Siemens supplies process bus technology to high-voltage substation in Peru
Process bus significantly increases level of digitalization in substations
Faster installation and commissioning
Improved system reliability
Benchmark for future-proof design
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, Luz del Sur. 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.

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, Luz del Sur. 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.
Luz del Sur is currently expanding its 220 kV network. Instead of conventional 1:1 cabling between the transducer and the protection device, a merging unit records the measured values from the transducer, converts them into digital format and sends them to the respective protection units via a fiber-optic Ethernet cable. The merging unit is a modular, interoperable and powerful solution between primary and secondary technology which offers multifaceted process data recording, self-sustaining automation and secure communication. In total, 13 Siprotec 6MU85 merging units are used in this latest installation in Los Sauces, which is one of the first to utilize this technology on a large scale. The process bus from Siemens makes it possible to cover the digitalization along the process level using merging units to improve the reliability of the system, optimization of the installation, reduction of hard-wired components, and security of the maintenance staff.
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 Peru, we are proud that our customer Luz del Sur
is planning to adopt process bus technology as the standard for the implementation
of all its new high-voltage substations.”
