For the construction of subsystem for power line diagnostic states of distribution networks as a part of AMRCS

Abstract

At present, in order to automate and informative processes in distribution zones (DZ) with a voltage of 0.4 kV, new technologies have found wide application in the form of automated meter reading and control system (AMRCS). However, as part of these information systems, there are no technologies focused on solving diagnostic problems. The report proposes methodological and algorithmic foundations for constructing a subsystem for diagnosing the states of wires of the main lines of DZ. Diagnostic criteria are formulated based on the assessment of the level of their run-out. The research results are aimed at improving the existing AMRCS and increasing the reliability of distribution networks.

Algorithmic foundations of automated monitoring of commercial and technical power losses in distribution networks

“…The analysis of the functional structure of existing ASCMPCs shows that they do not solve the tasks of separate identification and operational monitoring of technical and commercial power losses in the network [3], as well as do not perform optimization tasks [4][5][6][7], which reduces their efficiency and technical and economic performance of distribution companies. In particular, this is due to the fact that to date, adequate and constructive methods for solving the above problems have not been sufficiently developed, taking into account such factors as the presence of unauthorized power withdrawals (UPW) in the network [8 -10], and the asymmetry of PDN operation modes [11][12][13][14]. The problem also lies in the fact that most PDNs belong to the class of large dynamic systems, which have a complex structure and function under conditions of incomplete information about their states and parameters.…”
