Based on the representations in barycentric coordinates on a balanced supply line-to-line voltages triangle the resulting complex-plane static phasors of the zero sequence voltage and of the related unbalance factor are obtained for the balanced mode of the three-phase supplying. It is supposed that the voltages and currents are sinusoidal. The suggested formulae calculations require only RMS voltmeter readings of the three line-to-neutral load voltages and could be used as a practical engineering tool to implement a three-phase load circuit monitoring, diagnostics, protection and voltages unbalance compensation. Physical interpretation of the neutral bias voltage phasor barycentric coordinates, corresponding to the coefficients of participation of the individual phase loads in this bias voltage generating, is also presented as the functions of the phase loads electrical admittances parameters.

The article presents an algorithm of voltage coordinated management in distributive electric railway networks using the sources of the reactive capacity based on the agent approach. Voltage management in the electric network is implemented by the managing system coordinated between all local regulators inside the controlled zone. The authors present an approach to the coordination of the local regulators operation based on their possibilities ranking by the type of the action to achieve the global management purpose. By means of operational voltage management in the electric network it is proposed to use the linearization of the management task from behind the almost linear dependence of the comparative powers growth on the loads of separate units as a matrix of the sensitivity. The authors conducted the simulation and mathematical modeling of the implementation of the proposed algorithm in the distributive electric railways network and there.

The paper covers the design of an integrated brushless excitation direct-current generator (IBEDCG), where the exciter and the main generator are located in the same magnetic system. When sizing the active part of such machines, one must choose and distribute the electromagnetic loads: magnetic flux density in the main-generator and exciter gap, and stator/rotor line current density. The research team investigated the magnetic-field factors (the estimated pole overlap factor, the form factor of the excitation flux and the EMF form factor) as a function of the exciter excitation winding design and magnetic-system saturation. The article compares the results of the FE simulation and analytical calculation of these coefficients. The suggestions on choosing the electromagnetic loads ratio of the exciter and the main generator are given. The paper provides specifications of a prototype generator for a special vehicle on tracks.

Being exceptionally innovative, the development and research on high-speed magnetic levitation transport (MLT) has received much attention worldwide. The literature review shows an increased activity in this field in Russia over the last two decades. Regular research are conducted in Russian University of Transport, Saint-Petersburg and Rostov State Transport Universities. The status of MLT development makes it possible to employ Linear Induction Motor (LIM) for the traction of the maglev vehicles. The systems of high-speed MLT with tractive LIM use conductive bus bars as an anchor called secondary element (SE). The currents in the three-phase winding of the LIM inductor create a traveling magnetic field intersecting the SE conductive part and inducing the electromotive force (EMF), which in turn causes the flow of secondary currents. The interaction of the traveling magnetic field with the induced SE current will give rise to LIM traction. Finding the current in the LIM inductor is crucial for determining the tractive effort. The paper focuses on linear induction motor with transverse magnetic flux (LIMTMF). The conducted research was aimed at considering and solving the problem of defining the inductor current in the middle and frontal parts of the LIMTMF winding. The obtained results made it possible to increase the reliability and precision of the tractive effort calculations.

The most common consumer of electrical energy in the power system are asynchronous motors. In view of their widespread relevance, the task of maintaining static load stability is constantly increasing. At the moment, the limits of static stability are determined on the basis of nameplate data, which can lead to significant errors. The use of up-to-date information on the electrical parameters of the asynchronous motor makes it possible to increase the accuracy of calculations and the adequacy of the control actions produced by automatic equipment. The article proposes a method of parametric identification, which allows determining the electrical parameters of the asynchronous motor in operational modes. The method is based on determining the parameters of the system of Park-Gorev complete equations by a numerical method. The error of the proposed method is less than 1%. The introduction of low-frequency noise with amplitude of 1% of the main signal increases the accuracy of the method to 5%. The introduction of high-frequency noise with amplitude of 0.5% of the main signal increases the error of selected parameters to 7%.

The signals of voltage and input current of electrical networks nowadays are not sinusoidal. Currently, among the parameters of reactive power, the most interesting is the reactive power of the fundamental component of the spectrum. At the same time, to measure the parameters of the reactive power of the fundamental component, the approaches to measure sinusoidal current and voltage signals can be used. Most measurement methods of the sinusoidal signal reactive power are based on a phase shift of the voltage at an 90 degrees angle and the subsequent application of one of the well-known methods of the active power measurement. Among the known methods of the measurement of the reactive power of a sinusoidal signal can be distinguished: the time delay method, the integration method, the preliminary differentiation method, and the integration-differentiation method. The main cause of the errors in the considered measurement methods is the effect of the voltage and current harmonics and the input signal frequency deviation from the nominal value. In this paper, the analysis of the effect of these parameters on the measurement error of the reactive power of the fundamental spectral component for the above measurement methods was performed. The obtained analytical relationships allow estimating the reactive power measurement error when the input frequency deviates from the nominal value. The application of a discrete unit delay block for as a time delay block is considered. For the integration method the implementation based on a first-order digital integrator is considered. For the differentiation method, the implementation based on a first-order digital differentiator is considered. Simulation modeling was performed by Matlab and Simulink packages, which confirms the validity of the analytical expressions obtained. The comparison of the considered methods from the point of view of implementation complexity and error of reactive power measurement is made. It is shown that among the considered measurement methods the integration-differentiation method has the smallest error.

The article discusses the on-site optimization algorithm of industrial thermal power plants with heterogeneous generating sources with capacities ranging from a few to tens of megawatts. The optimization algorithm is based on a dynamic programming method in combination with a modified sequential equivalent method. The optimization criterion is the minimum of the reduced cost of steam required for the generation of electrical power, going to the heating and production selections, as well as its own needs. As a result of the optimization task, the economically feasible loads of generators and power boilers are determined. The main initial data for optimization are technical and economic models of turbine generators and boiler units, which represent the dependence of the active or thermal power on the cost of a unit of fresh steam. The models are constructed in tabular form and take into account the operating characteristics of power plants. Optimization calculations are carried out for normal, repair and after-failure operation of electrical installations.
