The base 505 model is designed for simple single valve steam turbine applications where only basic turbine control, protection, and monitoring are required. The 505 controller’s integrated OCP (operator control panel), overspeed protection, and trip events recorder make it ideal for small steam turbine applications where overall system cost is a concern.

The 505XT model is designed for more complex single valve, single extraction or single admission steam turbine applications where more analog or discrete I/O (inputs and outputs) are required. Optional inputs and outputs can be connected to the 505XT controller via Woodward’s LinkNet-HT distributed I/O modules. When configured to control single extraction and/or admission based steam turbines, the 505XT controller’s field-proven ratio-limiter function ensures that interaction between the two controlled parameters (i.e., speed and extraction or inlet header and extraction) is correctly decoupled. By simply entering maximum levels and three points from the turbine’s steam map (operating envelope), the 505XT automatically calculates all PID-to-valve ratios and all turbine operation and protection limits.

The 505 and 505XT controllers are designed to operate single valve, or single extraction/admission industrial steam turbines of all sizes and applications. These purpose-built steam turbine controllers include the following functionality and logic to control and protect industrial steam turbines.

Æ Three critical speed avoidance bands

Æ Auto start sequence (hot and cold starts)

Æ Multiple ratio/limiter decoupling modes (505XT only)

Æ Overspeed detection and trip

Æ Reverse rotation detection (with two proximity probes)

Æ Manual operation valve limiters

Æ Programming, service, and operation password security

Æ PID-to-PID communications for bumpless transfers

Æ First-out event indication (shutdowns and alarms)

Æ Zero speed detection (with use of proximity probe)

Æ Peak speed indication for overspeed trip

Æ Remote analog setpoints for speed/load, aux, and cascade

Æ Fail-safe protection logic (with processor, memory, and data

bus error detection)

Æ High-speed digital communications to Woodward actuators and
