invalid shunt status
Hello,
I am trying to increase BShunt of a fixed shunt element using shuntchng and I get error -1 i.e. invalid shunt status. Here is how I write it:
ierr = psspy.shunt_chng(bus,id,intgar1=1, realar2=100)
I am certain that this shunt element exist and I the bus number and id are correct. Could anyone please tell me what I am doing wrong?
I tried changing B-Shunt through GUI and I get the following:
Messages for api SEQFIXEDSHUNT_DATA
Messages for shunt "3T" at bus 336 [extended bus name]: (002531)
Warn: Sign discrepancy: positive sequence G=.00000 and zero sequence G=-.800000 (002532)
In "Short Circuit" tab of the element properties, G-Zero (MW) has negative sign and B-Zero (MVAr) has a positive sign. Maybe I do not understand their meaning properly. Could anyone please explain these to me?
Thank you in advance.
