19 GE Centrifugal & Axial Compressors
With extensive experience as a manufacturer of compressors and all types of drivers, and
engineering and field services for compression stations, our specialized teams develop systems to
control the equipment packages and the associated auxiliaries or processes as required.
Control systems:
Our Integrated Driver-Compressor Control system is a complete integrated solution, providing
protection and monitoring to maximize the security of the compressor against potentially harmful
surge conditions, while enhancing process efficiency and availability. This integrated control
system provides critical process control for the entire compression train, its auxiliaries and related
process equipment. Compatible with a variety of drivers and compressors, it runs on the GE Mark
family of control platforms or on GE Fanuc PLC’s as dictated by the applications. Simplex, Dual,
and TMR control system redundancy options are available.
Combining the driver and load compressor control in a single platform provides advantages to the
customer:
- Common spares for both driver and compressor control systems reduce the overall inventory
requirements
- A smaller physical footprint means that compressor control hardware can be included in the
same cabinet as the driver control hardware.
- The same Technical Advisor can handle commissioning and startup of both the compression
train and driver.
- Common software tools and diagnostics for maintenance of driver and compressor controls
simplify maintenance and uprates, and also reduce startup time and cost.
- Training time and costs are reduced with a single control system used for both driver and
compressor controls. This applies to both initial and on-going training costs over the life of the
control system.
Control Systems
Anti-surge protection and process
control
Anti-surge control algorithms implemented
within the integrated control system are based
on the knowledge acquired through our
expertise as a leading compressor
manufacturer and experience on thousands of
applications. Different control strategies are
available to meet the needs of the application.
All provide both closed and open loop controls
to better react to small and large process
disturbances. Different process control and
load bearing functions can be provided.
Dynamic simulation
Dynamic simulations ranging from a single
loop to a more complete process configuration
are possible to define anti-surge valves, hot by
pass requirements, piping optimization for
improved compressor protection and starting
conditions for electric motor drives.
