Description

The MicroNet TMR® control platform features a ruggedized rackmount chassis with in-line replaceable I/O modules and triple modular architecture for 99.999% availability.

This triple modular redundancy-based system consists of three independent cores (A, B, and C) housed in the platform’s compact chassis.

Each core section includes its own CPU, CPU power supply, and up to four I/O modules, which can be used for simplex I/O, redundant I/O, triple redundant I/O, or any combination of redundancy.

I/O can be expanded via a system expansion chassis or the ruggedized LinkNet HT Distributed I/O.

The platform’s high-density modules and integrated application software reduce troubleshooting time by providing first-out indication of monitored system events.

These specialized modules can time stamp discrete events in 1 millisecond and analog events in 5 milliseconds.

The MicroNet TMR® utilizes two power supplies, each supplying power to the controller from a separate power source. Within each power supply are three independent power converters, one each for the CPU and I/O sections.

This triple power supply structure provides maximum protection against single or multiple points of hardware failure.

The controller’s dedicated TMR® Discrete I/O Module is designed for critical discrete circuits.

The module accepts discrete inputs and distributes them to each individual core section, as well as outputs relay contacts to drive discrete application logic.

The module’s special TMR® outputs utilize a six-relay configuration and integrated potential fault detection logic that allows any one or two relays to fail without affecting the integrity of the output contacts.

This configuration allows routine relay testing and in-circuit repair without compromising output or system integrity.

Designed from the ground up as a turbine control system, the MicroNet TMR® controller’s actuator drive module is available with the use of single or dual redundant coils,

Proportional or integral turbine valve servos with AC or DC feedback position sensors using single or dual redundant coils.

The MicroNet TMR® controller can accommodate any combination of Woodward MicroNet I/O modules and LinkNet HT distributed I/O to provide maximum application flexibility.

 Magnetic pickups (MPUs) and proximity probes

 Discrete I/O

 Analog inputs/outputs

 Thermocouple inputs

 Resistance Temperature Devices (RTD)

Description

APECS™ 0175 linear actuators deliver precise positioning and form the foundation of a full electronic governing system.

Many of the moving parts normally associated with electric actuators are eliminated, prolonging the MTBF (mean time between failure).

The actuator design employs the principle of variable reluctance for consistent force over the entire stroke.

This simple design of a proportional electric linear actuator utilizes a linear armature whose magnetic force is proportional to the input current to the coil.

These actuators are easy to install by mounting near the fuel system with a direct connection to the fuel control rod or level.

In most installations, the normal rotary-torotary connection www.abb-drive.com is eliminated, resulting in a more trouble-free and accurate control system.

APECS 0175 actuators are suitable for installation on diesel, gasoline, or natural gas engines with fuel system force requirements of less than 4.0 pounds (17.8 N) of force.

Woodward also manufactures 0175 actuators integral to the engine block or fuel pump.

The CPC-DX 10 bar, 2 zone, redundant, has an enhanced dynamic dual transmission current-to-pressure converter skid for on-line (automatic and manual switching) service capability for uninterrupted operation to position single acting turbine valve servos in critical applications.

Features and Functions

Woodward’s redundant skid-mounted current-to-pressure converter (CPC-DX) is an electro-hydraulic pressure-regulating control valve for positioning single-acting steam turbine valve servos/actuators.

The redundant version of the CPC-DX accepts a 4-20 mA pressure demand signal and accurately controls oil pressure to precisely position the single-acting steam turbine speed control valve.

Accurate and stable steam valve control is directly related to increased steam turbine speed and load control and reduced mechanical wear on the system.

The integrated design of the CPC-DX redundant version allows for www.abb-drive.com the cost-effective purchase and installation of a hydraulic assembly that provides all the isolation and support benefits of a fully segmented current-to-pressure converter.

Manual isolation valves are included in the package, allowing the user to easily repair or replace each individual current-to-pressure converter.

Both automatic and manual transfer logic is available for this skid block assembly, depending on the design of the system.

The skid block’s automatic transfer logic simplifies system design because it does not require external relay/switching logic to operate.

This minimises wiring at the converter-to-converter and control-to-converter interfaces.

The CPC’s configurable alarm/shutdown logic allows the user to easily configure which system conditions force an automatic transfer from the master CPC to the slave CPC.

The manual transfer feature is also available for systems where the user wishes to switch between pressure converters via external logic or manual switching.

The master select discrete input is used to allow the user to easily and quickly select the desired control CPC.

An integrated oil pressure gauge allows the user to visualise which converter is in control and verify the skid’s output oil collector pressure level.

Discrete output relay contacts can also be connected to system indications (lights, lamps, plant DCS) to assist in system operating condition monitoring.

Pre-ignition chamber spark plugs for fast, consistent ignition of thin-burning natural gas engines

Woodward’s Fast Turbulent Ignition (FTI) provides fast, consistent ignition of gaseous fuel mixtures in internal combustion engines.

It results in more uniform and complete fuel combustion, increased engine efficiency and improved exhaust emissions.

The FTI is designed to optimise the operation of high-performance, high BMEP, lean-burn natural gas engines used in stationary power applications.

Features and Functions

Large bore engines using dilute gas fuel mixtures typically experience slower fuel burn rates and incomplete combustion.

These conditions reduce combustion efficiency and result in problematic exhaust emissions.

Typical J-gap spark plugs attempt to address these performance issues by increasing spark energy, which can shorten spark plug life.

To counteract the shortened spark plug life, J-gap manufacturers often increase the electrode area, which can have a detrimental effect on the ignition spark.

This has a “quenching” effect on the ignition spark, which increases combustion variability;

Or they use precious metals, which increase manufacturing complexity and reduce plug durability.

FTI’s unique, patented design provides consistent ignition without the need for a high-energy ignition system, reducing the need for precious metal electrodes for long life.

It can also be customised to meet specific engine combustion requirements.

j-gap with FIT.

FTI’s patented pre-combustion chamber combustion technology www.abb-drive.com improves combustion start-up with J-gap and conventional pre-combustion chamber spark plugs.

J-gap1 Typical J-gap spark plugs have a spherical flame front that burns slowly as it passes through the combustion chamber. This type of flame front is susceptible to high turbulence in the combustion chamber, which can quench or even blow out the spark, again increasing ignition variability. In addition, smaller spark surfaces corrode more quickly, shortening the life of the spark plug.

FTI addresses these issues by using a separate flame core for ignition. The multi-jet flame front from the FTI igniter creates its own combustion chamber turbulence. This self-generated turbulence adds to existing chamber turbulence while being highly resistant to other chamber turbulence that promotes rapid flame growth throughout the fuel mixture.
