Woodward 2301E-J Microcomputer-Based Digital Controller

Functions

The 2301E-J has speed control, load control, equal speed/no load transfer, and fuel limiter functions.

Speed Control Function

- Rated speed range of 400-3600 rpm

- Constant speed speed control

- kW Reduced speed control

- Simple derating control is selectable (when selected, the load control function is not available)

- Idling/rated speed switching by discrete input signal

- Speed reference up/down using discrete input signals

- Fast synchronisation using analogue speed bias signal from synchroniser

- (Optional) Speed reference manipulation function using remote analogue signal

- Single point control gain setting (optional)

- A control gain curve consisting of 5 points with 4 ramps can be mapped to the engine to change gain under various operating conditions.

- Dual power function to switch control power according to engine load

Load control function

- Automatic isochronous load sharing function (including soft load handling from the generator breaker close to the start of automatic load sharing)

- kW Initial loading function after the generator breaker is closed in down operation.

- Automatic soft unloading function (generator breaker open output signal is unloading trip level)

- Asynchronous base load operation (optional remote load setting function)

- kW descending operation (remote load setting function via remote speed setting signal)

- Generator load operation using the speed down function. (The load control function is not applicable to speed drop operation).

Fuel Limiter Function

The 2301E-J has the following six fuel limiter functions:

- Start-up fuel limiter (including lower limit, upper limit, and slope from lower limit to upper limit)

- Maximum Fuel Limiter

- Torque limiter (5 points and 4 ramps)

- Boost Fuel Limiter (optional) (5 points and 4 ramps)

- Discrete Input Fuel Limiter

- Fuel limit is cancelled by discrete input signal

Equal Speed/Idle Switching Function

- Isochronous/idle switching by discrete input signal

- Trouble-free switching from isochronous operation to kW down operation

- Load ramp from kW load drop level when connected in parallel with the utility to isochronous load sharing level when connected in parallel

Isochronous base load operation

- Base load set point raise/lower function with discrete inputs

- Generator kW load remains constant regardless of utility frequency

- Base load set point raised/lowered by analogue remote signal
