Hi sir...Please find a paper (experimental) for exact power balance although they have not revealed the commercial inverter's active anti-islanding method used...I think it must have been Sandia Freq/Volatge shift..However, please also find attached  a paper that may help to guess, which method has been used for which transient system signal resulting out of anti-islanding action. Sorry, however it is for solar PV inverter

Regards

Thank you Vyas. The problem with inverters is well solved but with synchronous generator or asynchronous generator is not solved for the case of Automatic reclosing process with ideal balance and short time 300 ms :(

Hi Srete,

I would request a clarification, please.

By ideal power balance, I presume you imply that the islanded network is capable of handling its own load when isolated ? (Or have I got it wrong ?)

If my interpretation is correct, then further, is the subsystem to be islanded assumed to exchange zero power from the remaining network prior to islanding ??

Please do correct me in case I have missed something.

With best wishes.

Dear Sanjay

The second assumption is closer. Power production of generator and power consumption of network are the same. Breaker at the point of  connection is open at zero power pasing through it, so there is no power mismatches to exitate and trip any fast U>, U< or f>, f
