- Abstract
Introduction. Conducting a comprehensive analysis of methods and tasks for ensuring the effective implementation of innovative thermal compensating devices. Materials and methods. Physical and mathematical modeling of processes, the principles of the theory of automatic control, the theory of fuzzy logic were used. Results and discussion. The compensation of overhead power lines wires sag creates conditions under which it is possible either to increase spans, or to reduce the height of the towers while preserving the existing estimated spans. As a result, the specific consumption of the supports, linear fittings, insulation is reduced, and the time for construction of the power lines is also reduced. Taking into account the existing norms, it is possible to increase the span of the power line of different voltage classes by 7-10%. As a result of the conducted research, a method for calculation and optimization of existing devices for thermal compensation of power lines wires sag has been developed. A multifunctional device for compensation of temperature arcs of sagging of power lines, which allows to optimize both working and projected power lines is proposed. Conclusions. The results of this work should be used in electrical networks with overhead power lines of all voltages. The Ukrainian thermal compensator is a new class of equipment for power lines, which solves the problem of temperature extension of wires, using a material that responds to the temperature changes by changing its geometric shape and size and is more reliable than the American one.
