The invention relates to evaluation of effectiveness of processes of transfer and transformation of energy. Method for control of effectiveness of electric power consumption includes determination of losses in electric power supply systems. One determines permitted values for those characterizing specific types of losses brought to existence with power flows relates to transfer of active and reactive power at main frequency to object, presence of non-symmetry and non-equilibrium of systems of voltages and currents, presence of higher harmonics, respective values of weight coefficients for specific consumer: :- characterizes in general power flow part of reactive power transferred at main frequency,- characterizes non-symmetry of system,- characterizes non-equilibrium of system,- characterizes presence of higher harmonics, one determines level of coefficientcharacterizing in general power flow part of useful power transferred; one determines the valueswhere- generalized coefficient of non-quality of electric power in line, one compares those to set values, respectively. The invention provides possibility of differentiation of losses and simultaneous determination of partial losses in power channel by components of non-quality of electric power and due to that increase of accuracy of control. |
