The amount of droop can be calculated using the formula.
Droop engine gensets which are set to 50 Hz operation at full load, need to have the engine no load governed speed adjusted to:
51.5 Hz (1545 RPM) for 3 % Speed droop 52.5 Hz (1575 RPM) for 5 % Speed droop
If the rated kW is not available, use the available kW to get the engine speed, as computed by the formula : Available kW load
S = NLS – ———————— x (NLS - FLS) (Rated kW load)
Where,
S = Speed at available load
NLS = No load speed (Same as high idle speed) FLS = Full load speed
(Rated speed normally 1500 RPM) Note :

The ‘Frequency adjust’ can be effected through ‘Speed Raise’ to ‘Speed Lower’ Inputs, or through ‘Speed bias Input’ one of these sources can be selected through PC Based tool settable trim.

Two switch input contacts called as “Speed Raise”
and “Speed Lower” are provided on the Connector B to adjust the generator set frequency. The frequency is adjusted within +/- 4 Hz of rated operating frequency.
The customer can implement the frequency adjust feature by connecting the speed Raise / speed Lower push buttons on the Connector B to (+) 24 Volts.
The engine speed will increase or decrease at a pre programmed rate depending upon the switch selected. The Raise / Lower ramp rate can be programmed through the service tool as shown in the enclosed figure..

An alternate frequency input is provided for selection between one of the two generator set frequency settings (50 Hz or 60 Hz).
This feature can be set through the service tool as shown in the enclosed figure.
Note : Note :Note :
Note :Note : The alternate frequency selection feature is only enabled for engines rated for dual speed operation. For engines rated for single speed operation, the alternate frequency input is non operational and no service tool related settings need to be made.
If the frequency selection using the alternate frequency input changes for dual speed engine operation while the engine is running, the selected frequency setting will not take effect until the engine is shut down and restarted.
The frequency adjust feature using Speed Raise / Speed Lower inputs is ineffective for dual speed operation.
All software calibrations in the ECP-G shipped out of the factory have a default setting of 50 Hz ONLY operation.
Separate software calibration(s) needs to be “downloaded”
into the controller if the genset is to be operated @ 60 Hz ONLY or 50 Hz / 60Hz (Dual speed operation).
