Peak® 150 Digital Control

The Woodward Peak® 150 digital control is designed to control a steam turbine driving a mechanical load. It provides tight control of speed (NEMA D) and includes an input for a 4-20mA 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.

   



Flex500 Digital Control for Turbines, Engines or Compressors

The Flex500 control system is a custom programmed industrial hardware platform that offers robust, low-cost control for a wide variety of turbine, engine, and compressor applications. Designed to function as a distributed control system, Woodward-based RTCnet™ and/or LINKnet HT™ distributed I/O modules can be used to expand the number and type of input and output signals as required. Ethernet, serial and CAN communication ports, and the related Modbus® TCP/IP and CANopen protocols also make this platform ideal for functioning as part of an overall plant distributed control system (DCS) or as a standalone controller. Four Ethernet ports and four CAN ports allow for the network flexibility and redundancy necessary for today's critical control system architectures.




2301E-ST Steam Turbine Control

The 2301E-ST is a steam turbine control with internal algorithms designed to start/stop, control, and protect a small steam turbine driving a generator, pump, or compressor. This control?s field configurability allows it to be easily configured by the user for a diverse range of applications. The 2301E-ST?s integrated generator power sensor and load-sharing capabilities also make it ideal for small turbine generator sets where a cost-effective control solution is essential.




505DE Steam Turbine Control

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 505E, the 505DE uses configurable software for maximum field flexibility. The control hardware consists of four plug-together modules housed in a rugged metal chassis. The SmartCore module and the analog I/O module contain the I/O required for double extraction turbine control. The main processor and the Ethernet port are located on the Pentium CPU module. The Power Supply module (24 Vdc) is provided to power the entire control assembly. The control also contains 12 relay drivers for external use.

   




505 and 505E Microprocessor-based Controls

The Woodward 505 and 505E are microprocessor-based controls designed to operate steam turbines of all sizes 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 (DCS).





505CC-2 Steam Turbine Control

The Woodward 505CC-2 is a microprocessor-based control with integral application software designed to control a single-valve or two-valve steam turbine and its 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 505, the 505CC-2 uses configurable software for maximum field flexibility. The control hardware consists of four plug-together modules housed in a rugged metal chassis. The SmartCore module contains the basic I/O for turbine control. An analog I/O module interfaces with the signal I/O associated with the one- or two-stage load compressor. The main processor and an Ethernet port are located on the Pentium CPU module.




5009 Steam Turbine Control

The Woodward 5009 control is designed to provide highly reliable control on critical steam turbine applications. It can be configured to control condensing, back-pressure, and single automatic extraction/admission turbines. The 5009 is field programmable and uses Windows™ menu-driven software to guide site engineers on configuring the control to a specific generator or mechanical drive application. The 5009 can be configured to operate as a stand-alone unit or in conjunction with a plant's Distributed Control System (DCS).

   



Atlas ll Control System

The Atlas-II? control is an industrial platform that offers robust, low-cost control for a wide variety of turbine, engine, and compressor applications. This control is designed to integrate into the modern plant architecture through the use of Ethernet and fieldbus communication protocols. Four Ethernet ports and add-on fieldbus communication modules allow for the network flexibility and redundancy. The Atlas-II provides reliable and deterministic performance for key prime mover control functionality.

   




MicroNet™ and MicroNet™ Plus Controllers

The Woodward MicroNet™ and MicroNet™ Plus Controllers are state-of-the-art, programmable, digital controllers. They can be programmed to control any prime mover and its associated processes, as well as system sequencing, high speed system monitoring, surge control, vibration monitoring and station control. The MicroNet™ digital control is available in both simplex and triple modular redundant (TMR) configurations. The MicroNet™ Plus is the next-generation MicroNet™, with flexibility that allows it to be configured with one or two CPUs; one or two power supplies; and simplex, duplex, or triplex I/O modules.

   




Servo Position Controller (SPC)

The Woodward Servo Position Controller (SPC) is a servo-valve driver that accepts a DeviceNet™ or 4?20 mA based position demand signal from a system controller, and accurately positions proportional or integrating servo-valves. The SPC has the required accuracy, responsiveness, and redundancy required for steam or gas turbine fuel valve control. For valve position sensing, the SPC accepts feedback signals from one or two (redundant) ac devices or one dc device. A Windows based software program is used to configure the SPC, adjust tunables, and monitor parameters via a personal computer. For ease of service, SPC configurations can be done while connected or disconnected to the unit. Once a configuration has been created, this program allows configurations to be uploaded and downloaded to other SPCs as desired.
