Dynamic Stability Enhancement using Genetic Algorithm Power System Stabilizer

摘要

In this paper the dynamics of a single machineconnected to infinite bus power system is analyzed. Such analysisrequires a certain level of system modeling. The main systemcomponents models are the synchronous machine, excitationsystem and the Power System Stabilizer. The Matlab/Simulink isused as a programming tool to analyze the system performance. According to the system performance a proper design for thePower System Stabilizer (PSS) using Genetic Algorithm (GA) iscarried out. Then the designed PSS is implemented in the modeland the dynamic system response is analyzed. Since thesimulation results without PSS showed unacceptable systemresponse, the system response with the PSS has improved and thePSS succeeded to stabilize an unstable system. The designed PSShas been implemented in a microcontroller. Finally, the systemresponse with PSS-microcontroller has been tested and comparedwith the simulation results.
