Woodward Electronic Controls and Software for Gas Engines

2300G Gas Engine Control
The Woodward 2300G is a microprocessor-based hardware platform that is programmed for a specific application. The control can be used to provide speed and load control functions for reciprocating power generation engines. The control consists of a single printed circuit board that is housed in a sheet metal enclosure. Both ordinary and hazardous location versions are available. The unit is intended for bulkhead mounting, and spring-loaded terminal blocks are provided for termination of field wiring. The Woodward 2300G is powered from 24 Vdc. Integral load sensor and load sharing capabilities are available that allow the control to be configured for a variety of power generation applications. Isochronous load sharing, kW droop, and base load operation can be provided.

EGS Control System for Industrial Spark-Ignited Engines
Woodward's EGS control system controls industrial gas engines used in power generation, pumping, and other stationary applications ranging from 300 kW to 2000 kW (400-2700 hp). The highly accurate, closed-loop control system helps customers meet regulated emission levels, while maintaining engine performance over a very large range of fuel qualities.

723PLUS
The Woodward 723PLUS 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 Woodward 723PLUS provides state-of-the-art control for new and retrofit situations.

723PLUS Compressor Performance Control
The Woodward 723PLUS Compressor Performance Control, based on Woodward's powerful 723PLUS/828 digital control platform, controls the speed, air/fuel ratio, and ignition timing of reciprocating engines in variable speed/load applications. The control includes inputs for two speed sensors (MPU or proximity) with firing torsional filters, for monitoring engine and turbocharger speed (or for redundant engine speed sensing), a notch filter to attenuate the effect of flexible coupling torsionals, a remote speed setting input, and inputs for air manifold pressure, fuel gas header pressure, and air manifold temperature with 3D curves for precisely mapping air/fuel ratio and ignition timing settings. Discrete raise/lower inputs are provided to adjust air manifold pressure and engine speed settings.

733 Digital Control
The Woodward 733 Digital Control manages and controls reciprocating engines (gas, diesel, or dual fuel) used in power generation, marine propulsion, locomotive and industrial engine, and process markets. The Woodward 733 has been specifically designed to enable it to be mounted directly on the engine, withstanding the high temperature and vibration environment. The Woodward 733 can also be mounted inside control cabinets if required.The Woodward 733 is available as a standalone speed control with functions and configuration similar to other Woodward digital controls such as Woodward 723 (including plug-and-play network connectivity to the Woodward ProAct™ Digital Actuator family for an all-electric governing solution that can be engine mounted), and it is available as the main control unit within an engine management system. The control is designed for network connectivity to other Woodward or customer-selected devices, such as I/O modules (remote or integrated within the Woodward 733 package), actuators, ignition controls, air/exhaust and fuel flow control valves, power management controls, and EFI solenoid drivers. It may be programmed to perform all engine functions such as speed, air and fuel control, monitoring, alarms, engine protection and sequencing.

In-Pulse
The Woodward In-Pulse system has been developed to control a range of Woodward electrical low-pressure gas admission valves and electric-hydraulic high-pressure rail valves. These valves provide a means of injecting fuel or other fluids into engines operating within a speed range of 1 to 2100 rpm (range depends on the valve being driven). Plate type solenoid operated gas admission valves (SOGAVs) are suitable for in-manifold injection only, whereas the rail valve provides actuation of both in-cylinder and in-manifold type injection devices.

In-Pulse II
The Woodward In-Pulse II fuel injection control manages and controls electronically fuel injected (EFI) reciprocating engines (gas, diesel, or dual fuel) used in power generation, marine propulsion, locomotive and industrial engine, and process markets. The Woodward In-Pulse II manages the core fuel system and injection events for many EFI fuel systems, including electronic unit injectors and pumps (EUI/EUP), common rail systems (C-R), SOGAV™ Solenoid Operated Gas Admission Valves, micro pilot injection systems, and electronic rail valves (ERV). The Woodward In-Pulse II can mount directly on the engine, withstanding the high temperature and vibration environment. The Woodward In-Pulse II can also be mounted inside nearby control cabinets if required.

Atlas-II Control Platform
The Woodward 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 necessary for today's communication architectures. 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. Less critical control functionality can be added into the Woodward Atlas-II through the use of free-time programming structures and distributed I/O. The Woodward Atlas-II programmable control is designed specifically for prime mover control applications such as gas turbines, compressor control and protection,·gas and diesel engines, steam turbines, hydro turbines.

SG 2D Digital Speed Governor
The Woodward SG 2D is designed as a universal digital speed governor for combustion engines. It is configured via a PC using a direct configuration cable (DPC) and a PC software tool. Tuning of the Woodward SG 2D can also be carried out with the control's pushbuttons and four-digit display. The Woodward SG 2D is designed to drive a variety of electric actuators such as solenoid style (rotary or linear) or a smart actuator via a PWM control signal. The Woodward SG 2D has adjustable overspeed protection, adjustable maximum fuel limit, and adjustable actuator droop.

IKD 1 Digital I/O Expansion Board
The Woodward IKD 1 is an "Intelligent Terminal" or "Extension Board". It allows an additional 8 discrete inputs and 8 relay outputs to be connected, via CAN bus, to other Woodward products such as the Woodward GCP-30 Series controller. Each input can be assigned a name, alarm class, NO/NC configuration and time delay. The name and class are then displayed on the digital readout panel on the controller face. The Woodward IKD 1 output relays are controlled over the CAN bus connection from the main controller. Configuration for the Woodward IKD 1 is also accomplished from the main controller by a code entered via the controllers relay manager.

Watch Window Standard PC Software
