1) underground cable system
地下电缆群
1.
Finite difference method (FDM) is used to divide the transient temperature calculation process of underground cable systems into discrete groups of transient time step,and finite element method (FEM) is used to calculate each time step-temperature distribution of underground cable systems,and the transient temperature distribution of underground cable systems is calculated.
利用有限差分法将地下电缆群暂态过程分为离散的时间步,然后利用有限元法分析每一时间步的地下电缆群温度场分布,给出了土壤直埋电缆群的暂态温度场分布。
