Hi support team.

I'm configuring P132-658 relay.

In which, I want to obtain the F79 unsuccessfull via 61850. At the setting I only found F79 sucessfull but not unsuccessfull.

How can i resolve thí problem?

Hello,

can you precise your problem to allow to help you? Are you looking to the informations provided over IEC61850 for the auto-reclose function (ANSI 79)?

Yes, of cource. In my project, my SCADA software ne gather datas from P132 relay via 61850 protocol. In wwhich, The F79 successull and F79 Unsuccessfull signals are required. With F79 successfull I found it at setting item. But with F79 Unsuccessful I couldnt find it at anywhere ( setting and MCL tool). How can i get this signal.
Thank much.

Hi @manhkhuong,

In fact, this signal isn't available natively:

You will need to make a logic using the signals and timers available, something like this pseudo-code:

If MAIN: Close command: ON  and ARC: Reclaim time running: ON then:

Wait until Reclaim time elapsed: If NOT Reclosure successful: ON then Reclosure failure.

As it is a Px30 you may need to split it into 2 or 3 equations and use pick-ups and drop-offs.

Then you can report the logic signal as a GGIO. You may check the signals available and do the logic as you wish. If you are using SynchroCheck 25 it will be simpler cause you could monitor the ASC: Close rejection.

I hope it helps.

Best Regards
