摘　　要：通过对感应电动机群分组聚合方法的研究,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。首先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,结合发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。进一步考虑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,以保证聚合结果具有较高精度,并与另外几种分组聚合情况进行了比较。最后针对一个典型厂用电系统,利用PSCAD/EMTDC程序对所给方法进行了仿真验证,证明了其有效性。The grouping polymerization methods of the induction motor group are studied, and a method of it for process research of plant power switch is given. Firstly, by referencing the polymerization method of the induction motor used in transient stability simulation calculation of power system and combining with the characteristics in the process of plant power switching, a induction motor group polymerization method was presented based on capacity reduction. Furthermore, in order to reduce the error of this method resulted by polymerization, a suitable grouping way was presented to ensure that the characteristics of the induction motor group divided into a group are similar and this polymerization result has a higher accuracy. This polymerization was compared with other several grouping polymerizations. Finally, aiming at a typical plant power system, the simulation of given method was carried out by PSCAD/EMTDC program and its effectiveness was verified.
