“…As the previous researches showed, suitability of Arctic regions for wind energy generation force the extensive interest of scientific communities and manufacturing companies in overcoming following problems [7][8][9][10] . On the one hand, rotor blades should be designed in appropriate way to survive regular icing, which in Arctic can occur up to 20% of the time during the year.…”

The paper addresses approaches to increasing the efficiency of wind turbines operating in autonomous mode in Arctic regions. Such type of wind turbine operation is related to fluctuations of the generated power, that negatively affects grid power quality. The increase of wind turbines efficiency is achieved by the utilization of current reserve of power converter, which is a necessary part of megawatts-sized wind energy generation unit. The developed Simulink model of the wind turbines, built according to two of the most suitable for megawatts-level power generation topologies, was used to determine their power output depending on the wind turbine’s rotor speed and the wind speed. Obtained power profile was then used to determine the amount of free current reserve depending on the wind speed, which has verified the ability of both wind turbine topologies to efficiently improve grid power quality, therefore leading to reduction or absence of the necessity to install additional power equipment for the compensation purpose.

“…Use of piezo actuators becomes of special importance in the development of spacecraft where actuation devices should feature rather small mass and size characteristics, possess substantial developed force and allow a separate control object included into the technical system performing precision movements (Matveev et al, 2018). For instance, to arrange the communication channel between the earth-based station and the spacecraft is necessary to accurately form the antenna pattern, since even its smallest deviations can result in substantial losses in signals reception or transmission (Frolov et al, 2018;Kiseleva et al, 2018;Medvedev et al, 2018;Yenuchenko, 2018). Accuracy of the above-mentioned antenna pattern forming can ensure getting the transformed antenna where control of the radio-reflective surface shape is ensured by changes in the cables' length (Zhengrong et al, 2014;Yiqun et al, 2016).…”

“…For calculation of short circuits in a circuit with power transformer with a voltage regulator device [1][2][3][4][5][6][7][8], the well-known method described in [9] and [10] uses assumptions, according to which transformer resistances are calculated only for the average and limiting taps of the voltage regulator. This simplification leads to a significant error in calculation of currents during short circuits, which unjustifiably increases the unbalance of the differential protection of power transformer and reduces the sensitivity of the current relay protection and automation (RPA).…”
