modelThirdOrder_AVRI
31-bus system with 3rd-order machine and AVR Type I
Extends from Modelica.Icons.Example (Icon for runnable examples), OpenIPSL.Examples.PSATSystems.TwoArea.BaseClasses.BaseOrder3 (Template for base network and a 3rd order generator).
Information
This system is tests the third order machine with a type 1 AVR, from PSAT. Simulate the system for 20 seconds.
Variables of interest are related to the (non-)coherency observed between the synchronous machines:
order3.worder3_1.w
Note that the oscillations, which are not well damped, have opposing phases, meaning that one machine is swinging against the other, in a clear example of non-coherent machines. In addition, plot:
B6.vB30.v
Compare these results with the ones from the other example systems within the TwoArea subpackage.
