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%/2.5%

Transformer 4.5%/7.5%

-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.

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

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 4.5% TR 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 1.5% TR converts the primary voltage in a positive direction and adds 3.45 V (1.5% of 230 V) to the output voltage.

Figure 10-9 Response time in connection with phase spacing of2.5%

Example: For time delay 1 and voltage deviation 3%:

Phase spacing 1.5% equals to a response time of 9 s.

Phase spacing 2.5% equals to a response time of 15 s.





10.9.4 Grid impedance

The Grid impedance function can only be used if the Current measurement option is integrated (Sec. 2.2 Options).

The default is grid impedance is 0 Ω, hence the impedance is deactivated.

When the impedance is deactivated:

Current-dependent regulation is deactivated.

When the impedance is activated:

Current values are included in regulation.

Resistance symbol displays in the status window.

Set impedance in 0.01 Ω steps.

10.13.2.6 Redundancy System

0 LVRSys IEC 60870-5-104 slave can use five IEC 60870-5-104 connections simultaneously.

0 Each instance has ist own IEC 60870-5-104 process images and messages.


We take care of it.

LVRSys IEC 60870-5-104 slave does not hold any events or messages in the queue. When the connection is available again messages will be transmitted and the process informations renewed.

If there is no connection the LVRSys IEC 60870-5-104 slave will not renew process

information and collect any messages. Once the connection is available again,

the LVRSys IEC 60870-5-104 slave renews process information and transmits new

messages.

The redundant instances are always connected to the set IP addresses! If no IP

address is set, the instances connect to all networks (IP = 0.0.0.0).

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

T104 IP Bind must be enabled. Otherwise the first instance will connect with all

the networks and the other instances cannot connect.

11.8 Lightning protection

The lightning and surge protection is in all systems coordinated according to EN 61643-11 type 1 + type. 2

Figure 11-7 LIghtning protection Type 1 DV M TNC 255 FM (951305)

In case of persistent lightning strikes, the use of lightning protection module turns red. The LVRSys goes to automatic bypass mode and disconnects the electronics from the grid. To remedy the error follow the steps:

Take LVRSys out of operation (See sec. 9.2).

Replace Lightning exchange (DV MOD Art. 255 951 001).

Put LVRSys only after instruction in operation (See sec.9.1).





11.9 Transformer protection

Figure 11-8 Transformer protectionDG S 275 FM (952090)

If errors occurs like control error or thyristor error the LVRys goes automatically into the bypass mode. Following steps should be taken:

Take LVRSys out of operation (See sec. 9.2).

Contact A. Eberle Support Team.

Put LVRSys only after instruction in operation (See sec.9.1).
