Are you saying you have 30 felony's on your record already, or are you trying to say you have been charged in a 30 count indictment?
A 30 count indictment can be pleaded to 3 or so indictments if the prosecutor will allow a plea bargain.
If you have no priors and the prosecutor offers/accepts a deal then it is possible that you will walk home with probation if they are none violent charges.
On the other hand, if you have felony's on your record already (and especially 30) you will do time.
