Reliable, high quality power is key to keeping the recently launched Dubai Metro running smoothly. ABB’s Substation Control and Monitoring Systems (SCMS) and low-voltage products are working together to deliver reliable power to Red line stations of Dubai Metro - a driverless metro network that is pegged as the world’s longest fully automated metro system to be completed in one phase.
The metro network is 75 kilometer long and will carry 23,000 passengers per hour per direction. The service has started with 12 trains on the tracks, which will go up to 44 once the remaining stations are operational next year.

As part of a long-term frame agreement with Dubai Electricity and Water Authority (DEWA), ABB has designed and installed Substation Control and Monitoring Systems (SCMS) for three 132/33kV gasinsulated switchgear substations for the Dubai Metro. The first two installed substations are currently supplying power to all Red line stations, whilst the third substation - installed in March 2009 – will supply power to the entire Green line once it is operational next year.

Boosting energy efficiency

ABB’s SCMS technology is designed to increase energy efficiency and grid reliability for the entire electrical network by using a powerful set of tools to monitor and manage power quality. The substations also feature fault recorders and tariff metering systems to carefully monitor performance and ensure smooth operation.

Meanwhile, ABB’s main distribution panels are responsible for the primary power distribution to the low-voltage network, which feeds the power distribution, lighting and HVAC (heating, ventilation, air-conditioning) systems within each metro station. The primary cabinets and motor control centers are designed using the ABB branded ArTu-K switchgear system.

For the low-voltage side of the project, ABB worked with authorized panel builder, Al Hamad Industries International (AHII). AHII has been a long-time ABB panel builder and the strong working relationship with the switchgear firm was one of the reasons ABB was able to clinch this major project.

ABB’s products, including circuit breakers, relays, control products and switches, were supplied to AHII, which assembled the switchgear and panels and in turn supplied them to the main contractor. ABB was also responsible for project coordination, including application engineering, design, supervision and supply.

ABB has extensive experience in powering metro stations globally, including the Delhi Metro in India and China’s Guangzhou and Shenzhen metro lines.
