Annotation

    The advantages of modern digital methods for estimating the parameters of electric power flows in three-phase industrial networks are considered. It is noted that the key factor in the optimal management of electricity flows is the correctly chosen methods for measur­ing the parameters of the electric power flow. It is indicated that the deviation of power quality indicators from normalized leads to an increase in active losses and consumed reactive power, to a decrease in the service life of electrical equipment, adversely affects automation systems, relay protection, telemechanics and communications, etc. The application of digital methods for esti­mating the parameters of electric power flows in three-phase industrial networks is proposed, an algorithm and methods for their measurement are given, and the advantages of their application in the conditions of Tajikistan are justified.

 

Key words
