“…The relevance of the topic is explained by the fact that at present the operating conditions of electrical equipment are undergoing profound changes, constantly becoming more complex together with the technological processes in which they are used [1][2][3][4][5][6]. The modes of operation of electrical systems become more dynamic and diverse in nature, which leads to the need to increase the speed of protective equipment.…”

Residential and industrial buildings with large territorial dimensions, have mainly radial power supply schemes, which feed a large number of small and medium capacity 0.4 kV induction motors. For their power supply copper or aluminum cables of small cross-section (with high active resistance) are used. Calculations of electricity losses in such lines show significant values. In order to reduce active power losses in 0.4 kV cable lines, the optimization problem of minimizing active power losses in the radial power supply circuit is solved by optimal distribution of reactive power of a given value between compensating devices. The single-line scheme of power supply of a group of pumps of technological installation of petrochemical production is considered, the mathematical model of the optimization problem on criterion of minimum of active losses in power lines from reactive power flow is made, which limitations are presented as a system of linear algebraic equations. Results of distribution of optimum values of reactive power between compensating devices of asynchronous motors at maintenance of the set tg φ are received. The quantitative estimation of active power loss reduction in power lines at use of capacitor units, which reactive power is optimally distributed, is given.

The paper presents an algorithm for optimizing the conditions of industrial thermal power plants in terms of repairs to their boiler units and turbine generators, which allows to determine the optimal composition of equipment removed for repair, taking into account the fuel used and the season. The algorithm is based on the dynamic programming method, which allows to set models of turbogenerators and boiler units in tabular form, which, when forming the equivalent characteristics of generators or boilers, allows simultaneous determination of the optimal condition of all equipment for a given electrical and / or thermal load of the power plant. The optimality criterion is the minimum of the total cost of the fresh steam needed to generate heat and power. The optimization algorithm and equipment models are specially adapted to the conditions of industrial power plants.
