Abstract: A software program ZYM (AutoCAD application) for calculating of LPS, grounding and EMC problems of power substations has been developed. The program consists of a calculation kernel and an AutoCADbound interface (COM-technology). Advanced methods and programming technologies are used. High performance is reached with the use of Intel Math Kernel Library. The results of calculation get visualized by 3D plots, and dynamic processes are animated. The example of LPS, grounding and EMC calculations of electric powe… Show more

Traditional analytical methods for calculating and designing of grounding devices (GDs) in heterogeneous soils can lead to results that do not correspond to those obtained in practice. The empirical coefficients used in calculations of grounding systems given in various literature sources do not always give an explicable and significant discrepancy with the same initial data. In this paper, some well-known methods for calculating the spreading resistance of GDs are considered and the obtained results are compared with experimental data. It is shown that the recommendations and algorithms for calculating the resistance of GDs, presented in the well-known reference literature and regulatory documentation, do not give full and correct description for grounding devices installed in heterogeneous soil. In particular, it is shown that such a factor as the proportional ratio of soils with different resistivity practically does not affect the final result. This fact may mislead specialists, since the results obtained may differ significantly from what is observed in practice after the installation of GDs. The study proposes a calculation method and shows a fairly good convergence of the results with experimental data, and defines a further direction in optimizing calculation methods GDs.

This article deals with the development of tools for configuring and modeling modular information and measurement systems. The use of standard solutions for the industrial facilities automation requires the use of special tools – configurators. It is advisable to use one of the popular CAD systems, for example, AutoCAD, as the basis for creating the configurator. Authors analyse various ways for creating and managing AutoCAD projects using built-in tools and external programs. It is shown that ObjectARX environment is the most powerful means of solving such problems, providing maximum integration and performance. The results obtained by the authors during the modular systems configurator development allow recommending ObjectARX for creation of specialized CAD systems based on AutoCAD.
