Mine electrical power systems. Transients protection, reliability investigation, and safety testing of mine electrical power systems. Volume III--optimal design of mine electrical power systems. Open file report (final) 24 Jun 74-15 Aug 78
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 tipology of a coal mine electrical system changes continuously due to the movement of locomotives on the track. In 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 mode for a low-voltage power cable. Results from experimental verification of the model are also presented.
