摘要:

永磁同步电机作为压缩空气储能系统核心部件,长期工作在密闭环境、宽转速且高频次启停的运行工况下,导致电机温升较高、噪音较大。过大的电机转矩波动也造成其模式切换过程不稳定,整体性能下降。针对上述问题,提出一种融合非支配排序遗传算法Ⅱ(NSGA-Ⅱ)与响应面法的协同优化策略,将永磁电机的齿槽转矩、损耗和转矩波动作为优化目标进行多目标优化设计。基于电磁仿真平台,构建高精度电机二维瞬态电磁场模型,引入磁热耦合计算方法对电机进行温度场仿真分析,将有限元方法计算出的电机电磁损耗作为热源,研究不同工况下的温升情况,校核电机温升特性,然后面对各参数变量互相影响的问题,利用NSGA-Ⅱ算法寻求帕累托前沿解以解决多目标优化中的矛盾,采取寻求最优组合而不是最佳值的寻优方式进行优化算法设计。结果显示,优化后的电机齿槽转矩、转矩波动及损耗都得到了显著降低,同时电机各主要结构的温升也有所下降。

Abstract:

A permanent magnet synchronous motor (PMSM), as a core component of a compressed air energy storage system, operates for extended periods under conditions characterized by enclosed environments, wide speed ranges, and frequent start-stop cycles, resulting in high temperature rise and significant noise. Furthermore, its excessive torque ripple causes instability during the motor mode switching process, thereby leading to a decline in overall performance. To address these issues, an innovative coordinated optimization strategy integrating the non-dominated sorting genetic algorithm Ⅱ (NSGA-Ⅱ) and response surface methodology (RSM) was proposed. This approach took the cogging torque, losses, and torque ripple of the PMSM as the optimization objectives for multi-objective design. A high-precision two-dimensional transient electromagnetic field model of the motor was constructed based on the electromagnetic simulation platform. The magnetic-thermal coupling calculation method was introduced to simulate the motor's temperature field, using electromagnetic losses calculated by the finite element method as the heat source. The temperature rise under different operating conditions was investigated, and the temperature rise characteristics of the motor were verified. To address the interactions among various parameter variables, the NSGA-Ⅱ algorithm was used to seek Pareto front solutions to resolve conflicts in multi-objective optimization. The optimization algorithm was designed to identify the optimal combination rather than individual optimal values. The results showed that the cogging torque, torque ripple, and losses of the optimized motor were significantly reduced, and the temperature rise of the motor's key structural components was also decreased.
