simpowersystem
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..
I am attaching the model file....
it is a matlab version 7 file
