中压岸电系统分布电容的估算*

摘要

The paper combines the specific parameters of medium voltage ship connecting shore‐to‐ship power system , including size of cable ,length of cable and parameters of transformers .The empirical formulas is used to estimate the distrib‐uted capacitance on medium voltage shore‐to‐ship power system .According to three different ways of shore‐to‐ship power ca‐ble laying ,different principles and empirical formulas are used to estimate the capacitance respectively ,and finally choose the situation of laying in ground to estimate the capacitance of cable on land and boat .And combining the specific parameters of transformers on medium voltage ship ,the paper reaches estimated value of the total distributed capacitance voltage shore‐to‐ship power system .%论文结合了中压船舶连接岸电系统的具体参数，包括电缆尺寸、电缆长度和变压器参数，利用经验公式对中压岸电系统的分布电容进行估算。论文针对岸电电缆的三种不同铺设方式，运用不同的原理和经验公式分别进行了估算，最后选取了埋地的情况，给出了陆地电缆分布电容估算值。并结合中压船舶变压器的具体参数，得出了中压岸电分布电容的总和。
