The ABB intelligent MCC

The ABB intelligent MCC

The project includes four ABB MNS iS Power and Motor

Control Centers for a total of over 50 sections and 160

feeders in all kind of configurations, from the Direct On Line

starters to the highest version of the ABB softstarters. In

order to optimize the E-house layouts two of the ABB MNS iS

where provided in back to back configuration granting a more

efficient footprint.

MNS iS is the latest evolution of the ABB Low Voltage Power

and Motor Control Center: the “Intelligent switchgear”.

The MNS iS intelligence is guaranteed by the complete

integration and harmonization of all the different control,

protection and data processing functions into the MNS iS

concept.

The MNS iS network is based on distributed microprocessor

modules (MControl) connected through a serial gateway

interface (MLink) to a local Human System Interface (MView)

and to higher level systems.

- MControl: the microprocessor unit performs all the

protection control and monitoring functions and grants

connection to and from each single feeder or motor unit.

- MLink: the MNS iS interface module grants connectivity

from the local control modules to any higher system and

to the local Human System Interface.

- MView: a local Human System Interface based on touch

screen technology providing easy access to all kind of

data and control functions.

The use of the programmable microprocessor based

technology in conjunction with a strong focus on the design

optimization grant an overall reduction of the control and

power components with the advantage of reducing potential

point of failure and spare parts.

Results and customer’s benefits

As a result of all the integration and optimization activities,

the WAGP Utorogu and Oben Gas Compressor Stations were

delivered in prefabricated E-houses pretested and preset to

minimize the field installation and start-up activities.
