Modeling of Single-Pulse Operated Switched Reluctance Generator and Its Verification

摘要

This paper proposes a mathematical model for a switched reluctance (SR)generator feeding a dc link through a power electronic converter. SR machines are operated in single-pulse mode at close to and above base speed. The SR generator is modeled as a current source, controllable with dc-link voltage $V_{dmathrm{c}}$ and switching angles $(lpha_{on}$ and $lpha_{omathrm{f}mathrm{f}})$ of the converter. This current source model is used to predict the dc-link dynamics for constant resistance, constant current and constant power loads. This is further utilized to derive the voltage build-up condition for an SR generator. The generator model, dc-link dynamics and voltage build-up conditions are validated through simulations and experiments.
