Improvement of the Physical Model of Power Supply Systems Dynamic Loads

摘要

An improved model of Power Supply Systems Dynamic Loads has been developed. This model gives us an opportunity to model electrodynamics processes that go individually in the specific phases of the elements of power supply network. These processes are caused by modes of the operation of power users’ electrotechnology equipment. The model allows us to research asymmetric operation modes of active and reactive loads that occur in the network, to specify the parameters of the current of forward, backward and zero sequence and the Flicker phenomenon, to learn distortions of the current curves of the loads of individual phases, to define the parameters of the higher harmonics that occurred as a result of distortion of the form of the load currents; in addition, this model gives us an opportunity to research and experimentally define the relationship between active and reactive loads of individual phases, to specify the parameters and principles of independent regulation of the compensation devices of reactive power of phases.
