一种基于容量归算的感应电动机群聚合方法研究

对感应电动机群分组聚合方法进行研究,给出一种用于厂用电切换过程研究的感应电动机群分组聚合方法。借鉴电力系统暂态稳定仿真计算中的感应电动机聚合方法,结合电厂厂用电切换过程的特点,给出一种基于容量归算的感应电动机群聚合方法。为减小该方法中聚合所产生的误差,给出一种适用的分组方法,保证分入一组内的感应电动机群特性相似,以保证聚合结果有较高精度。对一个典型厂用电系统,利用PSCAD/EMTDC程序对该方法进行仿真验证,证明其有效性。

Study on an Induction Motor Group Polymerization Method Based on Capacity Reduction

In this paper,the induction motor group polymerization method was studied,and then,used in the process study of switching over station power as a practical example.Referrenced with the induction motor group polymerization method in power system transient stability simulation calclation and combined with the performances of switching over station power in power plant,an induction motor group polymerization method based on capacity reduction was presented.In order to reduct the error resulted by polymerizatio...
