The scientifically substantiated principles of development of technology of operation of electric systems with traction loads by condition and minimum expenses during their life cycle for urban electric transport are developed. Saving quality criteria that determine resource conservation are generalized. It is proposed to expand the functions of tram wagon laboratories to measure the basic quality criteria. The scheme of expert system for analysis of the state of power supply devices and development of control effects in the analytical centers of control systems is developed. The scientifically grounded principles of the development of the technology of operation of electric systems with traction loads on the state and minimum expenses in the course of their life cycle, in particular the concept of maintenance of power supply devices on the basis of their diagnostics and monitoring, a complex automated system of diagnostics of the contact network and current collectors, means of improving quality scratching and reducing the wear of the contact wire, which collectively solves the problem of resource conservation and allows reducing operating costs 1.5–2 times. Generalized current quality criteria that determine resource conservation. It is established and experimentally confirmed that the basic criteria for the state of the contact network are contact pressing and the coefficients of reliability and economy of current flow. It is proposed to expand the functions in the field of measuring the basic criteria for servicing the contact network by state. The information technologies of an estimation of a condition of power supply devices during their operation on the basis of synthesis of two sources of information are offered: real-time diagnostics and simulation modeling. A generalized scheme of the expert system for analysis of the status of power supply devices and development of control effects in the analytical centers of control systems has been developed. Keywords: electric transport, traction substations, traction networks, diagnostics and operation, technologies, energy efficiency, resource saving.
