Question related to Slack bus ( help please ) !!

Can we set the MVAR limits of a Slack bus as Zero ( for both MAx. and Min. limits ) during operating load flow program !?

and what does the minus sign exactly mean when it's written in the limit , such this one :
Qmin. (MVAR) = -42.7
Qmax. (MVAR ) = 97

if the slack generates -373....did the limit is already exceeded !?
PS : excitation is 105%

thanks for your attention.

You can, but you probably will not converge on a solution.

and what does the minus sign exactly mean when it's written in the limit , such this one :
Qmin. (MVAR) = -42.7
Qmax. (MVAR ) = 97

Sign denotes leading vs. lagging.

if the slack generates -373....did the limit is already exceeded !?

Which program are you using? Can you post your power flow diagram?
(Is this homework?)
