Unit Control & Protection Systems

Reliable, Safe and Future-Ready Operation of Critical Assets

Unit Control & Protection Systems

Explore MAS control & protection on applications:

Control and protection systems form the core operational layer of any critical asset, upon which all higher-level automation and digital systems depend.

MAS delivers advanced engineering solutions for the upgrade, retrofit and integration of control and protection systems, ensuring stable operation, regulatory compliance and long-term system integrity.

MAS Unit Control & Protection Engineering

MAS designs control and protection systems for operational continuity and maximum uptime: 

  • Dual and triple redundancy architectures (~99.999999% availability) 
  • Fault-tolerant control logic ensuring continued operation under partial failure
  • High system resilience under abnormal and transient conditions

Unified upgrade of control and protection systems

  • Integration of control and safety systems (eg. ESD) with optimised tuning, supporting seamless operations without sacrifice safety 
  • Harmonised control logic across multi-vendor environments
  • Elimination of control conflicts and delayed system response

MAS ensures precise and stable system behaviour under dynamic conditions:

  • High-speed control loops and real-time response 
  • Advanced control tuning and validation 
  • Stable operation under load variations and transient events

MAS systems are fully aligned with international and operational requirements: 

  • Engineering in compliance with international (API, IEC, etc.) and industry-specific evolving standards
  • Alignment with safety and certification frameworks
  • Full adherence to OEM specifications

MAS engineers control and protection systems as part of a unified operational environment:

  • Seamless integration with Power /Energy Management and Load Shedding Systems, Station Protection Systems, adding capability to isolate and manage faults before they disrupt operations.
  • Structured system communication with SCADA and digital platforms

MAS delivers complete asset recapitalisation engineering, extending the lifecycle of existing equipment and providing substantial benefits, while avoiding unnecessary capital expenditure.

Where possible unit level upgrades  is performed under live operational conditions, ensuring continuity of operationof the overall plant.

MAS operates within a strong OEM ecosystem, ensuring long-term reliability, maintainability and lifecycle support:

  • Deployment of OEM-certified technologies 
  • Manufacturer-approved system configurations 
  • Guaranteed spare parts availability and warranty

MAS applies structured engineering methodologies:

  • System architecture design and specification 
  • Simulation and functional validation 
  • Structured FAT (Factory Acceptance Testing)
  • Comprehensive SAT (Site Acceptance Testing)
