基于ETAP软件的电力系统短路电流计算及其在大型油库配电系统中的应用

The Short-circuit Current Calculation of Electric Power System based on ETAP Software and Its Application to Electric Distribution System in Large Oil Depot

电力系统短路电流计算是电力系统设计的重要环节之一,基于ETAP软件建立了大型油库配电系统模型,完成了最大运行方式下和最小运行方式下的短路电流计算。为电气设备校验及电力系统继电保护设计提供了准确的基础工程数据,为电力系统的顺利投产和平稳运行提供了有力的技术支持。

The short-circuit current calculation in electric power system is an important part of the electric system design. An electric power distribution system model in large oil depot has been built in this paper based on the ETAP software. The short-circuit current calculation has been finished for the maximum and minimal operation mode of the electric power system. The proposed method provides the accurate basic engineering data for the designs of the electrical apparatus calibration and relay protection. It also gives helpful technical support for the safe and smooth operation and production of the electric power system.
