IEC61850 OPC SERVER TO ABB REF615 RELAYS, ANALOG VALUES NOT UPDATING ON 800XA GRAPHICS

Hi All,

I am communicating REF615 relays to 800xA 5.1 using IEC61850 CET opc server. But in 800xA the analog values like current, voltage etc are either updating too slow or not updating at all untill a particular graphics page is refreshed.

Is this normal behaviour of IEC61850 or something went wrong in the communication.

Kindly enlighten..

Thanks

Hi,

1) IF the data is updated everytime after only refresh then following could be the reasons :

a) SIgnal might not be present in the dataset of RCB

b) By default the clients for RCB in REF615 relays in CLient 1 to Client 5. SO u must use same in 800xA side. IF you use different then the same client has to be updated in the Relay as well

2) If the signal updates sometime and doesnt updated sometimes then there is some deadband setting in relay which will sned data only if the values cross beyond a deadband. Check this as wel

3) In the metering block in relay setting must changed to nominal values.

Regards,

Did you define the RCB clients in OPC. If IED does not find any client to report to then it will send data only when asked, i.e. polling i.e. refreshing the graphic manually.
