Improvement of energy efficiency of agricultural enterprises through the survey of high-voltage transmission lines using unmanned aerial vehicles

Abstract

The paper studies the reliability of transmission lines of Michurinsk district electric lines in Tambov Region. It evaluates the quality of overhead power transmission lines in the support-insulator-wire system and determines the reliability factor of overhead lines. The paper proposes methodological approaches to the survey of power transmission lines using unmanned aerial vehicles. Their use seems quite promising and profitable, since the cost of such work is an order of magnitude lower.

Financing Efficiency Calculation of Energy Enterprises Based on Internet of Things

“…Among them, x ij represents the i input or output index of the jth decision-making unit; max ij and min ij , respectively, represent the maximum or minimum value of the i input or output indicators of the jth decision-making unit [16]. First, through the rDEA package and Deap2.1 software in R language, the input and output data of 30 SME boards and 30 GEM energy companies from 2011 to 2015 were analyzed and processed by the DEA method; finally, the calculation results of technical efficiency (TE), pure technical efficiency (PTE), and scale efficiency (SE) of 60 enterprises are obtained, as shown in Tables 2 and 3 below.…”
