Woodward 2301E-J Microcomputer-Based Digital Controller
OVERVIEW
The 2301E-J is a microcomputer based digital controller for engine genset control with automatic load sharing.
The controller is designed to control medium to high speed diesel engines or medium to high speed gas engines.
Control speed range (for medium to high speed engines): 400-3600 rpm.
Similar in function to the 2301A LSSC, the 2301E-J is Woodward’s traditional analogue controller plus a DRU (Digital Reference Unit) with soft load/unload.
The 2301E-J also has the same features as the 2301D.
While the engine is operating, the 2301E-J can switch its operating mode from isochronous to sag and vice versa without buffering.
The 2301E-J can be switched to the 2301D by using the same function as the 2301 LSSC, the 2301A LSSC, the 2301D LSSC, and the 721DSC with Automatic Load Sharing,
723DSC with automatic load sharing, or other Woodward Electric controls with load sharing capability to operate in automatic load sharing mode.
In conjunction with an external inlet/outlet controller, the 2301E-J can control the inlet/outlet power to the mains (i.e., commercial bus) by simulating a remote speed setting signal (optional feature).
The 2301E-J can operate in isochronous mode, isochronous base load mode, kilowatt drop mode, normal speed drop mode, and mains parallel operation mode with GCP/EGCP.
In Isochronous operation mode, the 2301E-J can perform the following operations
– Parallel operation with multiple engine-generator sets connected to the bus via automatic load sharing functions (including soft load and soft unload).
– Base load operation in isochronous mode. (The load level can be preset or manually adjusted to the desired level using discrete or analogue inputs).
– Single engine generator operation. (Speed reference is manually adjusted to the desired level via discrete or analogue inputs).
In kW down operation, the 2301E-J can perform the following operations:
– Run in parallel with the mains. (Load level or speed reference preset or manually adjusted to the desired level via discrete or analogue inputs).
– Parallel operation with other engine generator sets. (Manual adjustment of the speed reference to the desired level via discrete or analogue inputs).
– Single engine genset operation. (Manual adjustment of the speed reference to the desired level via discrete or analogue inputs).
– In reduced speed operation, the 2301E-J can perform the following operations:
– Run in parallel with the power supply. (Manually adjust the load level or RPM reference to the desired level via the discrete inputs or analogue inputs).
– Operate in parallel with other engine generator sets. (Manually adjust the load level to the desired level via the discrete inputs or analogue inputs).
– Single engine genset operation. (Manually adjust the speed reference to the desired level via the discrete or analogue inputs).
