Sirotin Y. Compensation and account of reactive power in electrical systems with asymmetrical modes

The object of research is electric 3-phase process at the point of consumer connection with imperfect load to the 3-phase at asymmetrical voltage.The purpose of research is the decision of scientific and technical problems of the general theory of power, a single integrated approach to compensation and accounting for the inactive components of apparent power for optimal energy consumption at the point of load connection to the network with asymmetrical voltage. Methods: methods of electric circuit theory and vector algebra of complex 3-dimensional vectors (3- complex), matrix theory, methods of mathematical modeling and optimization, method of orthonormal basis. Theoretical and practical results: the creation of vectorial mathematical models of 3-phase power supply and power consumption modes. Methodology for calculation of additional losses in an unbalanced mode allows to estimate the losses caused by the symmetry and asymmetry of reactive elements active and reactive elements connected electrical equipment. Scientific novelty: It first time is obtained complex form of vector instantaneous power. It is established its connection with the (known and new) integrated energy performance of non-symmetric modes. Degree of implementation: the results of the implemented of "Tess" and LLC "Khartep" (Kharkov), and are used in the educational process of NTU "KhPI". The field of application: enterprises, research and design institutes, which are involved in the design and manufacture of compensating devices, accounting means of electricity supply systems.
