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.
