METHOD FOR PRODUCING A TIME-VARYING ELECTRICITY

摘要

The present invention pertains to the field of power generation and electric al transmission lines and may be used for determining the electricity produced, transmitted and used. This invention provides a more reliable definition of the electricity source, of the electricity user and of the section in the electric circuit or electrical transmission line through which electricity i s supplied from the source to the user. To this end, the method involves introducing into the electricity, during and/or after generating an electromotive force, an identifier related to the source or the user, or to at least one of the electrical transmission lines or to at least one of the electricity distributors. The identifier may be introduced into the main frequency harmonic, in one of the highest or lowest voltage or current harmonics. The identifier consists of unipolar and/or bipolar pulses and various combinations thereof, as well as of a time mismatch between the voltage and the current.
