Analytical Calculation of No-load Air-gap Magnetic Field of Non-salient Pole Synchronous Generator by Applying the Distributed Magnetic Circuit Approach
摘要
Abstract
In this paper, the distributed magnetic circuit approach was applied to calculate the air-gap magnetic field distribution of non-salient pole synchronous generator. The influence of the magnetic circuit saturation can be considered effectively by the distributed magnetic circuit approach. Furthermore, the relative permeance function of air-gap was calculated by conformal transformation method, which considered the effect of stator and rotor slotting. The calculated air-gap magnetic flux density was compared with that obtained from finite-element method simulation. The calculation result considering the effect of slotting is more accurate. Especially, air-gap magnetic flux density waveform at the centerline of the air-gap is the most accurate and effective. The good agreement between calculated and simulation results verifies the accuracy of the distributed magnetic circuit approach with considering the effect of slotting, which provides a reliable guarantee for the generator design and performance analysis.关键词
