Standard and Custom Digital Controls for Steam Turbines

The 505XT controller is designed to operate single valve, or single extraction/admission industrial steam turbines of all sizes and applications. This steam turbine controller includes specifically designed algorithms and logic to start, stop, control, and protect industrial steam turbines or turboexpanders, driving generators, compressors, pumps, or industrial fans.

The Woodward Peak200 digital control is designed to control steam turbines driving small pumps, compressors & fans based on the proven 505 platform. Features include integrated operator control panel/HMI, communications networks, expandable I/O and more.

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.

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).

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.

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).

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.

The Woodward Servo Position Controller (SPC) is a servo-valve driver that accepts a DeviceNet™ or 420 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.
