Abstract
The article shows that the data of the collected by the automated commercial electricity metering systems are an ensemble of daily realizations of random processes of power consumption of the power supply system. The main purpose of using automated systems of commercial and technical electricity metering is to reduce power consumption. But it is noted that the efficiency of using data of the automated commercial electricity metering system, efficiency and proper management of energy consumption depends on the operators of automated workstations. Considering the rapid improvement of both technical means and mathematical methods that can be applied to address energy efficiency issues, there is a need to transform remote data collection systems from electricity meters, taking into account quality, into a measuring and information structure capable of not only collecting data from meters, electrical energy, but also analyse them. The main method for detecting undercounts is given - the balance method. On the basis of the balance method, it is proposed to automatically calculate the unbalance for each section of the 6, 10 or 110 kV line of the main step-down substations and distribution points, taking into account the number and accuracy classes of commercial metering and technical metering devices. It is proposed to balance the load on the results of calculations performed by automated commercial electricity metering system in order to reduce energy losses and reduce payment for electricity. It is proposed in the work that the automated commercial electricity metering system should calculate the coefficients of form, maximum, load, as well as other morphometric characteristics of the graphs of electrical loads. The work drew attention to a number of problems arising in the calculation of these parameters: electronic meters measure the data necessary for calculations but not with the specified discreteness and, most importantly, their measurement of these parameters of the quality of electrical energy is not metrologically certified, therefore, such data can only be relied on as background information.
