摘　　要：1 000 MW水轮发电机对效率提出了很高的要求,因此需要对各个部分的损耗进行严格的控制。对于定子端部损耗,主要是通过对定子端部结构的材料和局部结构进行优化来实现。本文针对定子齿压板选取不同的材料,以及压指和压板采用不同的局部结构优化方案,对定子端部的磁场和损耗进行了三维仿真对比计算,并根据计算结果对施工设计给出了具体的建议。Efficiency is becoming increasingly important to1000MW hydro generator.Loss of efficiency in different components should be minimized to certain level.In order to reduce the losses in the end part of stator,high efficiency materials and breaking-through structural design are employed.In this paper,comparison of different materials,different structural design methods for stator pressure finger and press plate is made.3D finite element model is set up for stimulation calculation,along with authors'specific suggestions for generator design based on calculations.
