Process Bus and IEC 61850-9.2 LE
Available in Easergy MiCOM Px40 protection relays
Designed for digital substations with demanding protection applications in utilities, Easergy MiCOM Px40 series with Process Bus offers a reliable solution compliant to latest standards of IEC 61869 and IEC 61850 9-2 LE including PRP redundancy and cyber security. Available in Easergy MiCOM feeder protection, line differential protection, distance protection, busbar protection and transformer protection.
Process Bus is a key brick for digital substations in electric utilities and is a future ready solution for network automation. It provide opportunities to improve the overall cost of designing, installing and testing of protection and control systems.
Customers can benefit from Process Bus by improving personal safety, linked to converting analog power measurements to digital communication signals and transmitting on a fast and redundant fiber optic network with the support of a SAMU or merging unit. Information exchanged between primary equipment and control centers is not only safer, but shared using secure communication enabled by products that conform to latest cyber security standards. Such products offer full interoperability with other manufacturers to make systems more flexible and user friendly.
The products are designed to the latest standards: IEC 61869, IEC 61850-9-2 LE use sampled values (SV) for calculation and protection in electrical networks.
With more than 100 years experience and more than 600,000 relays in the field, Easergy MiCOM protection relays offer a reliable way to introduce Process Bus in your network. At Schneider Electric, reliability and customer satisfaction is our top priority, especially whilst offering the latest features and products that take a step forwards in reliability and safety.
Up to 40% cost savings on protection and control installations
- Raw materials significantly reduced, copper reduction with Ethernet cables
- Cubicle engineering and wiring verification reduced by as much as 70%
Improved safety of your personnel
- Replacing analog with digital sampled values, with the inherent isolation from the primary circuit allows dangerous levels of voltage and current to be completely eliminated from the protection cubicle
- Safer, even in the case of maintenance or replacement, signals are as simpler and safer to connect and reconnect
Full interoperability in multi-vendor systems
- Complete multi vendor environment thanks to full compliance with process bus latest standards IEC 61869 & IEC 61850-9-2 LE
Improved reliability & availability of the protection network
- Ethernet standardization brings redundancy and security of the communication channel so that you are never without mission critical process bus data
- Process bus can be combined with PRP (Parallel Redundancy) in Easergy MiCOM Px40 series
- Combine with our advanced cyber security features, like RBAC means all that data has not only redundancy, but is also fully secured to the latest international security standards
Process bus is a critical brick for building digital substations in demanding applications within electric utilities and energy intensive customers.
