The human factor role in the reducing of the power supply reliability

Abstract

The article describes the problem of power supply reliability of hazardous production facilities for Russian coalmines. The authors analyze the accidents in the coalmine external power supply networks for the period from 2014 to 2015 and reveal the weak points in the power supply organization. It is proved that the main cause of power supply violations is the human factor. As a way to increase the power supply reliability the authors propose the algorithm based on the objective quantitative adjectives that eliminates the subjective opinion of the staff and the management of both company-consumers and electric grid companies.
