S.A.T.E.

S.A.T.E. S.r.l. provides real time (RT) simulation models and

software and dynamic simulation services for processes and

machines, based on its proprietary software suites, such as

TGSim Plus

and COMPSYS

. These allow the study and

design of the physical and of the control systems considering

accurate realistic interactions of the rotating machines with

plants and all phenomena of relevance in the definition of new

installations and products development.

These software products are applicable during the design

phase to optimise or check the engineering solutions of the

hardware parts, e.g. process control and the piping flow

elements and valves.

S.A.T.E. uses its experience to satisfy the industry’s increasing

requirements, in particular the trade-off between the need for

fast reaction to market changes despite long lead item delivery,

and the complex system design and integration process for

which traditional engineering tools and approaches have

become insufficient.

In the last two years, S.A.T.E. has implemented and licensed

an RT dynamic simulator of a whole gas turbine system,

including all gaseous and liquid auxiliaries, to an international

OEM.

The simulator is based on a software suite, TGSim Plus,

running in the MATLAB-Simulink environment, which can

generate compiled versions of the code to run on RT operating

system platforms. The simulator can then be interfaced with the

real control system of the plant and used in the following ways:

For hardware in the loop (HIL) simulations to verify all

control system logics and feedback loops.

As a training tool for the plant operators.

As a troubleshooting tool to analyse cause-effect

relationship in large scale systems, where problems or faults

may arise due to complex interactions among physical

parts or among them and their controllers, sometimes with

large interconnection loops.

As a design and testing tool for plant diagnostic systems

based on simplified model-based or data analysis

algorithms that must learn from operational history; in this

case artificial faults injected in the model enable

Kop-Flex High Performance (HP) couplings have been supplied

to the global oil and gas industry for over 50 years and have

amassed over 1 billion hours of reliable operation in API 671

applications. HP couplings are precision balanced and are

offered in disc, diaphragm, and gear types. The company’s

latest innovation – HP Disc 2.0 – was developed to address

rotordynamic challenges presented by the highly efficient,

faster turbines of tomorrow. HP Disc 2.0 achieves the lowest

overhung moment in the industry (up to 30% lighter) and more

sizes to best fit your unique applications. Kop-Flex diaphragm

couplings are machined from solid stainless steel forgings with

unique profiles per application without welds. For

turbomachinery that has been running for decades, the

company offers its line of HP gear couplings; or it can assist in

retrofitting to a maintenance-free disc or diaphragm coupling.

Regal also has a Recertification Program to revitalise couplings.

The Kop-Flex Powerlign® torque monitoring system uses

non-contact phase displacement technology integrated into

the coupling to monitor transmitted power between

equipment over time and helps diagnose where performance

loss is occurring. Recently, a plant was able to retrofit a

Powerlign system into its equipment to determine that their

production limit was the result of compressor fouling; by

implementing an optimised washing schedule, they were able

to avoid a US$2 million capital investment to rerate their steam

turbine.

Milwaukee Gear manufactures custom gears, pinions, and

assemblies for customers that require helical and spur ground

gears to exacting specifications with traceability and reliable

lead times. Its expert engineering, on-site heat treatment

capabilities and passion for excellence have earned a loyal

customer base for over 90 years.

The Kop-Flex and Milwaukee Gear brands are part of Regal

Beloit Corp.’s Power Transmission Solutions business segment.

Regal Beloit Corp. is a leading manufacturer of electric motors,

electrical motion controls, power generation and power

transmission products serving markets throughout the world.
