Overview

Si-TEC BDG

Si-TEC ADG-T

Si-TEC ADG-TT

Si-TEC Range of Steam Turbine Governors

The Si-TEC BDG and Si-TEC Xtend ADG are steam turbine controls, specifically designed for mechanical drive applications (i.e. pumps, fans, shredders, mills, etc.). These controllers offer optimum steam turbine performance during transient and steady state conditions, utilising their wide range of control speed PID’s.

The Si-TEC BDG (Basic Digital Governor) design is based on the very successful Si-TEC Xtend ADG Advanced Digital Governor. The compact design, user friendly interface, onboard data logging and wide range of PIDs makes the BDG a standard choice for steam turbine control solutions. ADG is utilised for constant and variable speed “single drive“ application, and for “dual drive“ (tandem) load sharing applications.

Si-TEC ADG-T

The Si-TEC ADG (Advanced Digital Governor) is a steam turbine control designed for mechanical drive applications (i.e. pumps, compressors, fans, shredders, etc.). Originally developed in 1991 it has since then proven to be the ultimate in steam turbine governing control, with its many features and wide range of speed PID’s the Si-TEC ADG has become the standard choice for many steam turbine operators.
ADG-T is utilised for constant and variable speed “single drive“ application.

  • Precise speed governing typically within 0.1 % of operating speed at steady state
  • Dual MPU (or prox.) speed sensors for redundancy
  • Auto run up and warm through interpolating multiple speed PIDs
  • Process control
  • Variable speed governing control referenced from internal or external set points
  • Constant speed governing control referenced from internal set points
  • Controlled test of overspeed protection
  • Extensive alarm functions
  • On-board diagnostic
  • Dedicated communications port for customer PLC/DCS interface
  • Compatible with all Si-TEC support PC software
