摘要(Abstract)：

以舟山柔性直流输电工程中±200 k V直流电缆为研究对象,利用有限元软件ANSYS建立电缆温度场模型,并将理论建模与现场实测数据进行比对,验证了建模的正确性。在温度场建模的基础上对电缆载流量进行分析,指出在满负荷情况下,电缆载流量仍有提升空间,可以为用电高峰或者维修时的电力调度提供风险评估参考。
In this paper, ±200 k V cable used in Zhoushan flexible DC transmission project is taken as research object. The finite element software ANSYS is used to establish cable temperature field model. Besides,the theoretic modeling and filed measured data are compared to validate the correctness of the modeling. On the basis of temperature field modeling, the cable ampacity is analyzed. The paper indicates that the cable ampacity can be improved further even in full load, which provides risk assessment for power dispatching during peak hours or maintenance.
