Non-intrusive method of conducting energy audits of electrical power facilities.

The paper describes non-intrusive load monitoring (NILM) during energy audits of electrical networks of 0.4 - 10 kV consumers. The NILM method allows you to remotely determine the individual parameters of electrical networks and installations of consumers (industrial, municipal, agricultural, etc.). Measurements do not require access to individual installations, which provides a convenient way to collect parameter data compared to placing meters or sensors on each installation. Everything happens similarly to the "black box" method, and the subject of analysis is the total parameters of electricity at the input of the enterprise. Unlike the classic "black box", the structure and internal electrical circuit of the enterprise, passport data and possible operating modes of equipment and electrical networks are known here.
