海洋工程项目电气系统短路电流计算分析

摘要

为保证海洋平台重要电气设施能够承受短路冲击,确保海洋平台的安全生产,以基础研究为主,建立海洋石油平台电力系统数学模型,论述海洋平台短路电流计算方法,在EDSA软件里对短路电流计算校核,发现所采用的忽略计算可以满足电气设备选型及保护要求.其理论分析可为海洋石油工程设计人员提供参考.%It is a very important issue to offshore engineering staff that how to insure electrical facilities successfully with stand short-circuit electrical shock and ensure the safety of offshore production.The priority is given to basic research,the mathematical model of electrical system of marine engineering project is built,the method of calculating short-circuit current of offshore platforms is discussed,and the short-circuit current calculation is verified in the EDSA software.It can be found that the ignored calculation can meet the requirements of electrical equipment selection and qrotection.Theoretical analysis of these provide a useful reference for designing staffs working on the offshore oil engineering.
