Abstract
This report describes the analysis tools developed at West Virginia University that can be implemented to optimally design coal mine electrical systems. The basic analytical tools for all power systems are the load-flow and short-circuit analysis. Well-known programs have been developed for analysis of ac transmission and distribution systems, but they are not applicable to a system that has combined ac-dc distribution, such as a coal mine power system. Furthermore, the topology of a coal mine electrical system changes continuously owing to the movement of locomotives on the track. In the first section of this report, algorithms for carrying out load- flow and short circuit analysis of a coal mine electrical system are described. Results from the study of a typical coal mine system are presented. In the second section, a method is described to optimally size power cables for cyclic loads. This method is based on the development of a thermal-electric model for a low-voltage power cable.
