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 DSEA108 Configuration Suite PC Software Manual. Start the generating set and observe the feedback voltage using the SCADA screen and the voltmeter.

Setup Procedure 4.3.2 STABILITY SETTINGS The following subsections detail the procedure for setting up the Proportional, Integral, and Derivative stability settings for optimal AVR load acceptance and operation. 4.3.2.1 PROPORTIONAL NOTE: If an oscilloscope is not available, the voltmeter and SCADA screen are used solely.
Setup Procedure 4.3.2.3 VOLTAGE SET POINT STEP The Voltage Set Point Step feature allows the configured stability settings to be tested, without the use of a load bank. The voltage Set Point is increased and decreased by a pre- defined percentage, at the set interval for a set number of cycles.
Setup Procedure 4.3.2.4 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.
Setup Procedure 4.3.2.5 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.
Setup Procedure 4.3.3 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.
Setup Procedure 4.3.3.2 PRE-DEFINED DROOP SETUP NOTE: When completing a pre-defined droop setup, the DSEA108 must be wired as shown to match the selected topology in Configuration Suite. Failure to do so causes erroneous droop operation. The pre-defined droop setup procedure is...
Setup Procedure 4.3.3.3 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.
Setup Procedure 4.3.4.2 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.
Setup Procedure 4.4 FINALISING SETUP NOTE: For further details of module configuration, refer to DSE Publication: 057-271 DSEA108 Configuration Suite PC Software Manual. 4.4.1 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.
Setup Procedure 4.4.1.1 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.
4.4.3 ALTERNATE FREQUENCY RANGE NOTE: The Alternate Frequency Range DIP switch is not functional when the Auto Frequency Detection function is enabled. For further details of module configuration, refer to DSE Publication: 057-271 DSEA108 Configuration Suite PC Software Manual. DIP Switch Function...
Setup Procedure 4.5 FINAL CHECK Start the generator set and check that it reaches the set voltage and is stable. Test with various step loads within the limits of the generator and check that the voltage is stable with good transient response. Increase to full load and check that the alternator output remains at the Set Point and is stable.

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.
UNDER FREQUENCY ROLL OFF (UFRO) NOTE: For further details of module configuration, refer to DSE Publication: 057-271 DSEA108 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. This reduces the alternator output voltage which in turn, reduces the load on the generator.
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 DSEA108 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.
Operation 5.1.2 DIP SWITCHES DIP switches are used to select between different configurations within the device. Each configuration is adjusted using DSE Configuration Suite PC Software.

5.3 EXTERNAL AC VOLTAGE BIAS NOTE: Voltage adjust range is configured using DSE Configuration Suite PC Software. For further details, refer to DSE Publication: 057-271 DSEA108 Configuration Suite PC Software Manual. Two external bias inputs are provided to allow remote adjustment of the alternator output.
6.2 LOSS OF FEEDBACK NOTE: Loss of Feedback Delay is configured using DSE Configuration Suite PC Software. For further details, refer to DSE Publication: 057-271 DSEA108 Configuration Suite PC Software Manual. During normal running operation the main generator output is monitored. If this drops below 5% of the Voltage Set Point for the duration of the Loss of Feedback Delay time, the Loss of Feedback alarm occurs.
