Introduction: T880 is an integrated turbine compressor control system developed by Hollysys for high-end users - CCS (Compressor Control System). The T880 control system fully integrates the design concept of triple redundancy, which can meet the requirements of real-time, reliability and stability of on-site important equipment control and protection.
peculiarity
Speed control: speed up, overcritical, variable speed control functions
Compressor control: constant air pressure, constant air volume, static blade control, anti-surge control
Interlock protection: start interlock, overspeed protection, anti-backflow protection, parking output
Auxiliary control: ontology monitoring, auxiliary control
parameter
Triple redundancy technology: all triple redundancy of the main control unit, IO module, bus communication, etc.
Compressor control: the control cycle is less than 30ms, which meets the requirements of real-time control.
Separation of control grade products (CCS) from safety grade products (ESD); CCS and ESD use separate CPU and main control cage respectively.
ESD degradation mode 3-2-0 (safety), CCS degradation mode 3-2-1 (availability).
Multi-layer redundancy, T880 system cooperates with Hollysys B series self-contained actuator to achieve multi-layer redundancy of the control system and actuator, which greatly reduces the unit shutdown caused by the failure of the actuator and solves the bottleneck problem of a single steam turbine regulating steam valve in the control circuit.
It can be seamlessly connected with Hollysys' SIS and DCS systems, and the interface is open to the outside world.
It has perfect online debugging and simulation functions.
A configuration language that conforms to the IEC61131-3 standard
We will provide customers with high-quality products and satisfactory services with honest and trustworthy, convenient and fast business methods and strict management.
This article introduces Hollysys/HollySys T880 triple redundant fault-tolerant compressor control system IO module products, if you are interested in Hollysys/HollySys control system, please also contact our customer service, we look forward to your call, hope our technology and service can bring you a better experience.
