The more important question is what you hope to see when you plot 30,000 time series? Most likely you will see nothing but a solid block of color. The following SAS code creates 5,000 time series (a fraction of what you are asking for). In this case, all series follow the same trend line, so you can make out the general trend, but in real data you are likely to see only a jumbled mess.

data Test;
call streaminit(1);
do Group = 1 to 5000;
do x = 1 to 5;
y = x + rand("Normal");
output;
end;
end;
run;

ods graphics / GROUPMAX=30000;
proc sgplot data=Test noautolegend;
series x=x y=y / group=Group transparency=0.95 lineattrs=GraphData1;
run;
