Abstract

The article covers the issue of simulation of a static semiconducting compensator of the total power inactive components operating in AC power single-phase network for a spot resistance welding machine. The authors showed the wide use of resistance welding in modern production. The disadvantages of modern power supplies of resistance welding machines are defined according to their energy efficiency. The authors made a conclusion that it is possible to reduce energy consumption by 20-40% using special devices - semiconducting compensators. Since both the resistance machine and compensator operate at high currents and voltages, and the cost of their electrical components is large enough, the task of creating a computer simulation model of the "Industrial network - Semiconducting compensator - Resistance welding machine” system was set. As a tool, the Matlab Simulink software was selected, because it allows you both to simulate the electrical elements and perform mathematical and logical operations necessary to describe the algorithm of control system work. The article represents all simulation model parts: the network, the compensator power circuit, the compensator control system, the resistance welding machine. The authors described in detail the process of selection of a particular Simulink block for the model implementation and introduced mathematical expressions forming the basis for the work of compensator key management system and the basis for the resistance machine simulation. The authors carried out the simulation of the system work and presented the results in the form of timing diagrams of currents and voltages. System operating troubles are displayed when the nominal values of electrical elements of the compensating device are selected improperly. The authors made the conclusion on the possibility of applying the developed model for the study of various modes of the compensator operation, as well as for selection of nominal values of its components.
