Technical Electrodynamics| Summary: | The technique of analytical construction of coordinate systems in the theory of instantaneous power of three-phase circuits has been developed. Direct relations for the values of coordinate of the vectors of currents, voltage and reactive power in the known and proposed systems have been derived. Obtained analytical expressions allow to compare these coordinate systems by specified criteria. Proposed pwg -coordinate system is adequate to cross-vector and optimization instantaneous power theories of three-phase circuits. Adaptive coordinate system that allows to realize the separate control channel of instantaneous reactive power component has been proposed. Calculation carried out using αβ o -system under symmetrical three-phase power supply, and in the case of unbalance power supply a transition to the proposed γδ o -system, obtained by rotating the previous system around the axis or , should be done.
