度发达的东部沿海地区，全长2千公里（1240英里），容量将达6400兆瓦。根据人均平均消费量，这将可以足够满足中国大约3千1百万人口的用电需求。这条从向家坝水电站到上海的电力线预计在2011年完工。

The ultrahigh-voltage direct current (UHVDC) link comprises two substations and a power transmission system using breakthrough technology to transmit electricity at ultrahigh voltage (800 kilovolts), which will minimize the amount of power lost in transmission.

该超高压直流输电(UHVDC)线包括两个变电站以及一个采用了突破性超高压（800千伏）电力传输技术的电力传输系统，这将减少传输过程中的电力损失。

Increasing the voltage level of electrical transmission creates considerable advantages for the environment, including lower electricity losses and the use of less land compared to traditional overhead lines. UHVDC is particularly suitable for vast countries like China, where the centers that need power are often located far from power sources.

跟传统的高架线相比，增加电力传输的电压水平可以为环境带来很大的好处，包括更低的电力损失以及占用更少的土地。超高压直流输电技术特别适合类似中国这样领土广阔的国家，这些国家需要电力的中心区域一般离发电站都较远。

This project represents a number of breakthroughs in electrical power transmission:

该项目在电力传输领域展现了许多突破点：

* The 6,400 MW power rating is more than double the most powerful rating in operation today

6400兆瓦的额定功率是是世界上现有最大额定功率的双倍还多

* At 2,000 km, the transmission line will be the longest in the world

2000公里的传输线将成为世界上最长的电力传输线

* Transmission losses will be less than 7 percent, significantly less than the losses from conventional 500-kilovolt (kV) high-voltage direct current (HVDC) transmission schemes. The savings from using UHVDC compared with HVDC are equivalent to the annual power consumption of more than 900,000 people in China.

电力的传输损失将少于7%，远远低于传统500千伏高压直流(HVDC)传输计划的损失量。对比高压直流技术，使用超高压直流技术节省的电量相当于中国超过90万人口的年均用电量。

“Ultrahigh voltage transmission is a vital new technology for the efficient use of hydropower generated in remote areas,” said Peter Leupp, head of ABB’s Power Systems division. “ABB technology, which plays an essential role in this project, can support the economic development of some of the world’s most populous regions, while lowering environmental impact."

ABB电力系统部主管Peter Leupp表示：“超高压传输对远程地区所发水电的高效利用是一项重要的新技术。在这项工程中扮演着重要角色的ABB技术可以支持一些世界上人口最广地区的经济发展，同时降低对环境的不良影响。”

UHVDC transmission is a further development of HVDC, a technology pioneered by ABB more than 50 years ago. The new technology, using thyristor valves equipped with newly developed six-inch thyristors (power semiconductors) and an advanced control system, allows the biggest capacity and efficiency leap in 20 years. The increase became possible following advances in basic research in a number of fields, including the development of new materials for outdoor insulators and advanced control systems with extremely high calculation capacity.

超高压直流传输技术是对ABB在50多年前首先开创的高压直流传输技术的一个继承发展。这项新技术使用配备新开发的6英寸晶闸管（功率半导体）和一个先进的控制系统的晶闸管阀，在20年实现最大容量和效率飞跃。伴随着许多领域基础研究所取得的进步，包括户外绝缘器新材料和具有极高计算能力的先进控制系统的发展，使这一改进成为可能。

ABB is a leader in power and automation technologies that enable utility and industry customers to improve performance while lowering environmental impact. The ABB Group of companies operates in around 100 countries and employs more than 110,000 people.
