Digital control of operating costs of 10 kV overhead power line as a way to improve the efficiency of its operation

Abstract

In today’s context, the effective functioning of infrastructure cannot be achieved without a properly regulated financial support mechanism. Maintaining an optimal balance between stimulating and supporting operating costs during the operation of 10 kV overhead power lines (OHPL) is an important technical and economic task. Currently, its solution confuses the financial and economic services of many electric grid enterprises, due to their limited technical and personnel capabilities. This circumstance does not allow them ensuring the highest level of efficient operation for each 10 kV OHPL which ultimately leads to waste of money, labor resources and spare parts. The authors propose solving the problem with the help of modern achievements of scientific and technological progress in the field of automation, microprocessor technology, as well as digital information and telecommunication technologies. The integrated use of this toolkit will allow electric grid enterprises to quickly ensure the optimal ratio of operating costs for each of the 10 kV OHPL when its operational indices will not go beyond acceptable values. At the same time, as controlled operational indices, it is proposed to use the duration of events associated with the occurrence of single-phase ground faults in each of the 10 kV OHPL. This paper discusses a circuit solution that makes it possible to implement an adaptive automatic control system in practice, and also discusses issues related to the specifics of its functioning including the use of a self-learning neural network algorithm.
