摘要
介绍了短路计算在石油钻机电控(SCR/VFD)系统中的重要性以及计算要求,以常规配置用于海上钻井船或平台的ZJ70DB电控系统为例,叙述了短路计算的关键因素、各器件阻抗的确定方法,介绍了电缆电感的算法以及影响其大小的因素;按照"品""一"型常规布法进行了两种情况下电感的计算以及各短路点短路参数的计算。
The importance and calculating requirements of short-circuit calculation in the electric control（SCR/VFD）system of oil drilling rigs were introduced. Took ZJ70DB electric control system conventional configured inoffshore drilling vessel or platform for example,the key elements of short-circuit calculation and determining methodsfor the impedances of each device were described,the algorithm and the factors that affect the size of the cableinductance were introduced;in accordance with layout as triangle or in-line,the inductance calculations and shortcircuitparameters calculation of each short point in both cases were carried out.
