Dynamic behavior of induction machines in ATP-EMTP with space harmonics
This work develops a space-vector model of a squirrel-cage induction machine that incorporates the effects of spatial harmonics arising from the winding distribution. The modeling approach includes the first, fifth, and seventh spatial harmonics, which are the components with the greatest influence on the machine’s magnetic field.

安装线路避雷器是输电线路最有效的防雷方法之一,常规的避雷器安装方式未考虑实际杆塔的结构、地形以及闪络成本等问题,导致技术经济性较差,存在一定的盲目性。为研究避雷器的经济性安装方案,基于ATP-EMTP与电气几何模型建立了同塔双回杆塔电磁暂态分析模型。研究了杆塔结构、地形地貌对双回线路闪络风险的影响,并考虑线路闪络成本对避雷器安装方式的影响,提出利用技术经济性指标W对避雷器不同安装方式下的防雷效果和经济性进行综合评估,当W>0时,避雷器安装具有经济性,W值越大,技术经济性越强。
