Monitoring of the Insulation Resistance of the Power Supply Buses of Autonomous Objects

The article presents materials on the development of methods and algorithms for monitoring the insulation resistance of tires of autonomous objects with a two-wire DC power supply system. Equivalent circuits, elementary electric diagrams, systems of equations and solution techniques and mathematic simulation results are described. Estimates were given to the measurement accuracy for autonomous objects power supply buslines isolation resistance control (IRC) systems (ships, spaceships, mines, autonomous transport objects, drones etc.). Algorithms, simulation algorithmic models and all the needed technical requirements for hardware-in-the-loop development with an aim to measure isolation resistance in the power supply circuit were prepared. Buslines isolation resistance measurement techniques were enumerated for buslines in different electrical energy complexes, autonomous objects and systems.

I. Introduction

Life time, electrical safety and reliability rate are the main objectives needed to allow autonomous objects constant operation. Autonomous objects electrical devices safe maintenance and systems reliable power supply are the main requirements applicable to electrical facilities [12]. These requirements are connected to the most significant parts of the system – isolation resistances.
