Abdel' R. Digital system of tasting and regulation of theree-phase networks of industrial enterprises at assymetrical loading

The subject of research is "Three-phase networks with asymmetric operational model". The goal of research consists of both of working out of methods and means of monitoring and control of asymmetric modes of thee-phase network and construction of controlling devices on their base, which make possible to execute balancing and regulation of reactive power in concrete time at arbitrary load if there are higher harmonic modes. Research on the basis of theory of information, random probability processes, linear lumped parameter systems, methods of mathematic modeling. Digital methods of control of symmetric thee-phase systems, based on the correlation signal processing have received further development. The method of dynamic error estimation of the first type for digital devices of measurement of asymmetry of types of resistance was developed. Methods and means of symmetry of three-phase networks at random alternation of loads were improved. Operating algorithms of balancing of three-phase networks, which m ake possible to carry out synthesis of framework diagram of balancing devices in case of lack of higher harmonic modes of power supply systems were improved. Framework diagrams of balancing devices with different information parameters and control techniques of parameters in balancing devices are designed. The sphere of use is three-phase networks of industrial enterprises.
