GE OMNI MU360 Reliable, Interoperable and Future Proof

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.

GE OMNI MU360 MODULAR PROCESS INTERFACE UNIT

Your bridge from physical to digital worlds:

Process Interface Unit for Digital Substations

MU360 is the Process Interface Unit (PIU) with analog and binary interfaces for full

switchyard modelling, control and digitization using IEC 61850 and IEC 61869 standards and

protocols such as Sampled Values (SV), GOOSE, MMS and PTP.

The MU360 unlocks the full value of a completely digital substation, capable to be a single

I/O interface for Protection, Automation and Control applications to bay IEDs. Limiting the

field wiring just up to the MU360 reduces project complexity by reducing cabling, terminals,

and physical connections, which combined with a complete set of logical nodes allows

design standardization on the yard. Bay level IEDs can use data from redundant MU360

units, increasing system availability. Bay level IEDs can also be quickly replaced or added

using IEC 61850 test modes as no field wiring is involved. The MU360 has the additional

benefit of improving CT performance and cost through a lower connected burden and a

reduction in the number of CT cores required for an application.

ABB PCMU The solution to mitigate risk and save costs on relay upgrades Relion 615 Series

The Relion 615 Series is a comprehensive family of protection relays per

fectly aligned for the protection, control, measurement, and supervision of

utility substations and industrial systems. It includes dedicated protection

relays for feeder, motor, and transformer protection.

The PCMU provides a seamless and cost effective way to re

place legacy relays. It reduces risk and saves money. A detailed

comparison of the PCMU series vs the traditional replacement,

which requires an adapter plate and is not wire-alike, shows

how users save time and money when replacing protection

relays and requires less personnel for less time.

The PCMU replaces DPUs of the 245. 445. and 2000 series

and MSOC relays. To request a training or quotation, contact

your ABB representative with the style numbers of your existing relays.

ABB Bus protection via GOOSE

Bus protection via GOOSE

The IEC 61850 implementation in PCMU MSOC includes

fast peer-to-peer communication, over the substation bus.

Use GOOSE communication between PCMU MSOC relays of

the incoming and outgoing feeders of a substation to form a

stable, reliable, and high-speed busbar protection system. The

cost-effective GOOSE-based busbar protection is obtained by

configuring the relays and the operational availability of the pro

tection is assured by continuous supervision of the protection

devices and their GOOSE messaging over the station bus. No

separate hard-wiring is needed for the horizontal communica

tion between the switchgear cubicles.

Pre-emptive condition monitoring

For continuous knowledge of the operational availability of the

PCMU MSOC features, a comprehensive set of monitoring

functions to supervise the relay health, the trip circuit, and the

circuit breaker health is included. The breaker monitoring can

include checking the wear and tear of the circuit breaker, the

spring charging time of the breaker operating mechanism and

the gas pressure of the breaker chambers. The relay also mo

nitors the breaker travel time and the number of circuit breaker

operations to provide basic information for scheduling breaker

maintenance.

ABB PCMU Pre-emptive condition monitoring

Standardized communication

As a standard feature, PCMU MSOC supports the IEC 61850

standard for communication between devices within the subs

tations along with the industry standards DNP 3.0 and Modbus

protocols. The implementation of the IEC 61850 substation

communication standard in PCMU MSOC encompasses both

vertical and horizontal communication, including GOOSE mes

saging and parameter setting according to IEC 61850-8-1. The
