WOODWARD  8290-184  EPG Electrically Powered Governor

Each Woodward Electrically Powered Governor (EPG) system includes three basic parts:  A magnetic pickup (MPU) which senses engine speed from an enginedriven gear.

● A speed control which receives the speed signal from the MPU, compares it 

● to a reference signal, and generates a control signal which the control sends to the actuator.  An actuator which receives the signal from the control and positions its 

● output shaft according to this signal. The output shaft is linked to the fuel control. There are two EPG models:  The isochronous speed control, which is available with start-fuel limit or dual

● dynamics;  The droop speed control, which includes a load sensor and provides droop

● control for generator sets. Different actuator sizes are available for different work output requirements. Models are available for either 12 or 24 volt systems.

Example 1: The generator set is a 60 Hz unit with an isolated load. If the desired droop is 5% and the generator set can be run at 100% load, then the speed at full load would be 57 Hz.

Example 2: It is again desired to set the droop of the same generator set to 5%, but this time the generator set cannot be run at 100% load. The generator set is therefore run at 50% load and the speed (in step 3) would be 58.5 Hz.

Example 3: The generator set is a 60 Hz unit that will be paralleled with an infinite bus. If the desired droop is 5% and the generator set can be run at 100% load, the speed at which the generator is run (in step 2) would be 63 Hz.

Note: In expensive AC to DC Battery chargers used for maintaining the battery charge allow moderate surges from the AC mains to couple to DC power: To protect the EPG a surge arrestor of at least the energy & voltage capability of a V47ZA7 MOV should be placed from battery minus to battery plus terminals.
