摘　　要：介绍ETAP软件在铁合金项目工程设计中的应用,利用ETAP软件的短路计算模块能针对复杂的系统快速准确地计算出短路电流,star保护及配合模块能输出TCC曲线视图。建立铁合金项目10 kV配电系统的单线图模型,完成短路电流计算和保护定值计算,并利用TCC曲线验证上下级的配合。Application of ETAP software in the engineering design of ferroalloy projects is introduced.The short-circuit calculation module of the ETAP software can beused toquicklyycalculate the short-circuit current of complex systems,and the star protection and coordination module can be used to output the TCC curve view.A one-line diagram module of the 10 kV distribution system for a ferroalloy project is created,the short-circuit current calculation and protection value calculation is completed,and coordination between upper and lower levels is verified using TCC curves.
