The 505DR® Dual Redundant Turbine Controller is a state-of-the-art digital control platform designed to reliably control and protect single-valve and single-pump steam turbines.

The benefits of dual redundancy maximise turbine reliability and availability.

Redundancy is managed at the operating system level using Woodward’s RTN (Real Time Network), allowing ultra-fast switching and ‘bufferless’ transitions.

The controller utilises the same unique PID architecture as the proven 505XT, making it the ideal controller for controlling speed, load,

parameters such as pumping collector pressure, exhaust collector pressure or connection line power. The dual redundant version inherits features such as the Opti-Tune self-tuning PID and ratio limiter.

The controller includes the following turbine protection features to ensure that the turbine and its driven loads (compressors, pumps, generators) operate within design limits:

– 3 critical speed avoidance bands

– Overspeed prediction and shutdown protection

– Configurable under- or over-pressure shutdown logic

– Minimum and maximum speed and load settings

– Maximum low-pressure stage overpressure limitation

– Minimum high pressure stage flow limiting

Ethernet and serial communications allow for easy integration into plant controls or process control systems.

The 505DR can be configured with an optional integrated user interface, including an 8.4-inch multi-language graphical display.

Description

Like the MicroNet Plus, the 505XT system designates one controller as the System Controller (Syscon), actively controlling the fan.

The second device is configured as a www.cniacs.com backup. The system automatically evaluates the health of the Syscon and initiates a fast switchover in the event of a failure.

Switchover can also be initiated manually. The system closely synchronises the Syscon’s software status and memory with the backup, ensuring that the control output remains stable and does not affect turbine operation (a true ‘bufferless’ switchover).

If the optional HMI version is selected, the display and keypad are redundant (input from either keypad will command Syscon, and the display can be independently selected to show different screens.

For example, one screen can display speed and speed settings, and another can display a steam map.

Woodward’s optional RemoteView programme allows remote monitoring from any networked PC.

The programme can be used either with the rear panel mounted version (as the main HMI) or as an additional remote monitor to the HMI version.

The optional FTM (Field Terminal Module) allows easy multiplexing of redundant signals and facilitates fast installation and commissioning.

Part 8271-468 Generator Loading Control from Woodward.

It runs on 115/230 volt AC power and has a beige case. This unit is primarily used in commercial applications.

When used in conjunction with the Woodward Load Sharing and Speed Control System, it allows you to adjust the electrical load being carried by the generator set.

Product Description

The standard commercial features of the Generator Load Control Unit 8271-468 have been programmed into the unit.

This allows the unit to control user-selected electrical load adjustment of the generator set.

Operation www.cniacs.com and adjustment of the 8271-468 to the desired specifications is highly dependent on the unit’s use of the power system.

It can be used with an isolated power system or with a local system connected in parallel with an infinite bus.

In an isolated system, the 8271-468 generator load control is used in conjunction with each load sharing and speed control.

The 8271-468 is wired in parallel with these two units to detect generator loads.

The output of this unit is designed to bias the line voltage to control a portion of the total system load.

If connected in parallel to an infinite bus, the voltage at the generator load control device load signal test socket should be measured when the unit is fully loaded.

In an isochronous parallel application, Generator Load Control Part No. 8271-468 regulates power while the utility maintains frequency.

The advantage of this control system over standard parallel buck operation is that, when separated from the utility, the

The now isolated busbar is automatically under isochronous speed control, eliminating the need for the operator to readjust the speed setting.

Within Woodward Equipment’s line of generator controls, the 8271-468 has the widest market availability compared to other components.

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.

FTI Advantages.

Fast, consistent fuel combustion

Improved engine efficiency

Reduced exhaust emissions

No hot running and good detonation margins

Longer life

Customisable design

Objectives achieved: Improved engine efficiencyContinuous fuel ignition – More complete fuel combustionFaster combustion – Just in Time Departure Point (ATDC) for improved combustion efficiencyImproved combustion stability

j-gap with FIT.

FTI’s patented pre-combustion chamber combustion technology 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.
