View Full Version : power system stabilizer design in matlab using simpowersyste

I am trying to design a power system stabilzer.For the same I am
observing the small signal stability of a single generator infinitr
bus sytem.I am using SimPowerSystem for the design of the system.I am
not able to design the desired system with the available blocks.what
i am doing is i am using the 3 phase pu generator model in closed
loop with the water turbine and governor system,excitation system and
generic blocks available.Also the stator terminals are connected to
the thr xmission line through a step up xmer. at the end of the
xmission line is a step down xmer..similar to the step up xmer...the
secondary windings of the reciving end (xmer) are connected to a 3
phase voltage source to represent the infinte bus..(the refernce
voltage 1 angle 0 degree per unit.
This system is showing loading effect with change in the length of
the xmission line...a small length...angular speed(w) keeps on
increasing...a large length..w keeps on decreasing and so forth..

This is a little off topic for the forum, but there might be someone with similsr project.

Just send me the file, I'll upload for you.
