The second independent power supply system for Dubai Metro is energized

The MPS2 has a maximum capacity of 160 MVA with dual step-down 132/33 kV transformers. The MPS2 is fully automated (unmanned) and equipped with advanced protection and monitoring systems in addition to fire fighting systems. The other MPS3 Substation is located as well at Union Square which is currently under final testing phase for powering the Green Line network.

Mr. Adnan Al Hammadi, Rail Construction Director, RTA, said," The electrically powered metro trial runs will continue in the next few months. MPS 1 & 2 together will provide entire power supply for the metro operation including rail stations for the Red Line serving the metro route of 52.1 KM from Rashidiya to Jebel Ali."

"The design of Dubai Metro power network is very robust and reliable. In the unlikely event of total failure of any one MPS the metro operations will not be affected on the entire rail network. Dubai Metro utilizes the concept of braking power regeneration to help minimize power consumption from DEWA grid,"

e added.

The construction and commissioning of 132 KV substations is a complex network of actions involving various experts in different disciplines of engineering. The Rail agency engineers did not spare any effort to ensure all parties are in co-ordination, issues are resolved and decision were promptly taken in consultation with DEWA to achieve this important milestone. Every one in the team worked round the clock to complete the specified works in a given time schedule.

"The power system is one of the major components in Metro operation. Special emphasis was therefore placed to ensure very reliable and failsafe system for Dubai Metro. RTA continuously co-coordinated with DEWA to ensure the implementation of power network in complete compliance with DEWA and international standards" Mr. Adnan added.

The Metro Power system network will be fully monitored and controlled from dedicated Operations Control Centre (OCC) for all normal and emergency situations to ensure safe and reliable metro operations.

The Electrically powered Dubai Metro will strengthen the environment friendly concept to which Dubai is committed and indirectly help reduce the air pollution by reducing vehicular traffic on the road.

On this regards, RTA extends thanks and appreciation to Dubai Electricity and Water Authority (DEWA) for all the support they provide to make this mission a success.
