Reactive power compensation equipment in industrial electric power supply systems generally operates in environment of significant harmonic distortion currents, which are caused by presence of nonlinear loads. A common practice in such cases is the use of compensation schemes, which consist of a combination of filters and capacitor banks. The paper presents study of operation conditions such compensation scheme in the power grid supplying coal mine.

It is proposed to include the principle of distributed generation of reactive power in the basic principles of constructing smart microgrids for non-commercial facilities. Individual reactive power compensation devices should be installed for its implementation at the points of final distribution of electricity networks of buildings and structures.
