Microgrid

Submitted by alexandra.bursuc on Thu, 06/11/2020 - 12:24
Hi everyone I'm trying to simulate the circuit with the microgrid without SM presented in the youtube video but I don't have the relay library so I can't finish the circuit. Can anyoane tell me if I can put something else instead of those? I'm more intrested in the islanding detection .

Flashover switch flashes over before threshold is met

Submitted by alessab on Mon, 03/16/2020 - 18:54

Hello,

I'm dealing with fast transient from lighning strikes.

One of my Flashover switches flashes over at a voltage which is much lower than its set flashover voltage.

This seems to be related to calculation step, as the smaller the step, the closer the flashover is to Vflash.

Nontheless, the flashover takes place (significantly) before the voltage reaches its Vflash value. Is this because the flashover also depends on voltage derivative?
 

Thank you so much for any help in understanding what's happening in the model.

Best regards
