    GE+ ACDC Installation and operation manual v11 9.2.1. Operation A: Connection mode. Informs about the connection: AC Independent/Parallel Bipolar (note that AC unipolar is not allowed) DC Independent/Parallel Unipolar DC Independent Bipolar (note that parallel bipolar is not allowed) The connection mode can only be modified by changing the switches in the front panel.

Once the user is in the third step, A part is for the Machine Control (Enable, Disable, Run, Ready and Reset) and B part is for the setpoints (the equipment will send the setpoints only in Run state).

Connect a RJ45 ethernet cable to the terminal X15. Modbus Serial Port. Uses RS485 or RS232 protocol. Connect a DB9 cable to the terminal X11.

  • Page 96: Alarm

    GE+ ACDC Installation and operation manual v11 9.2.2. Alarm In this tab, the alarms of each converter (active rectifier and inverter) are shown. When there is an alarm, the light turns into red. A: Active Rectifier alarms. B: Inverter alarms. C: Alarms history.

  • Page 97: Supervision

    GE+ ACDC Installation and operation manual v11 2. When the equipment has any alarm, it is reflected in the status. 3. Press Reset to reach the standby state (no alarms). 9.2.3. Supervision The supervision is an informative tab is where the user is able can see all the values of the converter.
  • Page 98 AC Operation This subtab allows the user to send all the AC parameters to control the Cinergia converter in AC mode: voltage setpoints, harmonics, phase angles, frequency, grid resistance and ramps. A: Part of the subtab to introduce all the parameters to be sent to the converter.
  • Page 99 GE+ ACDC Installation and operation manual v11 whereas the other columns are a percentage of the first column. From the 3 until the 11 harmonic, the percentage can go from 0% to 100% (0 to ±1) whereas 13 and 15 can reach 50% (0 to ±0.5).
  • Page 100 GE+ ACDC Installation and operation manual v11 AC Faults Before introducing any fault to the emulated grid, some grid must be created and there are two ways to do so: from the “AC Operation” tab (chapter 1.5.1) or the “AC Faults” tab (explained in this chapter).
  • Page 101 GE+ ACDC Installation and operation manual v11 C: Frequency Variation configurations. This fault makes the frequency grid to reach the introduced frequency according to the introduced ramps. The minimum and maximum frequency are the limits of the converter. If the duration of the fault (introduced in window G) is not long enough, the frequency will not reach the introduced one.
  • Page 102 GE+ ACDC Installation and operation manual v11 ramps for all three elements of each phase. The buttons Add Step and Config Step are explained at the point H of this chapter. G: General configurations of the fault. Set the duration of any fault and the starting angle referenced at the U channel.
  • Page 103 GE+ ACDC Installation and operation manual v11 A: This table shows all the values that refer to the configuration of the harmonics and it is distributed in the following way: The user can write the desired values on this table of the interface to create a harmonic file to be sent or saved as it is explained in the point E of this chapter.
  • Page 104 GE+ ACDC Installation and operation manual v11 C: This graph is behaving as the one before (B), but it draws the waveform showing how the harmonics will look like when the user uses an oscilloscope in the output (EUT side). D: Theoretical values are very useful to know which is the maximum output voltage, as well as the peak, the crest factor and the total harmonic distortion (THD).

  • Page 106 GE+ ACDC Installation and operation manual v11 9.2.5. DC DC Unipolar This subtab allows the user to send all the DC parameters to control the Cinergia converter in unipolar connection: current, power, impedance, voltage setpoints, virtual resistances and limits. Please read the Operation Modes document to know more about how to connect the equipment in unipolar.
  • Page 107 GE+ ACDC Installation and operation manual v11 All setpoints windows have the actual value right beside them. In this way, the user can know it without being necessary the supervision tab. 5. Set the resistance value to create a voltage drop. It is configurable for each channel and for independent and parallel mode.
  • Page 108 DC Bipolar This subtab allows the user to send all the DC parameters to control the Cinergia converter in bipolar connection: current, power, impedance, voltage setpoints, virtual resistances and limits. Please read the Operation Modes document to know more about how to connect the equipment in bipolar.
  • Page 109 GE+ ACDC Installation and operation manual v11 3. Set the impedance setpoints to be sent and its ramp. The allowed maximum and minimum values are 1000 and 0.8 Ω. The ramps go from 0 to 1000 Ω /ms. The user must calculate the appropriate value or resistance to get the desired current.
  • Page 110 GE+ ACDC Installation and operation manual v11 Once the limits are ready, press Send Limits. The button Refresh Limits will show in the windows the limits that the equipment has in that moment. When the converter is switched off and on again, these limits will be erased and substituted for the factory ones.

Voltage setpoints configuration where the user can introduce values for the global configuration (parallel), channel U, V and W and the ramp. 2. Current setpoints configuration where the user can introduce values for the global configuration (parallel), channel U, V and W and the ramp.

  • Page 113: Limits

    GE+ ACDC Installation and operation manual v11 9.2.6. Limits The user can define the limits of the equipment in this tab. The converter has its own factory limits, but it is possible to introduce new ones. The condition for these new limits is that they must be lower (in case of maximum limits) or higher (in case of minimum limits) than the factory ones, otherwise the equipment will introduce the factory limits.
  • Page 114 GE+ ACDC Installation and operation manual v11 2. Current limits. The user can set the maximum and minimum limits for each phase. These current limits are used in current mode (positive and negative) and in power mode (positive but not negative). 3.
  • Page 115 GE+ ACDC Installation and operation manual v11 DC Limits The interface will freeze or unfreeze (illuminate) the available parts where the user can introduce the parameters depending on the connection mode (parallel or independent). A: Voltage and current limits section. 5.
  • Page 116 GE+ ACDC Installation and operation manual v11 Each part (A, B and C) has two different buttons explained in the following lines. It is important that, for example, voltage limits must be sent, the buttons to use are the ones in the A part.

  • Page 117: Alarms Configuration

    GE+ ACDC Installation and operation manual v11 When the converter is switched off and on again, these limits will be erased and substituted for the factory ones. It is possible to save limits in the equipment in the EEPROM memory, but a password is required 9.2.7.
  • Page 118 GE+ ACDC Installation and operation manual v11 o Default Values. The user can define default values that will remember the equipment as long as it is switched on and lower than the Factory Values. o Factory Values. The equipment has its own factory values depending on the rated power.
