Siemens Tackles Increasing Power Demands with the Help of Simulation

能源

L. Jovelli
Siemens, Brazil

从发电到将电分配到最终用户,整个输电网路中都会使用电力变压器和并联电抗器来进行电压转换及无功功率吸收。在位于 Jundiai, São Paulo 的西门子巴西分公司,设计师们使用多物理场仿真来验证网路集成变压器和并联电抗器能在不产生过热的情况下处理不断增长的电力需求,确保他们可以安全地进行操作。他们已经在变压器和并联电抗器设计中使用了仿真,这样可以有效减少热点,同时仿真还可以优化变压器油的流通从而进行更好的冷却。他们的工作包括创建一个油浸式电力变压器的多物理场模型以研究热工水力性能。这是西门子或其他任何地方的首个 3D 变压器模型。随着仿真准确性一步步得到验证,这些仿真结果不仅可以防止设计的失败,而且也可以用于优化材料和所需制冷配件的数量,有助于降低开发成本。
