Turbocompressor Control
 

Turbocompressors, also known as units, are large critical equipment widely used in industries such as petrochemicals, metallurgy, power generation, natural gas transportation, refrigeration, and power. The operational state of the units directly affects production efficiency. Therefore, the control of turbocompressors is crucial.

Based on years of experience in turbocompressor control and our in-house developed software packages, our company provides a comprehensive turbocompressor control system called ITCC (Integrated Turbocompressor Control System) based on the TRI-CON or SIEMENS PCS7-410F platform. Its applications include:

- CCS: Control of steam turbine/motor + compressor (centrifugal, axial flow, reciprocating, screw compressors, etc.)

- UCP: Control of steam turbine/motor + pump

- DEH: Control of steam turbine + generator

- SIS: Emergency shutdown interlock protection for units and facilities

We have rich experience and advanced, reliable, and safe control solutions for unit control. Our solutions cover functions such as steam turbine speed control, extraction, overspeed protection, compressor anti-surge control, unit performance control, shaft system instrumentation monitoring, oil and seal system monitoring, unit startup/shutdown sequence control, and interlock protection. These functions ensure the expected stability and reliability of your units, providing strong support for their long-term and efficient operation.

The latter section describes the functions of several canonical group control applications.
