为了验证混联式混合动力系统(HPS)的可行性及其工作特性,对于两种混联式混合动力系统的拓扑结构和工作模式进行对比分析;一种是典型双模式混联混合动力系统,另一种是新型基于对转双转子电机的混合动力系统。使用了一种先前开发的HPS数学模型,对两种系统小负载行驶工况和大功率加速工况下的工作特性进行了仿真。结果表明:这两种系统都可以有效地避免功率循环现象,提高传动效率;且相对于传统单模式混联混合动力系统,新型HPS系统在控制电机性能要求上更具优势:尽管该HPS的控制比较复杂,但是,减小了汽车的尺寸、质量,甚至于降低了价格。
In order to verify the feasibility of HPS and its operating characteristics, the topologies and operating modes of two hybrid HVDC hybrid systems are compared and analyzed. One is a typical two-mode hybrid hybrid system, The other is a new hybrid system based on a dual rotor motor. A previously developed HPS mathematical model was used to simulate the operating characteristics of the two systems under light-load driving conditions and high-power acceleration conditions. The results show that both of these systems can effectively avoid the power cycle and improve the transmission efficiency. Compared with the traditional single-mode hybrid system, the new HPS system has more advantages in controlling the performance of the motor. Although the HPS control Complicated, however, reduces the size, quality and even the price of the car.
