ABB's integrated power solution for giant aluminum plant

ABB 为超大型铝厂提供完整综合电力解决方案

2006-05-26 - ABB is supplying a complete integrated power solution – including process-critical rectifiers, unique rectifier control systems and award-winning current sensors – for the biggest aluminum potline ever built.

“ABB is the only company with the capability to supply an integrated power solution of this scope and complexity,” says Max Wiestner, industry manager for ABB’s aluminum business.

2006-05-26—ABB正在为最大的铝电解槽提供一个完整的综合电力解决方案，该方案包括关键过程的整流器，单一整流器控制系统以及曾得奖的电流传感器。ABB铝事业部产业经理Max Wiestner表示：“ABB是唯一有能力提供这样大范围和复杂性综合电力解决方案的公司。”

The 360-pot Sohar aluminum plant in Oman will have a production capacity of 360,000 tons and be the biggest aluminum potline in the world when it goes on stream in March 2008. Sohar is a joint venture between industry and regional leaders Oman Oil Company, ADWEA (Abu Dhabi Electricity and Water) and Alcan.

具有360个铝罐的阿曼苏哈尔铝厂在2008年3月投产之后，将以36万吨的年产能成为世界上最大的铝电解槽。苏哈尔铝厂是阿曼石油公司和阿布扎比水电局（ADWEA）以及加拿大铝业公司（Alcan）的合资公司。

ABB’s scope of supply includes five giant 113 kA / 1650 VDC rectifier transformers – the most powerful ever built, each one weighing more than 300 tons – five AC 800PEC high-speed control and protection units for the rectifiers, a level-2 SCADA (supervisory control and data acquisition) system for the rectifier station and gas insulated substation, and ABB’s recently launched and award-winning fiber-optic current sensors (FOCS).

ABB的供应范围包括五个由此以来最大功率的大型113 kA / 1650 VDC整流器变压器，每个变压器的重量均超过300吨，五个用于整流器的交流800PEC高速控制保护装置，一个用于整流器站和气体绝缘变电站的级别2的监测和数据采集（SCADA）系统，以及ABB最近发布的、获奖的光纤电流传感器（FOCS）。

Rectifiers – key to the process

整流器——过程的关键

Rectifiers are the critical components in a smelter potline. They convert AC to DC power which is then passed through the molten electrolyte in the pots to form aluminum.

If the rectifiers fail and the line shuts down, the molten aluminum will “freeze” within hours, at a cost of $100 million or more.

整流器是熔炉电解槽中的关键组成部分。它们把交流电转化成直流电，然后在槽里熔化的电解液中传递，从而使电解液形成铝。倘若整流器出了故障导致整个生产线停工，那些熔化的铝将在几个小时之内冷却下来，代价将是1亿美元甚至更多。

Another key contributor to process reliability is ABB’s FOCS technology, which has revolutionized current measurement in large power-consuming applications like aluminum smelters.

另一个过程可靠性的关键因素是ABB的FOCS技术，是一项在例如铝熔炉等大型能耗应用中具有革命性的电流测量技术。

Alcan had previously tested FOCS at a smelter in France and were very impressed with the results. Compared to alternative current measurement technology FOCS weighs 20 kg against the conventional 2,000 kg, takes four hours to install instead of 40, improves accuracy by a factor of 10 to an unrivalled 99.9 percent, and is immune to electromagnetic interference.

Alcan已经在法国的一个熔炉里测试过FOCS技术，并对结果印象深刻。与交流电测量技术相比，FOCS仅重20kg，而传统的重2,000kg，FOCS仅需要四个小时即可安装完成，传统的则需花40个小时，FOCS的精确度更是从传统的10%提高到无可匹敌的99.9%，而且FOCS具有防电磁干扰功能。

On the control side, the AC 800PEC uniquely combines in a single modular system the high-speed control requirements of large rectifiers with low-speed control tasks usually carried out by separate PLC units.

在控制端，交流式800PEC独特地结合了在一个单一模系统里大型整流器所需要的高速控制要求和通常由独立PLC装置执行的低速控制任务。

Industrial complex

工业联合体

The Sohar aluminum plant is part of a massive greenfield industrialization project in Oman to establish alternative sources of revenue to oil and gas. In addition to the smelter, the project includes two steel plants and a chemicals plant, all of which will be located 12 kilometers inland from the port of Sohar.

苏哈尔铝厂是阿曼用于建立油气可选择资源收入而大力发展的工业化项目之一。除了铝厂，该项目还包括两座钢铁厂和一座化学厂，这些厂都是位于距离苏哈尔港12公里的内陆地方。

Already a second potline of the same size and capacity is planned for construction later this decade.

与现在同样大小和容量的第二个铝电解槽已经在筹建计划中，将在未来的十年里动工。

ABB is the market and technology leader in power conversion for smelter applications, with more than 80 years’ experience, a global market share of 50 percent, and a full scope of supply capability.

ABB是熔炉电流转换应用中的市场和技术领先者，具有80余年的历史，全球市场占有率达50%，以及全范围的供应能力。
