A generalized approach to localization of sources of harmonics in a power system

Finding an answer to the question who is responsible for the generation of harmonics in power system is an essential problem especially in the conditions of the energy market. In the paper, the method which unlike other methods is reliable and does not require exact knowledge on parameters of equivalent circuit representing the utility and customer sides, is considered. This method utilizes the specially-defined rate, being generalization of the so-called voltage and current rates. Using the generalized localization rate, the localization of sources generating harmonics in voltage differs from the localization of sources generating harmonics in current by other definition of areas of possible changes of variables from which the mentioned rate depends. In the paper, the relatively-simple way of performance of required calculation is also described. As the result of the presented consideration is standardization and simplification of localization of sources of harmonics in voltage or current in a power system.
