GE OMNI MU360 MODULAR PROCESS INTERFACE UNIT Flexibility

Flexibility

By integrating binary inputs, outputs, and analogue connections into

one box, the MU360 offers a cost-effective solution for a multitude of

bay configurations. Up to two buses and two lines may be monitored

per box with a flexible configuration of up to 224 binary inputs or 140

binary outputs.

Reliable, Interoperable and Future Proof

The MU360 complies with the main standards for digital

substation IEC 61869-9. IEC 61850 edition 2.1 and IEC 61869

13. which guarantees its interoperability and compliance to the

requirements for being the physical to digital interface of modern

digital substations. Furthermore, measurements of each CT/VT

set may be broadcasted in protection and power quality profiles,

allowing multiple Protection, Automation and Control applications

to consume the data without needing extra footprint for acquisition.

Test Modes

IEC 61850 edition 2.1 provides standard mechanisms for testing

purposes, reducing commissioning complexity and allowing new bay

installations without affecting substation operation.

With the test modes in MU360 users can independently configure

mode and behavior of each logical devices allowing then to operate

as: On, Test, Blocked, Test/Blocked and Off.

A Safer and Cybersecure Substation

Transmitting the instrument transformers´ measurements digitally

through optical fibers eliminates the risk of inadvertent mishandling

of the current and voltage circuits and makes the relay room a safer

work environment, eliminating hazards and reducing the risk of

personnel injury.

To ensure MU360 have all this connectivity in a cybersecure way, it

has been designed according to IEC 62443 and have all capabilities

described by SL2 of this standard, including RBAC, secure boot and

signed firmware.

Reduce the Engineering Effort and Cost

The use of Process Bus with the MU360 drastically reduces the

need for trenches, ducts, glands, cable trays and copper hardwiring,

as the information is exchanged among IEDs using fiber optic cables

and ethernet switches.

Fewer cables to manage also means reduced engineering complexity

as extensive wiring schematics are replaced by standardized

version-controlled configuration files. Future reconfigurations are

automatically documented by the IED configuration tool.
