Siemens Smart Infrastructure has installed process bus technology at the new high-voltage substation in Los Sauces for one of the largest Peruvian distribution network operators,
This process bus installation with Siprotec merging units and Siprotec protection devices is one of the first fully digitized energy automation system in operation. The new technology sets benchmarks with its future-proof design and will help optimize the entire operation of the power grid.
The process and station bus systems are physically split between two Ethernet networks. This design deliberately separates the applications, increases performances and improves cyber security.
'Siemens is driving the digitization of the power grid on all voltage levels,' said Robert Klaffus, CEO Digital Grid at Siemens Smart Infrastructure. 'The process bus technology in substations digitalizes the information at the process level and communicates via fiber optic cables to the protection and station control system. Efforts for cabling, installation and maintenance are significantly reduced and at the same time the flexibility of the overall protection system is increased. A particular advantage of the process bus is the significantly increased safety for people and the system itself. Together with our local Siemens team in
