| 摘 要： | 直流换流站阀塔的三维电场计算对阀塔屏蔽罩设计与表面场强控制具有重要的指导作用;但由于阀塔屏蔽罩体积庞大、结构复杂,其几何建模与数值仿真都存在相当的难度。为节省计算资源,首先应用ANSYS参数化设计语言(APDL)建立阀塔的整体剖分模型,然后采用伽辽金曲面间接边界元法对屏蔽罩表面场强进行分析,计算阀塔屏蔽罩表面的三维电场分布。计算结果表明:在当前设计方案下,屏蔽罩表面最大场强为20.2 kV/cm,以30 kV/cm作为起晕场强判据,屏蔽罩无起晕现象。该数据为换流站阀塔屏蔽罩的设计规划提供了参考依据。

| Abstract: | The calculation results of three-dimensional electric field of valve tower in DC converter station plays important directive role in the design of shielding case for valve towers and the control of its surface field intensity.However,due to its enormous volume and complex structure,there are difficulties in the geometrical modeling and digital simulation of shielding case for valve tower.To save computing resource,firstly utilizing ANSYS parametric design language(APDL) an integral dissection model is built... |
