4. Analysis of Synchronous machine dynamics using a novel equivalent circuit model
Sammanfattning : This thesis investigates simulation of synchronous machines using a novel Magnetic Equivalent Circuit (MEC) model. The proposed model offers sufficient detail richness for design calculations, while still keeping the simulation time acceptably short. Different modeling methods and circuit alternatives are considered. LÄS MER
