Consideration of the influence of the reliability of elements of the urban electric transport system on its bandwidth

Abstract

The article proposes an approach to assessing the capacity of urban electric transport, which is one of the criteria for a stable resource supply of electric traction, taking into account the reliability of the elements of its infrastructure. By introducing the operational readiness factor as an indicator of reliability, the researcher has the opportunity to assess the impact of failures of these components on the efficiency of the electric traction process, as well as to compare the compliance of the transport line infrastructure with the characteristics of the rolling stock used.

Testing digital instruments and power systems devices

“…A relatively small increase in the cost of testing support can significantly reduce the probability not to detect failures of digital components of relay protection devices based on digital integrated circuits, microprocessorbased components and microcomputers [9,10,11]. As a result, the reliability of operation of digital components of relay protection devices and, generally, power systems increases.…”
