Документ Рейтинг конкурентоспособности средств легкой (малой) авиации(ТОВ "Друкарський дім "Папірус", 2010) Яковлев, Анатолий Иванович; Махир Халид Наиф ХилядДокумент Определение решающих распределений параметров модели перспективного планирования(Вища школа, 1983) Голоскоков, Александр Евгеньевич; Капустина, В. А.Рассмотрен один из подходов определения статистических данных параметра модели в зависимости от информированной структуры задачи. Методика, основанная на теореме Каратеодора позволяет свести исходную задачу к эквивалентной. Оптимальное решение последней представляет искомый статистический материал для нахождения закона распределения параметра модели.Документ Алгоритм реконструкции сети аэродромов под старший тип с учетом ограничений на капитальные вложения(Вища школа, 1985) Годлевский, Михаил Дмитриевич; Чернышева, Н. П.; Никифоров, А. В.Предложен алгоритм, позволяющий свести до минимума эксплуатационные расходы. Показано, что специфика рассматриваемой задачи дает возможность многократно использовать простой перебор по отдельным булевым координатам. Достоинствами метода являются простота реализации и применимость к задачам большой размерности.Документ Network-centric technologies for control of three-phase network operation modes(NTU "KhPI", 2017) Sokol, Yevgen I. ; Sirotin, Yu. A.; Iierusalimova, T. S.; Gryb, O. G.; Shvets, S. V.; Gapon, D. A.Purpose. The development of the control system for three-phase network is based on intelligent technologies of network-centric control of heterogeneous objects. The introduction of unmanned aerial vehicles for monitoring of three-phase network increases the efficiency of management. Methodology. The case of decomposition of the instantaneous capacities of the fixed and variable components for 3-wire system. The features of power balance for the different modes of its functioning. It should be noted that symmetric sinusoidal mode is balanced and good, but really unbalanced, if the standard reactive power is not zero. To solve the problem of compensation is sufficient knowledge of the total value of the inactive components of full power (value of the inactive power) without detail. The creation of a methodology of measurement and assessment will require knowledge of the magnitudes of each inactive component separately, which leads to the development of a unified approach to the measurement and compensation of inactive components of full power and the development of a generalized theory of power. Results. Procedure for the compensation of the current of zero sequence excludes from circuit the source, as the active component of instantaneous power of zero sequence, and a vector due to a current of zero sequence. This procedure is performed without time delay as it does not require integration. Only a 3–wire system with symmetrical voltage eliminates pulsations and symmetrization of the equivalent conductances of the phases of the task. Under asymmetric voltage, the power is different, its analysis requires the creation of a vector mathematical model of the energy processes of asymmetrical modes of 3–phase systems. Originality. The proposed method extends the basis of the vector method for any zero sequence voltages and shows that the various theories of instantaneous power three wired scheme due to the choice of a basis in a two-dimensional subspace. Practical value. The algorithm and software implementation for the decomposition of the zero sequence current, which allocated the procedure of obtaining null-balanced vectors of phase and interfacial voltage, calculation of active and inactive instantaneous power is zero balanced mode. The simulation results obtained in the software package Matlab by the method of visual programming in Simulink.Документ A method of complex automated monitoring of Ukrainian power energy system objects to increase its operation safety(NTU "KhPI", 2016) Sokol, Yevgen I. ; Rezinkina, M. M.; Gryb, O. G.; Vasilchenko, V. I.; Zuev, A. A.; Bortnikov, A. V.; Sosina, E. V.The paper describes an algorithm of the complex automated monitoring of Ukraine’s power energy system, aimed at ensuring safety of its personnel and equipment. This monitoring involves usage of unmanned aerial vehicles (UAVs) for planned and unplanned registration status of power transmission lines (PTL) and high voltage substations (HVS). It is assumed that unscheduled overflights will be made in emergency situations on power lines. With the help of the UAV, pictures of transmission and HVS will be recorded from the air in the optical and infrared ranges, as well as strength of electric (EF) and magnetic (MF) fields will be measured along the route of flight. Usage specially developed software allows to compare the recorded pictures with pre-UAV etalon patterns corresponding to normal operation of investigated transmission lines and the HVSs. Such reference pattern together with the experimentally obtained maps of HVS’s protective grounding will be summarized in a single document – a passport of HVS and PTL. This passport must also contain the measured and calculated values of strength levels of EF and MF in the places where staff of power facilities stay as well as layout of equipment, the most vulnerable to the effects of electromagnetic interference. If necessary, as part of ongoing monitoring, recommendations will be given on the design and location of electromagnetic screens, reducing the levels of electromagnetic interference as well as on location of lightning rods, reducing probability lightning attachment to the objects. The paper presents analytic expressions, which formed the basis of the developed software for calculation of the EF strength in the vicinity of power lines. This software will be used as a base at UAV navigation along the transmission lines, as well as to detect violations in the transmission lines operation. Comparison of distributions of EF strength calculated with the help of the elaborated software with the known literature data has been presented also. The difference between the proposed method of monitoring and the existing methods is full automation of the complex control of a number of parameters characterizing the state of the external power grid facilities, as well as its basic electrical parameters. This will be possible due to usage of specially developed software for recognition of optical and infrared images, as well as pictures of lines of equal EF and MF strength.Документ Формирование обслуживания энергосистемы по критерию точности(Харківський національний технічний університет сільського господарства ім.
