摘要

本文研究了特高压-直流换向阀的电磁场特性。建立了三维电场仿真模型，采用了考虑水路对整体电场分布影响的间接耦合方法。并对不同工况下特高压-直流换向阀关键位置的电场分布进行了计算和评价，结果表明水路对阀塔整体电绝缘有一定的影响。此外，根据载流电路的布置和不同设备的材料磁导率，建立了阀塔的三维简化磁仿真模型。研究发现，功率模块外壳的材料特性对特高压-甚高频换流阀的整体磁场分布有很大影响。

Research on the Electromagnetic Characteristics of UHV-VSC Converter Valve

The characteristics of electromagnetic field for UHV-VSC converter valve are studied in this paper. The 3D electric field simulation model is established, and the indirect coupling method which takes the influence of water circuit on the overall electric field distribution into account is adopted. And the electric field distribution of the key positions of the UHV-VSC converter valve under different working conditions is calculated and evaluated, the results indicate the water circuit has some influence on the overall electrical insulation of valve tower. Besides, according to the arrangement of current carrying circuit and the material permeability of different equipment, a 3D simplified magnetic simulation model of valve tower is also set up. It was found that the material characteristic of power module shell has great influence on the overall magnetic field distribution of UHV-VSC converter valve.
