Abstract

A three-dimensional model of a turbogenerator is proposed, which allows analyzing its magnetic state in various operating modes, including with reactive power consumption. For this purpose, the Easy-MAG3D software based on spatial integral equations was used, which made it possible, thanks to the use of parallel computing processes, to calculate the magnetic field in a full three-dimensional formulation. Studies of the main negative phenomena that occur in the mode of reactive power consumption and affect the state of the turbo generator, namely, saturation of the stator and rotor cores and an increase in the axial component of magnetic induction in the end zone of the stator, leading to increased losses and increased heating, as well as changes in electromagnetic forces occurring in the frontal parts of the stator winding. Conclusions are drawn about the most significant factors that worsen the working conditions of turbogenerators when consuming reactive power.

具有无功功率消耗的涡轮发电机中电磁过程和力相互作用的特点
摘要 提出了一种涡轮发电机的三维模型,可以分析其在各种运行模式(包括无功功率消耗)下的磁场状态。为此,使用了基于空间积分方程的 Easy-MAG3D 软件,由于使用了并行计算进程,该软件能够以全三维形式计算磁场。研究了在无功功率消耗模式下发生并影响汽轮发电机状态的主要负面现象,即定子和转子铁芯饱和、定子端部区域磁感应强度轴向分量增加导致损耗增加和发热增加,以及定子绕组正面部分发生的电磁力变化。得出的结论是,在消耗无功功率时,导致涡轮发电机工作条件恶化的最重要因素。
