海洋石油平台中压电力系统中性点接地方式研究

随着电力系统的复杂性和规模的不断扩大,使得海洋石油平台电力系统的电容电流随之增加,对中压系统的接地方式提出了新的要求。本文介绍了海洋石油平台常用的几种接地方式及其特点。最后以渤海某油田项目为例,介绍如何根据中压系统的电容电流来选择适合的接地方式。

Methods of Neutral Grounding in Medium Voltage System on Offshore Oil Platforms

With the increasingly expands of power system’s scale and complexity,the capacitive charging current in power system on offshore oil platform is increased simultaneously,meanwhile the grounding method should be considered.Firstly,the paper introduces the methods of neutral grounding on offshore oil platform in common use,then it explains how to calculate the earth fault current and finally gives grounding method in medium voltage system applied to Bohai offshore platform project.
