Abstract

In this paper, computer simulation of electric vehicle (EV) operation is given according to two different configurations of EV drivetrain system. The first one was traditional schema with single electric motor and the second one was new configuration based on modular cascade machine (MCM), which consist of two motors. All motors were synchronous machines with permanent magnets (PMSM) with vector control in two zones of angular speed regulation and with efficiency optimization control considering of both copper and iron losses. Machine modules in MCM were chosen at equal rated power, but with different pole number. Computer simulation is represented by the approach of energetic macroscopic representation (EMR). Results of computer simulation demonstrated advantage of less power usage of MCM-based EV as compared with single motor EV on 8.8% in urban driving schedule and equivalence of two configurations in highway driving schedule.

电动汽车单级联电机和组合级联电机运行效率评价

本文针对电动汽车动力传动系统的两种不同配置，进行了电动汽车运行的计算机仿真。一种是传统的单电机结构，另一种是基于模块化串级机(MCM)的双电机结构。所有电机均为永磁同步电机，采用两区角速度矢量控制，同时考虑铜损和铁损的效率优化控制。在MCM中，选用了额定功率相等但极数不同的机器模块。计算机模拟采用能量宏观表示(EMR)方法。计算机仿真结果表明，与单电机电动汽车相比，基于mcm的电动汽车在城市行驶计划中能耗降低8.8%，在高速公路行驶计划中两种配置等效。
