The 505DR® dual-redundant steam turbine control is a state-of-the-art digital control platform designed to reliably control and protect single valve and single-extraction steam turbines with the advantage of dual-redundancy for maximum turbine reliability and availability. Redundancy is managed at the operating system level using Woodward’s RTN (Real Time Network), allowing ultra-fast changeovers and “bumpless” transitions.
Steam Turbine Control
Driving generators, compressors, turbo-expanders, fans, and pumps.
The 505DR is a highly efficient redundant turbine control. It includes the turbine control, system sequencer, operator control panel and first out indicator. This design minimizes external devices and wiring and eases troubleshooting.
The 505DR® system assigns one control as System Controller (Syscon) which actively controls the turbine. The second unit is configured as Backup. The system automatically assess the heath of the Syscon and will initiate a fast switchover when a failure occurs. Switchover can also be initiated manually. The system tightly synchronizes software states and memory from the Syscon to the Backup, insuring that control outputs remains steady with no effect on turbine operation (a true “bumpless” transition).

Woodward also offers an optional FTM (Field Termination Module) to allow easy multiplexing of redundant signals and facilitates quick installation and commissioning. (5541-705)
