Abstract

The automated design of the power supply system of LLC "Barlinek-Invest" was completed with the use of technical, mathematical and software automation of designing with the help of which the technical, technical and economic and optimization design calculations were carried out. As the main means of automation of design used: the electronic processor EXCEL, mathematical CAD Mathcad, word processor WORD and graphic CAD Microsoft Visio. Using the electronic processor Excel, the calculation of the average and estimated loads of the workshops and the enterprise as a whole, the optimal power of transformers of the TPP was found, the section of the external cable line and cables of 10 kV of the network of the in-plant network were determined on the criterion of the minimum cost in the ENP. A network center has been found and the appropriate location of the CTR is selected. Using mathematical CAD Mathcad, the calculation of the capacities of compensating devices was performed.
