ABB has commissioned three traction substations that will power an electric bus network for passengers travelling to and from a university in Saudi Arabia.
The substations will enable emission-free transportation for students, staff and visitors at the King Saud bin Abdulaziz University for Health Sciences (KSAU-HS) in the capital city of Riyadh.
The newly built campus which spans 5km² will be served by a trolley bus system comprising ten stations each with two platforms.
As part of the project, ABB has built three converter substations that transform AC power to DC power needed to run the trolley buses.
Each 13.8 kV AC / 750V DC substation installation includes diode rectifiers, dry-type rectifier-transformers, auxiliary distribution systems, gas-insulated medium-voltage switchgear and DC switchgear.
The company, which equipped the substations with control and protection devices and a remote terminal unit (RTU), was responsible for the design, supply, installation and commissioning of the substations.
ABB substations business head Oleg Aleinikov said: "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."
