This course is dedicated to terminal VAMP40. Software VAMPSET version 2.2.136 (date 9.6.2014) is used to configure VAMP40 PLC. In this course we are going to use Windows XP operating system.

In this course we are going to configure standard protections for feeder.

PLC VAMP40 is used to protect feeders, motors, capacitor banks. VAMP40 full description you can find in manufacturer’s manual  “VAMP40 Feeder and motor protection relay – technical description“.

Operating voltage – 220 DC, secondary current of current transformer – 5 A.

 

VAMP40 has such protection functions:

Overcurrent protection

Broken conductor protection

Current unbalance protection (motor protection)

Phase reversal / incorrect phase sequence protection (motor protection)

Stall protection (motor protection)

Frequent start protection (motor protection)

Termal overload protection (motor protection)

Undercurrent protection (motor protection)

Earth fault protection

Intermittent transient earth fault protection

Capacitor bank unbalance protection

Capacitor overvoltage protec

Directional earth fault protection

Residual voltage protection

Single-phase overvoltage protection

Single-phase undervoltage protection

Reverse and underpower protection

Circuit-breaker failure protection

Programmable stages

Optional arc fault protection (with an external module)

 

This PLC has also disturbance recorder. By using disturbance recorder you can explore events list and disturbances in electrical grid. In events list you can understand what happened at failure of network.

In this course we are going to configure standard protections for feeder: overcurrent protections (I>, I>>), earth fault protection (I0>), circuit-breaker failure protection (CBFP).

  1. Reading VAMP40 configuration.

Unlike with Siemen and ABB PLCs, by working with VAMP40 PLC you can’t create new configuration file. All you need is to read existing configuration from PLC VAMP40. After reading this configuration you will be able to modify this configuration. How to red existing configuration from VAMP40 you can read in article “VAMP40 relay – reading existing configuration and settings”.

After reading existing configuration, you will see untitled VAMP window:

Fig.1

 

2. Setting general parameters of VAMP40.

First you need to set date and time. Press button

Fig.2

Date and time are set:

Fig.3

Change name for device:

Fig.4

Changed names will be in reds markings (“Substation 33”):

Fig.5

Red markings means that we are done some changes but not saved them yet.

To save configuration press button

Fig.6

In opened window select destination folder for saving file. I’m going to save configuration file in folder “VAMP40 course”:

Fig.7

After saving configuration file, red markings is still alive:

Fig.8

Send to VAMP40 only changed parameters in configuration file by pressing button

Fig.9

When sending is complete, red markings will be changed to black markings („Name for device“ ir „Device name“):

Fig.10

Now we need to check if sending parameters to VAMP40 is successful. Press button:

Fig.11

“Device info” window updates:

Fig.12

Parameters „Name for device“ and „Device name“ has names „Substation33“, so that means that sending of changed parameters of configuration completed successfully.

Type names for inputs as shown in the picture:

Fig.13

Send configuration changes to terminal VAMP40 by pressing button:

Fig.14

VAMP40 has two binary inputs: DI1 and DI2. we are going to use these binary inputs for indicating positions of circuit breaker. Type name “Opened CB” for binary input DI1 and for binary input DI2 type name „Closed CB“ as shown in the picture:

Fig.15

Send configuration changes to terminal VAMP40 by pressing button:

Fig.16

Setting of VAMP40 general settings is completed.

 

  1. Connection scheme of VAMP40.

Terminal VAMP40 has three currents inputs IL1, IL2, IL3, two zero sequence inputs I01, I02, one voltage input U0/U12/UL1, five binary outputs T1, T2, T3, T4, A1, two binary inputs DI1, DI2 and one internal failure output IF.

More detail about technical parameters of VAMP40 you can explore in manufacturer’s manual “VAMP40 Feeder and motor protection relay – technical description.

Connection scheme of VAMP40 is shown in the pictures bellow:

Fig.17

Fig.18

Supply voltage of binary inputs varies 18…265 V DC. I‘m going to use 220 V DC voltage.

Binary output T1 will disconnect circuit breaker, binary output T2 is not used yet. Binary outputs T4 and A1 will be used for signalisation circuits: for alarm circuit and for signalisation circuit. Overcurrent protections I> and I>> activate alarm circuit (these protection disconnect circuit breaker). Earth fault protection activate signalisation circuit (this protection do not disconnect circuit breaker). Various failures of cubicle will also activate signalisation circuit. Circuit breaker failure protection (CBFP) activate binary output T3 in case if circuit breaker will not disconnected from overcurrent protection.

Why we are going to use binary output T1 to open circuit breaker? Why not binary output A1? At voltage 220 V DC current breaker capacity of binary output A1 is only 0,2 A. Current breaker capacity of binary outputs T1, T2, T3, T4 at 220 V DC is 1 A. That is 5 time more! Therefore we can use binary outputs T1, T2, T3, T4 for opening circuit breaker (if it is vacuum circuit breaker). If we have oil filled circuit breaker (old type circuit breaker), we can‘t directly use binary outputs T1, T2, T3, T4 for opening circuit breaker. In this case we must use auxxillary relays with high rate current breaking capacity.

 

  1. Setting measuring inputs.

After selecting „SCALING“ option on right window, set parameters on left window as shown in the picture:

Fig.19

Here:

CT primary – current transformer‘s primary winding (rating of current)

CT secondary – current transformer‘s secondary winding (rating of current)

VT primary – voltage transformer‘s primary winding (rating of voltage)

VT secondary – voltage transformer‘s secondary winding (rating of voltage)

Io primary – zero sequence transformer‘s primary winding (rating of current)

Io secondary – zero sequence current transformer‘s secondary winding (rating of current)

Io2 primary – zero sequence current transformer‘s primary winding (rating of current)

Io2 secondary – zero sequence current transformer‘s secondary winding (rating of current)

VTo secondary – zero sequence voltage transformer‘s secondary winding (rating of voltage)

 

What difference between analogue inputs Io1 and Io2? Analogue input Io1 can measure currents either 0 – 50 A or 0 – 10 A. Analogue input Io2 can measure currents either 0 – 10 A or 0 – 2 A (see manufacturer’s manual “VAMP40 Feeder and motor protection relay – technical description“). Analogue inputs Io1, Io2 are mainly used to configure earth fault protection. Also by using analogue inputs Io1, Io2 you can configure capacitor bank‘s current unbalance protection.

In this course we are going to use only analogue input Io1 for configuring non-directional earth fault protection.

Setting of analogue measuring inputs is completed.

 

5. Description VAMP40 LEDs.

On front side of terminal VAMP40 we can see 10 LEDs:

Fig.20

Here:

„Power“– active (lights green) when VAMP40 is powered, not free programmable

„Error“ – active when VAMP40 faulty, not free programmable

„Alarm“ – free programmable LED

„Trip“ – free programmable LED

„A“ – free programmable LED

„B“ – free programmable LED

„C“ – free programmable LED

„D“ – free programmable LED

„E“ – free programmable LED

„F“ – free programmable LED

 

How to configure free programmable LEDs we are going to learn in the next article.

For now general settings of terminal VAMP40 are set. Analogue measuring inputs are also set. In the next article we are going to configure overcurrent protection.
