Description

The 9905/9907 series of the Woodward 2301A controls load sharing and speed of generators driven by diesel or gasoline engines, or steam or gas turbines. 

These power sources are referred to as “prime movers” throughout this manual.

The control is housed in a sheet-metal chassis and consists of a single printed circuit board. All potentiometers are accessible from the front of the chassis.

The 2301A provides control in either isochronous or droop mode.

The isochronous mode is used for constant prime mover speed with:

 Single-prime-mover operation;

 Two or more prime movers controlled by Woodward load sharing control systems on an isolated bus;

 Base loading against an infinite bus with the load controlled by an Automatic Power Transfer and Load (APTL) Control, an Import/Export Control, a Generator Loading Control, a Process Control, or another load-controlling accessory.

The droop mode is used for speed control as a function of load with:

 Single-prime-mover operation on an infinite bus or

 Parallel operation of two or more prime movers.

The following is an example of the typical hardware needed for the 2301A system controlling a single prime-mover and generator:

 A 2301A electronic control

 An external 20 to 40 Vdc power source for low-voltage models; 90 to 150 Vdc or 88 to 132 Vac for high-voltage models

 A proportional actuator to position the fuel-metering device 

 Current and potential transformers for measuring the load carried by the generator.

Features

 Actuators and self-cleaning valves are 4 times stronger with ‘sludge buster’ technology

 Patent-pending ‘Sludge Buster’ cleaning technology

 Advanced control algorithms and diagnostics

 Redundant optimum control configuration

 Same mounting base footprint as the CPC*

 Enhanced feature benefits:

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 dcs-sis.com 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.

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

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.
