runpf does not enforce any line limits. You need to run optimal power flow 
(runopf).

Subject: Line loading limit

Hello everyone,
I want to ask a simple concept of line loading limit, As i have asked earlier 
also the rate A variable is only used in MATPOWER to limit the line. Other two 
rates are of no use.
I am trying to make a line congested by limiting its limit.
here is my following case-
define_constants;
mpc=loadcase(case30)
mpc.branch(:,RATE_A)=10;
results=runpf(mpc);

I firstly i run the above code without limiting the rate and then after 
limiting the rate, but the power loss is  not changing at all in any of the 
cases..
help me out.
thanks in advance.:)
