4.2 Function description of the voltage regulation

The TAPCON® serves to keep constant the output voltage of a transformer with an on-load tap-changer.

The TAPCON® compares the transformer's measured voltage (U actual

) with a defined reference voltage (U desired

). The difference between U actual

and U desired is the control deviation (dU).

The TAPCON® parameters can be optimally adjusted to the line voltage response to achieve a balanced control response with a small number of tapchange operations.

The following diagram shows an overview of voltage regulation.

5 Packaging, transport and storage


5.1 Packaging

5.1.1 Purpose

The packaging is designed to protect the packaged goods during transport, loading and unloading as well as periods of storage in such a way that no

(detrimental) changes occur. The packaging must protect the goods against permitted transport stresses such as vibration, knocks and moisture (rain, snow, condensation).

The packaging also prevents the packaged goods from moving impermissibly within the packaging. The packaged goods must be prepared for shipment before actually being packed so that the goods can be transported safely, economically and in accordance with regulations.

5.1.2 Suitability, structure and production

The goods are packaged in a sturdy cardboard box. This ensures that the shipment is secure when in the intended transportation position and that none of its parts touch the loading surface of the means of transport or touch the ground after unloading.

The box is designed for a maximum load of 10 kg.

Inlays inside the box stabilize the goods, preventing impermissible changes of position, and protect them from vibration.

5.1.3 Markings

The packaging bears a signature with instructions for safe transport and correct storage. The following symbols apply to the shipment of non-hazardous goods. Adherence to these symbols is mandatory.


Protect against moisture

Center of mass

5.2 Transportation, receipt and handling of shipments

In addition to oscillation stress, jolts must also be expected during transportation. In order to prevent possible damage, avoid dropping, tipping, knocking over and colliding with the product.



If a crate tips over, falls from a certain height (e.g. when slings tear) or is subject to an unbroken fall, damage must be expected regardless of the weight.

Every delivered shipment must be checked for the following by the recipient before acceptance (acknowledgment of receipt):

▪ Completeness based on the delivery slip

▪ External damage of any type

The checks must take place after unloading when the crate or transport container can be accessed from all sides.

Visible damage If external transport damage is detected on receipt of the shipment, proceed as follows:

▪ Immediately record the transport damage found in the shipping documents and have this countersigned by the carrier.

▪ In the event of severe damage, total loss or high damage costs, immediately notify the sales department at Maschinenfabrik Reinhausen and the relevant insurance company.

▪ After identifying damage, do not modify the condition of the shipment further and retain the packaging material until an inspection decision has been made by the transport company or the insurance company.

▪ Record the details of the damage immediately onsite together with the carrier involved. This is essential for any claim for damages!

▪ If possible, photograph damage to packaging and packaged goods. This also applies to signs of corrosion on the packaged goods due to moisture inside the packaging (rain, snow, condensation).

▪ Be absolutely sure to also check the sealed packaging.

Hidden damage When damages are not determined until unpacking after receipt of the shipment (hidden damage), proceed as follows:

▪ Make the party responsible for the damage liable as soon as possible by telephone and in writing, and prepare a damage report.

▪ Observe the time periods applicable to such actions in the respective country. Inquire about these in good time.

With hidden damage, it is very hard to make the transportation company (or other responsible party) liable. Any insurance claims for such damages can only be successful if relevant provisions are expressly included in the insurance terms and conditions.



5.3 Storage of shipments

When selecting and setting up the storage location, ensure the following:

▪ Protect stored goods against moisture (flooding, water from melting snow and ice), dirt, pests such as rats, mice, termites and so on, and against unauthorized access.

▪ Store the crates on timber beams and planks as a protection against rising damp and for better ventilation.

▪ Ensure sufficient carrying capacity of the ground.

▪ Keep entrance paths free.

▪ Check stored goods at regular intervals. Also take appropriate action after storms, heavy rain or snow and so on.

8.2.8 Setting motor runtime monitoring

You can use this motor runtime parameter to set the motor runtime. The motor-drive unit's runtime can also be monitored by the device. This function is used to identify motor-drive unit malfunctions during the tap-change operation and to trigger any actions needed.

Behavior The motor-drive unit issues the Motor-drive unit running signal during the tap-change operation. This signal is present until the tap-change operation is complete. The device compares the duration of this signal with the set motor runtime. If the set motor runtime is exceeded, the device triggers the following actions:

1.

Motor runtime monitoring message is issued

2. Continuous signal via output relay Motor-drive unit runtime exceeded (optional)

3. Pulse signal via Trigger motor protective switch output relay (optional)

Parameterizing control input

To use runtime monitoring, you need to correctly wire the corresponding control input and parameterize to Motor running . The motor runtime must also be set.


8 Operation

Wiring control input/output relay

If you want to monitor the motor runtime, the device and motor-drive unit must be connected and parameterized as shown below.

3 Motor protective switch tripped

GPO output relay (optional)

4 Motor runtime exceeded GPO output relay (optional)

If you want to use the output relay, the feedback from the motor-drive unit

Motor protective switch triggered must be wired to a control input and parameterized. This message resets the Motor runtime exceeded output relay when the motor protective switch is switched back on and activates the Motor protective switch triggered message.

If the runtime monitoring is set to "0.0 s", this equates to it being switched off.

All of the required for the regulation function are described in this section.

For voltage regulation, you can set the following parameters:

▪ Control response T1

▪ Delay time T2

For voltage regulation, you can set delay time T1 and also delay time T2.

The following sections describe how the regulation function responds in both cases:


8 Operation

Behavior only with delay time T1

If the measured voltage U actual

is within the set bandwidth , no control commands are issued to the motor-drive unit for the tap-change operation.

Control commands will also not be issued to the motor-drive unit if the measured voltage returns to the tolerance bandwidth within the set delay time

T1 . However, if the measured voltage deviates from the set bandwidth for a long period , a tap-change command occurs after expiration of the set delay time T1. The on-load tap-changer carries out a tap-change in a raise or lower direction to return to the tolerance bandwidth.

8.4.1 Setting desired value 1...3

You can use this parameter to set up to 3 desired voltage values U

Ref

. The desired voltage value is specified as a fixed value. The desired value 1 is the default desired value. Desired values 2 and 3 are activated if there is a continuous signal at factory-preset control inputs X4:17 or X4:18 provided you have programmed these previously. If there is a signal at several control inputs at the same time, desired value 2 is activated.


8 Operation

Options for setting the desired values

The device provides the following ways of changing the desired voltage value during operation:

▪ Using the control parameters menu item via the operating screen

▪ Using binary inputs

▪ Using control system protocols if a communication card is ready for operation

Reference of kV and V for voltage transformer

Desired values set in kV refer to the primary voltage of the voltage transformer. Desired values set in V refer to the secondary voltage of the voltage transformer. The transformer data must be entered correctly for this display.

To set the desired value, proceed as follows:

1.

> Control parameter > voltage regulator > Press until the desired parameter is displayed.

2. If you have already entered the transformer data, press to select the unit you want: "V" or "kV".

3. Press .

ð The selected desired value is active.


8 Operation

8.4.3 Bandwidth

You can use this parameter to set the maximum permissible deviation in measured voltage U

Act

. The deviation relates to the activated desired value.

The following sections describe how you determine and set the bandwidth required.

8.4.3.1 Determining bandwidth

In order to set the correct value, the transformer's step voltage and nominal voltage must be known.

Too small/large a bandwidth

You have to set the bandwidth in such a way that the output voltage of the transformer (U

Act

) returns to within the specified tolerance bandwidth after the tap change. If too small a bandwidth is defined, the output voltage exceeds the bandwidth selected and the device immediately issues a tapchange command in the opposite direction. If a very large bandwidth is selected, this results in a major control deviation.

The following value is recommended for the bandwidth setting:

Figure 41: Recommended bandwidth

U n-1

U n

U nom

Step voltage of tap position n-1

Step voltage of tap position n

Nominal voltage

The following transformer values are used to determine the recommended bandwidth:

Nominal voltage U nom

= 11,000 V

Step voltage in tap position 4 U

Step4

= 11,275 V

Step voltage in tap position 5 U

Step5

= 11,000 V

The following section describes how you can set the bandwidth.

8.4.3.2 Setting the bandwidth

To enter the determined bandwidth, proceed as follows:

1.

4. Press .

ð The bandwidth is set.

8.4.3.3 Visual display

The deviation from the set bandwidth is shown visually in the device's display. The measured voltage highlighting shows whether the measured voltage is above, within or below the set bandwidth . Progress of delay time T1 is indicated by the gradual filling of the time bar . The seconds display above this indicates the remaining delay time T1.

8.4.4 Setting delay time T1

Use this parameter to set delay time T1. This function delays the issuing of a tap-change command for a defined period. This prevents unnecessary tapchange operations if the tolerance bandwidth is exited.


8 Operation

To set the delay time T1, proceed as follows:

1.




3. Press to increase the time or to reduce it.

4. Press .

ð The delay time T1 is set.

8.4.5 Setting control response T1

The control response T1 can be set to linear or integral.

Linear control response T1 With linear control response, the device responds with a constant delay time regardless of the control deviation.

Integral control response

T1

With integral control response, the device responds with a variable delay time depending on the control deviation. The greater the control deviation

(ΔU) in relation to the set bandwidth (B), the shorter the delay time. The delay time can therefore be reduced down to 1 second. This means that the device responds faster to large voltage changes in the grid. Regulation accuracy improves as a result but the frequency of tap-changes increases too.

8.4.6 Setting delay time T2

With this parameter, you can set delay time T2. Delay time T2 is used to compensate for large control deviations faster.

The delay time T2 only takes effect if more than one tap-change operation is required to return the voltage to within the set bandwidth. The first output pulse occurs after the set delay time T1. After the set tap-change delay time

T2 has elapsed, additional pulses occur in order to correct the existing control deviation.

The following requirements must be noted to set delay time T2:

▪ The delay time T2 must be greater than the switching pulse time.

▪ The delay time T2 must be greater than the maximum operating time of the motor-drive unit.

▪ The delay time T2 must be less than the value set for delay time T1.

8.6 Compensation

You can use the "Compensation" function to compensate for the load-dependent voltage drop between the transformer and consumer. The device provides 2 methods of compensation for this purpose:

▪ R&X compensation (line drop compensation)

▪ Z compensation

8.6.1 Line drop compensation

R&X compensation (LDC) requires exact cable data. Line voltage drops can

be compensated very accurately using LDC.


8 Operation

To set R&X compensation correctly, you need to calculate the ohmic and inductive voltage drop in V with reference to the secondary side of the voltage transformer. You also need to correctly set the transformer circuit used.

8.8 Configurable inputs and outputs

You can individually configure the digital inputs (GPI ) and outputs (GPO ).

The following digital inputs and outputs are available:

▪ 6 digital inputs (GPI1...6)

▪ 2 digital outputs (GPO1 and 2)

8.8.1 Linking inputs with functions

You can activate the inputs as follows :

▪ Statically using signal statuses

– The input signal must be continually present (status: high level).

▪ Dynamically using pulses

– A pulse (rising edge) is needed at the input. The input signal must change its status from "Low" to "High". If you are using a pulsed input, you can trigger the assigned function at the same time as the keys connected to the inputs also using the control system.

You can recognize pulsed inputs from the preceding "P:". The note "Warning: P = pulsed inputs" is displayed on the screen.

You can assign one of the following functions to each of the digital inputs

(GPI 1...6):

If you assign the same functionality to two inputs, the device produces an event message. This also applies if you assign the same functionality via a static input and via a pulsed input.

Other examples of double assignment of functions are (n, m = 1...6):

▪ GPI n = master/follower and GPI m = P: DV 1

▪ GPI n = master/follower and GPI m = P: DV 2

To assign a function to a digital input or to deactivate it, proceed as follows:
