The full English name of ITCC is Integrated Turbine Compressor Control system, also known as the “compressor/turbine integrated control system”. This control system integrates the compressor’s pressure, flow rate, anti-surge control, turbine speed regulation, and turbine speed overshoot protection, facilitating control and management. The advantages are triple redundancy, higher security compared to DCS, a response time on the order of milliseconds comparable to that of ESD, and excellent anti-surge performance for unit control. The disadvantages are that its analog configuration is not as good as that of DCS.
Under normal circumstances, DCS only displays a lack of interlocking, while ITCC can achieve interlocking
DCS can also be interlocked; ITCC offers faster computation and scanning, greater specificity, and more professionalism, but it is less versatile.
I completely agree; it’s more difficult to learn*.
Yes, two systems that are not compatible – it’s quite cumbersome. However, ITCC still has a clear advantage in unit control. It’s being used a lot at the moment
It is not a concept at the same level; ITCC is an integrated control system for compressors/turbines, with its core functionality typically implemented by PLCs. PLC and DCS are concepts that refer to different ranges; DCS was initially focused on analog control, while PLC focused on digital control. With the development of computer technology, the boundaries between the two have become increasingly blurred
With the development of hardware and increasing speeds, is there a trend for DCS to completely replace PLCs?
