Abstract
The article deals with the possibility to optimize operation modes of electric transmission lines (ETL) by means of a voltage controller of thyristor transformer type (VCTT). One of the possible ways to implement hardware concept Smart Grid and FACTS technology was demonstrated based on optimization factors of parameters such as ETL conducting capacity, electric power losses, its quality, operational and modernization cost of power facilities. VCTT main technical specifications and energy parameters, considering the power transformer magnetic core effect were considered. For its identification graphic environment of MATLAB Simulink imitation simulation, upgraded LabVIEW, LTSpice programs and “powergui” blocks, “Hysteresis Design Tool,” “Fourier 1–40” were applied. Possibility of ETL operation modes optimization in case of its charge capacity compensation, when implementing specific operation algorithm of VCTT force multipliers, was demonstrated. As a consequence of computer-based and physical simulation, data of transformers VCTT reactive power consumption, taking into account the magnetizing curve and limitation imposed to equipment selection and its operation modes, were obtained.
