Woodward Controls for Steam Turbines

 

505 and 505E
The Woodward 505 and 505E are microprocessor-based controls designed to operate steam turbines of all sizes. The Woodward 505 is designed to operate steam turbines using one or two (split-stage) actuators to drive inlet steam valves. The Woodward 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 Woodward 505 or 505E can be configured to operate as a standalone unit or in conjunction with a plant's Distributed Control System.

505DE
The Woodward 505DE is a microprocessor-based control with integral application software that is designed to control double automatic extraction/admission steam turbines. The turbine control architecture is patterned after the popular 505E Single Extraction/Admission Steam Turbine Control. Like the Woodward 505E, the Woodward 505DE uses configurable software for maximum field flexibility.

505CC-2
The Woodward 505CC-2 is a microprocessor-based control with integral application software designed to control a single-valve or two-valve (extraction/admission) steam turbine driving a one- or two-stage compressor load. The turbine control architecture is patterned after the popular 505 and 505E turbine controls. The anti-surge control provides the user with a choice between two algorithms-the standard Woodward anti-surge algorithm or a special "minimum transducer" design that adapts to variable molecular weights. Like the Woodward 505, the Woodward 505CC-2 uses configurable software for maximum field flexibility.

5009 and 5009LST
The Woodward 5009 and 5009LST (large steam turbines) controls are designed to provide highly reliable control on critical steam turbine applications. The Woodward 5009 can be configured to control condensing, backpressure, and single automatic extraction/admission turbines, while the Woodward 5009LST is focused on large reheat steam turbine applications. The Woodward 5009/5009LST is field configurable and uses Windows menu-driven software to guide site engineers on configuring the control to a specific generator or mechanical drive application. The Woodward 5009/5009LST can be configured to operate as a stand-alone unit or in conjunction with a plant's Distributed Control System. The Woodward 5009LST also contains programmable ladder-logic capabilities.

5009FT Triple Modular Redundant (TMR) Fault Tolerant Steam Turbine Control
Woodward’s 5009FT TMR controls industrial steam turbines of all sizes and types in system-critical applications requiring maximum reliability and availability. This steam turbine controller includes specifically-designed algorithms and logic to start, stop, control, and protect industrial steam turbines or turbo-expanders, driving compressors, generators, or pumps.
The 5009FT is a standard-off-the-shelf steam turbine control for use on industrial steam turbines used in critical compressor or generator drive applications.
This controller is comprised of Woodward’s field proven MicroNet TMR® hardware platform and standard steam turbine software algorithms, and is designed for use in standard OEM turbine packages or by system integrators in turbine upgrade projects. The 5009FT’s fault-tolerant design allows it to operate with any single point of failure without shutting down the turbine, and its TMR (triple modular redundant) design and hot-swap module capability, allows users to easily make system repairs while the turbine set is online and operating normally. This control’s special PID-to-PID logic allows stable control during normal turbine operation and bumpless control mode transfers during plant upsets, minimizing process over- or undershoot conditions. The 5009FT controller senses turbine speed via passive or active speed probes and controls the steam turbine through actuators connected to the turbine inlet steam valves.

 

MicroNet™ Plus
The MicroNet™ Plus control is a flexible, state-of-the-art VME-based, modular control system with redundant or simplex CPU and power supply options and a variety of I/O module choices. Additional chassis may be added to accommodate larger systems. CPUs may be simplex or redundant, depending on customer requirements. A simplex CPU system can be upgraded to redundant CPUs by simply adding a second CPU and making a minor software change. I/O Module selection is customized to match customer requirements. I/O can be configured in any combination of simplex, duplex, or triplex and in any combination of analog, discrete, and specialty modules. I/O modules allow for hot replacement without removing control power. The MicroNet™ Plus control utilizes Woodward’s proven graphical application programmer (GAP) software.  A Ladder Logic programming environment is also available for those users familiar with this programming structure.

2301D-ST
The Woodward 2301D-ST is a microprocessor-based control with integral application software designed for single-valve steam turbines driving either mechanical or generator loads. Like Woodward's 2301A line of controls, this control is housed in a sheet-metal chassis and consists of a single printed circuit board. To facilitate unit retrofits, the 2301D-ST's I/O terminals are located in the same general location as Woodward's 2301A line of controls. This control is designed to perform the core control functions of a small steam turbine package with integral process control. The application software is field configurable, allowing it to be configured and modified to meet site-specific requirements.

Peak 150
The Woodward Peak 150 digital control is designed to control a single-valve steam turbine driving a mechanical load. It provides tight control of speed (NEMA D) and includes an input for a 4–20 mA remote speed control signal, which can be used for a process-generated input to control the speed setting. Other features include dual speed control dynamics and overspeed trip test capabilities.

Atlas-II
Woodward's Atlas-II control is an industrial platform that offers robust, low-cost control for a wide variety of turbine, engine, and compressor applications. With a proven real-time operating
system and dedicated inputs and outputs, the Woodward Atlas-II provides reliable and deterministic performance for key prime mover control functionality.
