505/505E
Digital Control for Steam Turbines
APPLICATIONS
The 505 and 505E are microprocessor-
based controls designed to operate steam
turbines of all sizes. The 505 is designed
to operate steam turbines using one or
two (split-stage) actuators to drive inlet
steam valves. The 505E is designed to
operate single extraction and/or
admission steam turbines. These digital
controls are field programmable. They use
menu-driven software to instruct site
engineers on programming the control to
a specific generator or mechanical drive
application. The 505 or 505E can be
configured to operate as a stand-alone
unit or in conjunction with a plant’s
Distributed Control System.
DESCRIPTION
Woodward’s 505 and 505E digital controls
use a 32-Bit Microprocessor to control
industrial sized steam turbines, small
utility turbogenerators, or turboexpanders.
The 505/505E package consists of printed
circuit boards in an enclosure designed to
be mounted within a system control panel.
An optional NEMA 4X enclosure is
available to allow these controls to be
mounted within harsh environments.
An Operator Control Panel is provided on
the 505’s front panel. Easy to follow
instructions are presented in English
through the OCP’s two-line display and
operators can view actual and setpoint
values from the same screen. Removable
terminal blocks allow for easy wiring and
installation.
COST-EFFECTIVE DESIGN
The 505/505E is a field configurable
steam turbine control and operator control
panel integrated into one package. A
comprehensive operator control panel,
including a two-line (24 characters each)
display, and a set of 30 keys is located on
the 505/505E’s front panel. This OCP is
used to configure the 505/505E, make
On-Line program adjustments, and
operate the turbine/system.
The 505/505E also performs as a first-out
indicator for system shutdowns, thus
reducing troubleshooting time. Multiple
system shutdowns (3) can be brought into
the 505/505E to allow it to shut down the
system safely, and latch-in the cause of
the shutdown.

505/505E

Digital Control for Steam Turbines

APPLICATIONS

The 505 and 505E are microprocessor- based controls designed to operate steam turbines of all sizes. The 505 is designed to operate steam turbines using one or two (split-stage) actuators to drive inlet steam valves. The 505E is designed to operate single extraction and/or admission steam turbines. These digital controls are field programmable. They use menu-driven software to instruct site engineers on programming the control to a specific generator or mechanical drive application.

COMMUNICATIONS

The 505/505E controls can communicate directly with plant Distributed Control Systems and/or CRT based operator control panels, through two Modbus® communication ports. These ports support RS-232, RS-422, and RS-485 communications using ASCII or RTU Modbus transmission protocols.

Communications between the 505/505E and a plant DCS can also be performed through hardwired connections. Since all 505 PID setpoints can be controlled through analog input signals, interface resolution and control is not sacrificed.

FLEXIBILITY

The 505/505E is field programmable, allowing site engineers to configure the control to their specific application, and make future control configuration changes. The 505/505E can be field programmed for mechanical drive or generator applications. Over 100 on-line tunables are available to allow program refinements while a unit is running. Inputs and Outputs are programmable as required by the application or interface.

SYSTEM PROTECTION

  • Integral Overspeed Protection Logic
  • First-out Indication (3 individual Shutdown inputs)
  • Bumpless transfer between control modes if a transducer failure is detected
  • Local/Remote Control priority and selection
  • Fail-safe Shutdown Logic

CONTROL

The following PIDs are available to perform as process controllers or limiters:

  • Speed/Load PID (with Dual Dynamics)
  • Auxiliary PID (limiter or control)
  • Cascade PID
  • Extraction and/or Admission PID (505E only)
