Horenko D. Estimations of intermediary processes in local systems are electrical testing with geared rosoregenera generators.

In the dissertation the complex analysis of the peculiarities of functioning of local power supply systems (LPSS) is carried out taking into account the modern requirements of the Smart Grid concept and the comparative analysis of methods of estimation of exchange processes in LPSS with dispersed energy sources is performed. The need to extend the known LPSS system to adequately assess the EMC levels in the LPSS with the requirements of the Smart Grid concept and to estimate the energy flow rates using known indicators is justified. The analysis of exchange processes of LPSS under the influence of different types of impulse disturbances and sources of non-sinusoidal voltage and current cau¬sed by the peculiarities of modes of operation of both individual elements and the system as a whole for single and three-phase cross sections of LPSS is carried out. New relationships were obtained to evaluate the effect of non-sinusoidality and to take into account the ripple coefficients on the nature of the exchange processes. The analysis of the exchange processes in LPSS has been carried out taking into account the real characteristics of the elements with electromagnetic bonds (tra¬nsformers, reactors, transmission lines, etc.) and new relationships have been obtained, which link the exchange power and the coefficients of magnetic coupling for one and three-phase LPSS operating in both sinusoidal and non-sinusoidal modes, as well as in symmetric and asymmetric modes. A specialized software module and regulatory and methodological support for the extended energy audit using exchange power have been developed and tested. The proposed regulatory and methodological support makes it possible to: determine the exchange power and the proportion of mutual influence in an arbitrary intersection of LPSS, taking into account the peculiarities of their configuration, mo¬des of operation of individual elements and LPSS as a whole; to obtain informat¬ion on exchange processes in the LPSS with different levels of information support; to adequately take into account the peculiarities of the flow of modes in the LPSS, in particular, the bidirectionality of electricity flows and to determine their real distribution in the elements of LPSS.
