Can the ITCC integrated control system replace the Bentley 3500?
These are two completely different systems that cannot replace each other
The 3500 is primarily used for the monitoring and protection of shafting systems. Although the ITCC can also receive analog signals, its main function is still the control and protection of the entire plant system. Moreover, the reliability of using transmitters to transmit signals such as vibration and displacement is not very high, and such usage is rare; therefore, it’s not possible for the ITCC to replace the 3500.
3500 and ITCC complement each other in compressors and are both indispensable. The vibration displacement signals from the large-scale units collected by 3500 are processed and converted into 4-20mA analog signals, which are sent to the ITCC system for monitoring and interlock purposes; however, when the interlocks are disabled, the 3500 system also needs to be bypassed.
ITCC is a combination of unit control and safe shutdown systems; the 3500 system is used for monitoring mechanical equipment but cannot be involved in control, and the two cannot replace each other
As long as the vibration displacement, rotational speed, and phase at the site are converted into electrical signals, it can fully serve as a replacement. Because in 3500, too, the data acquisition triggers the output of a digital signal when it exceeds the set value, and this signal is then sent to the ITCC. Without a 3500 security level, the safety might be reduced
One is a control system, and the other is a monitoring system; they are two different things.
The next generation of the TSxPlus system will integrate signal modules for shaft vibration, shaft displacement, and thermal expansion differences, becoming a comprehensive solution for unit control systems
ITCC stands for Integrated Turbine Compressor Control System; the 3500 is merely a system for monitoring data such as vibration levels of the unit, and it is just one component of ITCC. This technology was introduced by Condensate Engineering, and now there are also manufacturers in China that produce similar systems.
