ADDITIONAL POWER LOSSES IN ELECTRICAL NETWORKS AT ASYMMETRICAL LOADING
Keywords:
Asymmetrical loading, capacity and electric power losses, quality of the electric powerAbstract
In this article are presented the issues of ensuring the power quality and assessment of additional losses using the load unequency coefficient. An analysis is made of the change in the relative magnitude of power losses in the 0.4kV network depending on the magnitude of the load unbalance in phases. Voltage asymmetries can occur when the load distribution between the phases is improperly distributed in two cases. In real life, of course, there is a combination of these two cases for all phases simultaneously, but it will be useful to consider them separately, considering them as limiting cases, from which the real asymmetry in the network is formed.
