Compressor

The Woodward Integrated Compressor Control System (ICCS) as used by PM Control Systems is a flexible and comprehensive package specifically aimed at improving compressor train performance, reliability and protection by combining control functions into a tightly integrated system. ICCS solutions can include:

• Compressor multi-loop anti-surge valve control and process control.
• Steam turbine, gas turbine or electric motor control.
• SIL-3 safety.
• Quench valve control.
• Multiple compressor train control.
• Start/stop/loading/unloading.
• Shutdown interlocks.
• Flare valve control.
• Auxiliary and sequencing control.

• Superior dynamic performance of surge control and pressure
• override loops.
• Maximised compressor network efficiency through unique load sharing algorithm.
• Minimized gas recycling rate, optimum temperature control and prevention of prime mover overload during the startup of a
• refrigerant compression loop.
• Uncompromised compressor safety and high process stability through advanced fallback strategies.
• Accurate reproduction of dynamic responses of fast compressor control loops within NetSim (turbomachinery control emulation software linked to a plant operator training simulator).

PM Control uses Woodward’s proven NetSim simulation packages to provide integrated turbomachinery-specific dynamic modules of the compressor, prime mover and auxiliaries, along with real-time control modules that can run on a single computer. This benefits the user in running FEED/Feasibility/RCA studies and aids in control system design and testing.

NetSim emulates functionality of all system hardware components, accurately reproducing execution timing, I/O synchronization and data protocols.

• Validate control system design.
• Identify compressor process loop bottlenecks.
• Shorten commissioning time.
• Enable effective troubleshooting.
• Simplify DCS integration testing.
• Provide hands on turbomachinery control maintenance experience and training for plant personnel.
