ABB delivers power to King Saud bin Abdulaziz University green transport system
Swiss-based power group ABB said it has commissioned three substations to deliver electricity to a new bus network and enable emission-free transportation for students, staff and visitors at the King Saud bin Abdulaziz University for Health Sciences in Riyadh.
The newly built campus spans five sq km and will be served by a trolley bus system comprising 10 stations each with two platforms.
As part of the turnkey project, ABB said it has constructed three converter substations that transform the AC (alternating current) power from the local utility network to the DC (direct current) power needed to run the trolley buses.
The buses operate on separate bus lines and are fed by a 9km long catenary line. Priority control at crossroads to other streets helps ensure smooth and efficient traffic and passenger movement.
ABB said it was responsible for the design, supply, installation and commissioning of the substations.
ABB also supported the development of the operational and safety systems required for maintaining and servicing the electrical equipment within the new micro-network.
"ABB has a proven track record of providing innovative solutions to the railway and urban transportation sectors and we are proud to contribute to this project," said Oleg Aleinikov, head of ABB's substations business, a part of the company's Power systems division.
"The technologies deployed will help ensure reliable and high-quality power supply to the electric bus system and provide an environmentally friendly transportation solution across the university campus."
KSAU-HS is the first public university in the region, specialising in health sciences and is located in the eastern part of the capital city Riyadh.
In addition to the university clinic and various scientific and medical institutes, the site includes a large residential area for students, lecturers and staff.
ABB has executed several other transportation related projects in the Middle East, including the Dubai Metro and the King Abdullah Financial District monorail system in Riyadh.
Most recently, ABB has been involved in the delivery of the traction power supply for the automated people mover system for the New King Abdulaziz International Airport being built in the north of Jeddah.
