The 505 and 505E microprocessor-based controls

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.

The ProTech 203 Overspeed Protection System

The ProTech 203 Overspeed Protection System monitors three individual magnetic pickups (MPUs) to provide overspeed protection for steam and gas turbines and other prime movers. The system replaces mechanical overspeed devices, especially in high-speed applications (above 10,000 rpm) when a mechanical overspeed device becomes unreliable.

2301A Load Sharing and Speed Controls

The 2301A Load Sharing and Speed Controls are designed for use in electric generator systems where multi-unit load sharing is desired. 2301A controls may be used with diesel, gas or gasoline engines, or steam or gas turbines. Controls are available for applications requiring droop and/or isochronous speed control; in forward- or reverse-acting models; for single or tandem actuator installations; with accelerating or decelerating ramps; and in several speed ranges. Automatic, adjustable start fuel limiting regulates the maximum fuel setting while the engine is starting. This helps decrease pollution and engine wear. Each 2301A control has a self-contained load sensor. Most models provide a 0–200 mA output signal; 0–20 mA output is available for special applications. The output signal is proportional to the fuel setting needed to attain the desired speed/load. Position feedback from the actuator is not required.

2301D Programable Load Sharing and Speed Control

The 2301D and 2301D-EC Digital Load Sharing and Speed Controls are used in electric generator systems for which load sharing is desired. They can be used with diesel or gas engines, or steam or gas turbines. The control utilizes a digital based speed control and provides a single serial port for PC communications. The digital design eliminates the use of potentiometers for tuning and load control.

The 2301D-ST Programable Steam Control

The 2301D-ST is a microprocessor based control with integral application software designed for single-valve steam turbine applications. 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. The application software is field configurable, allowing it to be configured and modified to meet site-specific requirements.

723 Plus Digital Control

The 723 Plus Digital Control manages and controls reciprocating engines (gas, diesel, or dual fuel) used in power generation, marine propulsion, and gas compression/distribution. The control may also be used in cogeneration, power transmission/distribution, process management, pipeline pump stations, utility power generation, emergency standby power, and remote control station operation. The 723 Plus provides state-of-the-art control for new and retrofit situations.
