Page 18: Setup Procedure
Doing so results in loss of voltage control and potential damage to the generator. NOTE: For further details of module configuration, refer to DSE Publication: 057-271 DSEA106 MKII Configuration Suite PC Software Manual. The engine must be commissioned as far as possible before this procedure is carried out, in particular the governor must be setup to produce stable speed control at 1500 RPM / 1800 RPM. - Page 19 Setup Procedure Using DSE Configuration Suite PC Software, select the 90 V to 300 V appropriate voltage menu Low Voltage Range (for 90 V to 300 V systems) or High Voltage Range (for 180 V to 600 V systems). This voltage refers to the voltage applied to the AVR L and N (L2) terminals (the sensing voltage).
- Page 20 Setup Procedure Open the selected Stability Configuration page. Preset Enable Ensure the Proportional and Integral Preset remains ‘checked’ Enable options are checked, and set the Preset Range of both to 100 %. Preset Enable remains ‘checked’ Set the Derivative Set Point to 0. Set the Maximum Duty Cycle to 100 %.
- Page 21 Setup Procedure Using DSE Configuration Suite PC Software, connect SCADA and select the Commissioning Screen display. Set the Proportional preset on the AVR to approximately 10. Set the Integral preset on the AVR between 1 and 2. Ensure the derivative value is 0, and the Output Duty Cycle is 100 % with the engine not running.

NOTE: Do not apply load to the set until instructed during the following procedure. NOTE: For further details of module configuration, refer to DSE Publication: 057-271 DSEA106 MKII Configuration Suite PC Software Manual. Start the generating set and observe the feedback voltage using the SCADA screen and the voltmeter. -

Page 24: Proportional
Setup Procedure The following subsections details the procedure for calibrating the Proportional, Integral, and Derivative settings for optimal generator load acceptance and operation. Wherever possible, a load bank is to be used to ensure stable voltage control during different loading conditions. If a load bank is not available, the Voltage Set Point Step function is used to emulate load step changes. -
Page 25: Derivative
Setup Procedure 4.1.1.3 DERIVATIVE NOTE: Proceed below only after setting both Proportional and Integral. NOTE: If an oscilloscope is not available, the voltmeter and SCADA screen are used solely. This does not show rapid oscillation of the voltage output and hence does not provide the optimum setup environment. - Page 26 Setup Procedure The AVR’s response to these Voltage Set Point Step changes indicate how well the current stability settings handle load changes, and what further adjustments may be required. Example oscilloscope traces of the AVR’s ‘transient response’ to Voltage Set Point Step changes are shown below: Voltage Set Point Steady State...
-
Page 27: Soft Start Ramp
Setup Procedure 4.1.1.5 SOFT START RAMP Once the stability settings have been completed, the Soft Start Ramp values can be set. The Ramp Start Point value determines the percentage of the configured voltage Set Point at which the Soft Start Ramp takes effect. If a voltage spike at a value below the voltage Set Point is shown on start up, decrease this value. -
Page 28: Droop Setting
Setup Procedure DROOP SETTING NOTE: Proceed with Droop setting only after the AVR has been correctly stabilised by following the Stability Settings section first. Quadrature Droop monitors the reactive power provided by the generator to the load and is used to provide kvar sharing (reactive load sharing) between generators. -
Page 29: Obtaining And Configuring Ct Phase Shift
Setup Procedure 4.1.1.7 OBTAINING AND CONFIGURING CT PHASE SHIFT NOTE: It is very important that Droop Initial Setup procedure is followed before continuing. To account for the choices made for the CT, its location and which phases are used for voltage sensing, Offset Angle must be configured correctly. -
Page 30: External Bias Setting
Setup Procedure EXTERNAL BIAS SETTING NOTE: Proceed with External Bias Setting only after the AVR has been correctly stabilised by following the Stability Settings section first. 4.1.1.9 EXTERNAL POTENTIOMETER NOTE: The external potentiometer is designed for manual adjustment of the output voltage. -
Page 31: Dc Voltage Input
Setup Procedure 4.1.1.10 DC VOLTAGE INPUT NOTE: The DC Voltage Input is designed for automatic voltage matching or kvar sharing. For manual adjustment, use the External Potentiometer input instead. NOTE: Where both (External Potentiometer and DC Voltage Input) are used simultaneously, both inputs are summed to determine the output voltage. -
Page 32: Finalising Setup
Setup Procedure FINALISING SETUP NOTE: For further details of module configuration, refer to DSE Publication: 057-271 DSEA106 MKII Configuration Suite PC Software Manual. PRESETS WARNING!: Use only a suitable insulated potentiometer (preset) adjustment tool. Presets are the adjusters fitted on the AVR and may be disabled if end user adjustment is not required. -
Page 33: Voltage Preset
Setup Procedure 4.1.1.11 VOLTAGE PRESET If the voltage preset is required to be active, check the Preset Enable parameter in the configuration and set the Anticlockwise Limit of Preset and Clockwise Limit of Preset to give the desired control span. Write the configuration to the AVR. -

Page 35: Final Check
Setup Procedure FINAL CHECK Start the generator set and check that it reaches the set voltage and is stable.

Page 37: Presets
Operation PRESETS It is possible to disable the operation of the preset using DSE Configuration Suite PC Software in conjunction with DSE815 Interface. In this instance, the value of the disabled preset is fixed by the PC Software. 5.1.1.1 VOLTAGE SET POINT The Setting for the alternators output voltage. - Page 38 Operation Multiple Generators In a multiple generator system, the droop on the AVR is working to minimise the alternators kvar production. If the droop on each AVR is set identically, it balances the kvars between all the alternators as they each try to produce the minimum reactive power. This enables a basic form of reactive power (kvar) sharing between connected generators, providing each AVR is configured to provide the same amount of droop.

Page 39: Under Frequency Roll Off (Ufro)
UNDER FREQUENCY ROLL OFF (UFRO) NOTE: For further details of module configuration, refer to DSE Publication: 057-271 DSEA106 MKII Configuration Suite PC Software Manual. To help protect the alternator, output excitation is limited when generator output frequency is low, this is known as Under Frequency Roll Off. -
Page 40: Proportional
Adjusts the Proportional gain of the AVR output control. Turning the preset clockwise raises the Proportional gain. Should the generator output be different from the DSEA106 MKII Voltage Set Point, a jump in Excitation Output is made to correct the error. The amplitude of this jump is governed by the Proportional Gain. -
