5. Intended use

This product is designed exclusively to regulate voltage at the low voltage level (400V L-L).

6. Description and Principle of Operation

The LVRSys™ regulator concept is based on a linear regulator. By coupling and uncoupling two transformers with a selected transfer ratio, the output voltage can be regulated in several (e.g. 9) steps. The maximum control range depends on the version (e.g. from ±6% up to ±20%).

The transformers are controlled by thyristors. The stages of the transformers are determined by the thyristors' switching settings.

Step Transformer 1.5% Transformer 4.5%

+6 % +1.5 % +4.5 %

+4.5 % 0 % +4.5 %

+3 % -1.5 % +4.5 %

+1.5 % +1.5 % 0 %

0 % 0 % 0 %

-1,5 % -1,5 % 0 %

-3 % +1.5 % -4.5 %

-4.5 %/ 0 % -4.5 %

-6 % -1.5 % -4.5 %

Table 6-1 Generation of the voltage levels in steps

The control signals for the thyristors are generated by driver circuits that switch them intelligently. By monitoring the magnetic flux in the transformers, the transformers can be switched without voltage dips, current increases or generating harmonics.

The step change required is output by the controller. The controller can determine the step based on the bus bar voltage or the output currents.

All three phases are regulated independently of one another. This helps improve the symmetry of the grids.

In the event of a failure the safety contactor activates automatically. This ensures that the transformers are shorted and as such the low-voltage grid will operate unregulated.

Table 6-2 Explanation of the abbreviations

Figure 6-2 Example of 3% voltage reduction

In the example shown in Figure 6-2, the output voltage is reduced by 3% compared with the input voltage. The transformer Trafo 1 (-4.5%) converts the primary voltage, which is switched by thyristors, in a negative direction and subtracts 10.35 V (4.5% of 230 V) from the output voltage. The transformer Trafo 2 (1.5%) converts the primary voltage in a positive direction and adds 3.45 V (1.5% of 230 V) to the output voltage.

In the example, the voltage value at the end of the cable would deviate from the regulator's voltage value by 100 A x 0.05 Ω = 5 V, at a current flow of 100 A.

When configuring the grid impedance, the regulator constantly calculates the voltage from the voltage value in the regulator + grid impedance x grid current.

Firmware update 11.13.1


Make sure the service switch is active before starting the update process.

Activating the service switch isolates the thyristors from the mains voltage and short-circuits the transformers. The control function is out of order. A secure update process can be started.

IEC 60870-5-104 11.14.3

The IEC 60870-5-104 is a communication protocol that communicates over the TCP/IP interface. The IEC Protocol has to be unlocked via a license. If this communication is required, contact the A. Eberle suppport team.

11.14.3.1 License IEC 60870-5-104 unlock

The licensce file will be transmitted by the A. Eberle Support Team and is linked to the serial number of the system.

Save License file on FAT32 formatted USB stick.

Connect USB stick to LVRSys™.

Select menu item License File.

Confirm with Yes.

IEC 60870-5-104 is unlocked.

11.14.3.2 CSV configuration of the IEC 60870-5-104 Slave

The LVRSys™ IEC 60870-5-104 Slave can be configurd by using a CSV file. When starting the system, the CSV file will be loaded and the IEC 60870-5-104 slave is then ready for use.

In the standard lvrsys_t104_target.csv all possible configurations are described. The desirec changes must be made directly in the file, using the following steps:

Get CSV-File lvrsys_t104_target.csv from A. Eberle Support-Team.

Adjust CSV-File as desired with Notepad or MS Excel.

Save CSV-File as lvrsys_t104_target.csv (MS-DOS File if MS Excel is used) on a FAT32

formatted USB stick.

Connect USB stick to LVRSys™.

Select menu item Communication->IEC60870-5-104->T104 CSV load.

0 LVRSys™ IEC 60870-5-104 slave can be linked in the first instance to a system IP. This is useful if redundancy systems are used to communicate or there is an additional connection via other networks such as WLAN or UMTS. LVRSys™ IEC 60870-5-104 slave reads only the first instance.

In redundant systems with different IP addresses and the same port address

T104 IP Bind must be activated.
