Analysis of Methods for Solving the Problem of Monitoring the Operability of the Electrical Complex of an Autonomous Transport Facility

The article presents materials on the analysis of methods for solving the problem of monitoring the operability of the electrical complex of an autonomous transport facility. Their advantages and disadvantages are determined. The method of a reference voltage divider with symmetry and asymmetry of the divider resistances is considered. The optimal value of the divider resistance is determined, at which the measurement error will be minimal. The results of the error estimation in the reference divider method and the results of simulation modeling of models of the monitoring system of the complex’s operability with symmetry and asymmetry of insulation resistance values are presented. On the basis of simulation modeling, an idealized voltage divider replacement circuit is compiled. The results of the analysis of methods for monitoring the operability of the electrical power supply complex by the criterion of insulation resistance are presented.
