By using disturbance recorder (DR) you can analyse accidents in network. In this article I’ll show how to configure “DR collector tool” and how to use it. More about this tool you can read in manufacturer‘s ABB manual “LIB, CAP and SMS Tools for Relays and Terminals 1MRS752008-MUM”.

“DR collector tool” is used to analyse tripping of protections, signals of control, signals of blocking. By using this tool you can analyse sequence of events.

 

There are several steps after which you can use “DR collector tool”:

a) There should be configured signals of control, signalization and interlocking;
b) Also should be configured protections;
c) By using „Relay configuration tool“ should be inserted function block „MEDREC16“ in program unit „Registr“;
d) Various already configured signals should be connected to function block „MEDREC16“
e) By using „Relay setting tool“ application by using bits masks there should be set which signals will start disturbance recorder.

All these steps will be shown in this article.
How to configure protections see these articles:
No.15 „CAP505 – NOC3High protection: configuration and testing“
No.16 „CAP505 – protection NOC3Inst with UV3Low blocking: configuration and testing“
No.17 „CAP505 – CBFP protection: configuration and testing“

 

How to configure configuration of control and indications check these articles:

No.12 „CAP505 : Configuration of circuit breaker, truck, earth switch positions“
No.18 “CAP505: Configuration of control and testing tripping time of protections”

 

More about function block „MEDREC16“ you can read in manufacturer‘s ABB manual MEDREC16 Transient Disturbance Recorder 1MRS752341-MUM.

Now we‘re going to begin configuration of disturbance recorder.

1. Select project‘s object (in my case it is „IC-1“) and run „Relay Configuration Tool“ application:

20-1

Type password „ABB“:

20-2

 

2. In project configuration tree select program unit “Registr”. Open it:

20-3

 

3. Insert function block „MEDREC16“:

20-4

20-5

 

Function block „MEDREC16“:

20-6

 

4. Insert variables IL1, IL2, IL3 and connect them to function block „MEDREC16“ as shown in picture:

20-7

20-8

 

 

5. Insert variables U12, U23, U31 and connect them to function block „MEDREC16“ as shown in picture:

20-9

20-10

 

 

6. Insert variables BIO1_5_BI1, BIO1_5_BI2, BIO1_5_BI5, BIO1_5_BI6, BIO1_5_BI7, BIO1_5_BI8 and connect them to function block „MEDREC16“ as shown in picture:

20-11

Comment purpose of variables:

20-12

 

7. Insert variables PS1_4_HSPO1, PS1_4_HSPO2, PS1_4_HSPO3 and connect them to function block „MEDREC16“ as shown in picture:

20-13

Variable PS1_4_HSPO1 is close command (binary output), variable PS1_4_HSPO2 is open command (by using control switch or by tripping some protection – NOCHighTrip, NOCInstTrip). The variable PS1_4_HSPO3 is CBFP command.

8. Insert variables NOCHighTrip, NOCInstTrip and NOCCBFP connect them to function block „MEDREC16“ as shown in picture:

20-14

Here NOCHighTrip, NOCInstTrip and NOCCBFP are variables of protections tripping. By tripping of one of them there will be start disturbance recorder.

Configuration of disturbance recorder is complete.

9. Save configuration by selecting „File>Save“. Compile configuration by selecting command „MAKE>MAKE“:

20-15

10. Close „Relay Configuration tool“ application by selecting „File>Exit“.
The next step is to set parameters of disturbance recorder.
11. Select project‘s object (in my case it is „IC-1“) and run „Relay Setting Tool“ application:

20-16

12. By selecting „Measurement>Medrec16>Control Setting“ set parameters as shown in picture:

20-17

13. By selecting „Measurement>Medrec16>Trg Setting“ set parameters as shown in picture:

20-18

In this window you can set binary inputs which by activating will start disturbance recorder. Why „BI enable“ and „BI mode“ are set to 4095?

In manual of function block „MEDREC16“ you can find bit masks table:

20-19

I‘ve configured disturbance recorder in such way, that activated binary inputs BI1÷BI12 will start disturbance recorder:

20-20

From this table you can understand that each input of function block „MEDREC16“ has it‘s own value, for example BI1=1, BI8=128. I need sum of binaries inputs BI1÷BI12 bit masks. An this sum I need to write in „BI enable“ window. Sum of BI1÷BI12 bit masks: 1+2+4+8+16+32+64+128+512+1024+2048=4095.

The same number (4095) I write to „BI mode“ window. In „BI enable“ parameter you set which binaries inputs to activate , in „BI mode“ parameter you define which activated binary input will start disturbance recorder by falling or rising signal front. If binary input is set to „1“ then starting of disturbance recorder is activated by rising signal front.

14. Now I‘m going to set which analogues channels will fix disturbance recorder.
We need to set IL1, IL2, IL3, U12, U23, U31 analogues channels. After exceeding IL1, IL2, IL3 the disturbance recorder will start.

In manual of function block „MEDREC16“ “ you can find bit masks table:

20-21

The sum of IL1, IL2, IL3 is 1+2+4=7. This number write to parameter „Over lim. enable“.

Disturbance recorder will also start after undervoltages U12, U23, U31 are active.

 

In manual of function block „MEDREC16“ “ you can find bit masks table:

20-22

U12=512, U23=1024, U31=2048, the sum is 3584. Write this number to parameter „Under lim. enable“.

20-23

Write this number to parameter „AI channels used“:

20-24

In parameter „AI channels used“ you enable which analogues channels will trigger disturbance recorder.

15. Now we need to define settings of current and voltage. At this setting will be start disturbance recorder. I set parameter „Over limit ILx“ to „1“. This means that setting for IL1 either IL2 or IL3 > 1xIn.

After exceeding IL1, IL2, IL3>1xIn the disturbance recorder will start. In window „Over limit ILx“ I write value „1“:

20-25

Also define settings of voltage in analogues manner: U12, U23, U31 <1xUn.
Write value „1“ to parameter „Under limit Uxy“.

20-26

 

Other settings leave as defaults.

16. Now we need to indicate every binary input (BI1÷BI12). Select „Measurement>Medrec16>BI texts“ and indicate binary inputs as shown in picture:

20-27a

20-27b

Setting of function block „Medrec16“ is complete.

Now we need to send configuration and settings to PLC REF543. In article no. 10 „CAP505 Measurements: downloading (sending) configuration and settings to PLC REF543“ you can find sending procedure.

Now we need to test „DR-Collector tool“. First step is to force tripping of protection. By using „DR-Collector tool“ application we can alalyse this tripping case

The circuit breaker should be closed:

20-28

17. I‘ll trigger protection NOC3High (see article no. 15 „CAP505 – NOC3High protection: configuration and testing“).

Setting of protection NOC3High: I=1xIn=1x5A=5A.

Principle testing scheme:

20-29

20-30

 

Inject currents and voltages from testing equipment:

Ia=5,1A, IB=5,1, Ic=5,1A. φa=0˚, φb=240˚, φc=120˚.
U12=0, U23=0V, U31=0V; φa=0˚, φb=240˚, φc=120˚.

 

 

On HMI you can see tripping of protections NOC3High and CBFP:

20-31

 

In „Events windows is fixed that disturbance recorder „MEDREC16“ started:

20-32

 

 

By using „DR-Collector tool“ I‘m going to read tripping of protection NOC3High.

18. Run „DR-Collector tool“ application by selecting „System Tools> DR-Collector tool“:

20-33

 

 

19. In „DR-Collector tool“ window select „Tools>Recorder Tool…“:

20-34

 

 

20. In „Recorder Tool“ window select „Transfers>Upload Recording…“:

20-35

20-36

 

 

21. In „Upload Recording“ window select „Upload All“:

20-37

 

22. Press „OK“:

20-38

 

23. In „DR-Collector Toll“ window select 3-rd record. Open it by double click on left mouse button:

20-39

 

24. „Draw Tool“ application:

20-40

In this window you can analyse magnitudes of currents, tripping of protections and binary inputs, time of tripping of protections and binary inputs.

 

Zoomed picture:

20-41

 

By selecting „View>Goto trigger point“

20-42

automatically will be shown trigger point of protection NOC3High:

20-43

From picture you can also see that binary inputs BI10 (variable NOCHighTrip)  activated. By using marks M1 and M2 you can analyse various timing between separate events.
Conclusion: configured „DR-Collector tool“ works correct.
