Power processes quality estimation and compensation for poor quality in low-voltage electric networks

A method of power processes quality estimation and compensation for poor quality in industrial low-voltage electric networks is substantiated. Calculation relations for spectral presentation of power components and quality factors of electric power are improved in accordance with p-q-r-theory of instantaneous power. The structure of compensating device is grounded and a higher efficiency of nonlinear distortions compensation compared with the basic variant of p-q-r-theory is confirmed.
