水泥生产线电气系统短路电流计算及相关电气系统要点

Calculation of short-circuit current of electric system in cement plant and the points

电力系统日常运行过程中,时常会发生短路故障。以吉木萨尔水泥线(配套余热发电)全厂电气一次系统为例,用叠加法进行了其最大运行方式短路电流(两台主变分列运行方式)的计算,并对电气设备额定值进行了选择校验。

Short-circuit malfunction happens frequently in daily running of power system. Electric primary system of Jimusaer Cement Produetion line with waste heat power generation system was took as example, the short-eireuit current of max load operation——two main transformers run simuhaneously was calculated, and the rating walues of some electric equipments was verified.
