Abstract

In the last years, hydraulic powered chassis control systems have been replaced by electrical systems due to efficiency reasons. Additionally, more and more comfort electronics have been integrated. These circumstances have lead to a high power demand in today's automotive power nets. For this reason, voltage stability has become an important design criterion of the power net. This paper describes a simulation based method to optimize the power net topology and the dimensioning of components with regard to voltage stability requirements. A Modified Discrete Particle Swarm Optimization is used in combination with a physical power net simulation. In order to optimize the topology itself, a tool flow for an automated change of the simulation model is presented. To achieve best possible performance, the influence of the configuration parameters on the algorithm performance is evaluated and appropriate parameters are chosen for the given problem. Finally, exemplary optimization results are shown by pointing out optimal topologies for different constraints of the minimum terminal voltage.

基于改进离散粒子群的14v汽车电网拓扑优化设计

在过去的几年里，由于效率的原因，液压动力底盘控制系统已经被电气系统所取代。此外，越来越多的舒适电子设备已经集成。这些情况导致了当今汽车电网的高功率需求。因此，电压稳定性已成为电网设计的一项重要标准。本文介绍了一种基于仿真的电网拓扑结构优化和元器件尺寸优化的方法，以满足电压稳定的要求。结合物理电网仿真，提出了一种改进的离散粒子群优化方法。为了优化拓扑本身，提出了一种自动更改仿真模型的工具流程。为了获得最佳性能，评估了配置参数对算法性能的影响，并针对给定问题选择了合适的参数。最后，通过指出不同最小端电压约束下的最优拓扑，给出了示例性优化结果。
