“…The effect of distributed generation on short-circuit currents depends on the type of generator and how it is connected to the power grid (directly or initially converted using an inverter [24,25]. In the case of rotating generators directly connected to the grid (3), the generator impedance Z dg = R + jX in short-circuit mode can be determined as follows [26,27]:…”

The article considers electrical complexes with power plants of small capacity. The influence of power generation sources on short-circuit current distribution has been investigated. Reduced sensitivity of back-up current protection and dependence of current distribution on power plant capacity are revealed. Recommendations for minimizing false operation of short-circuit protection in networks with distributed power generation are proposed. An algorithm for adaptive current protection, which uses graph theory to determine the stages of selectivity of relay protection based on finding the shortest Dijkstra path and calculation of equivalent resistance in networks with multiple sources of power generation, which provides selec-tivity and sensitivity of current protection when changing the generated power of generators and the structure of the distribution network is pre-sented. The algorithm uses communication lines with a central control unit to monitor the distribution network and update the current triggering of the relay protection in accordance with changes in the structure of the power grid. The proposed system is designed so that it can respond to dynamic changes in the structure of the network and the state of operation of power plants. Simulation modeling in the Matlab/Simulink software package was performed and the results of the algorithm are presented.

“…Thus, electric motors with parameters which meets the following requirements, can be used for operation as part of in-wheel motor: high torque at low speeds; wide speed control range; high coefficient of power density. Electric motors which corresponds to mentioned above criteria are presented by the following types: asynchronous electric motor [4,5], permanent magnet synchronous motor [6,7]; brushless DC motor [8]; reluctance motor [9]. Based on the comparative analysis carried out in work [10], the permanent magnet synchronous motor (PMSM) is the most suitable type of electric motor forin-wheel motors.…”

This article describes an electric drive system’s topology with a permanent magnet synchronous motor for a wide speed range applications. Topology consists of a synchronous motor with permanent magnets (PMSM) and two inverters connected to the beginnings and to the ends of the PMSM’s stator windings. The first inverter is connected to a storage battery, while the other one to a floating bridge capacitor, which acts as a back-EMF compensator. The article proposes electric drive system topolo-gy and its control algorithm. Simulation modeling was implemented by the MATLAB/Simulink software package. Simulation results shows that the proposed electric drive system, in comparison with the standard topology with a «star» stator windings connection, is able to increase the maximum speed of PMSM in the field weakening mode by 17%. The maximum achievable torque on the rotor shaft at the maximum speed of the PMSM motor was increased by 16.6%. Also, developed topology allows to in-crease the speed range in the constant torque mode by 34%.

One of the important parameters of using the hydraulic transport system in mining enterprises is considered. A method for regulating the ground pump drive and a computer model of the drive power stabilization system are proposed. The simulation was performed in the Scilab program. The performance of the proposed model was checked. The results of simulation with different values of the current and torque are shown. The efficiency of the proposed method for regulating the ground pump drive is evaluated.
