海洋钻井平台上的各种电气设备构成了一种特殊的电力系统。为了对平台上各种电缆进行选择和计算各母线上的短路电流。我们开发了一个“平台短路电流计算和电缆选择软件”。它基于Windows 95操作系统,完全用Visual Basic5.0开发,可以进行钻井平台电力系统的绘制、短路电流的计算、各种电压降校核以及电缆型号的选择。作些适当修改,它也可用于其它电缆配电网的计算。 A variety of electrical equipment on the offshore drilling platform forms a special type of electrical system. In order to select a variety of cables on the platform and calculate the short-circuit current on each bus. We have developed a platform short-circuit current calculation and cable selection software. It is based on the Windows 95 operating system and is fully developed with Visual Basic 5.0 to draw rig power systems for the rig, calculations of short-circuit currents, various voltage drop checks, and cable model selection. With some modifications, it can also be used for the calculation of other cable distribution networks.
