Özet:

The operation of most manufacturing processes begins with the electric drive startup, which determines the importance and urgency of optimization of EMS startup processes. In determining the objective function of optimum systems of controlled EMS startup, it was proposed to use the principle of focus on the value added. To implement this approach, various types of input and output products of the EMS startup process were investigated. It is shown that in the analysis of startup processes, it is important to consider accelerated wear of the electromechanical equipment, which is an essential component of the input products of the startup process. The design formulas and models for determining the estimates of input and output products of the EMS startup process, the startup duration were proposed. To overcome the dimensionality problem when dealing with heterogeneous products, it is advisable to use cost estimated of these products. This approach is an economically sound kind of the expert evaluation method. Based on the known efficiency indicator of resource conversion, an expression of the startup efficiency indicator, taking into account the potential economic risks of the startup failure was obtained. By the mathematical modeling methods using Matlab/Simulink, dependences of power consumption, wear and efficiency indicators of the EMS startup process on the control action were obtained. The extreme nature of the dependence of the startup process efficiency indicator on the control action was shown. The results can be used in the synthesis of the optimal control systems of the EMS startup process.
