Advanced gas turbine control system The Sentinel-C series of turbine control systems were designed specifically for the retrofit of heavy duty gas turbine controls; in particular, Speedtronic and LA families of turbine controllers. The control system was originally developed utilising the robust Allen Bradley PLC-5 family of processors, and has since been upgraded using the latest Allen Bradley PLC, Control Logix. This has been introduced to Sentinel range, which gives a greater flexibility and faster response time to the overall system. Both processors perform the sequential logic and closed loop control function, which are necessary for gas turbine control.
Turbine control philosophy of the original system is maintained, and is easily adapted to site specific requirements.
