Využití SW prostředků pro výpočty technických ztrát u vedení přenosové soustavy

Abstract

Diploma work is focused on solving problems technical losses in the transmission system lines. The introduction describes the transmission system in the Czech Republic. Furthermore, the work deals with the theoretical analysis Joule´s losses, leakage current losses and corona losses. Here is described the issue of technical losses depending on the load and temperature. Solution to the area is applied to the use and operation of available software called ,,Ztráty na vedení PS" and ,,Predikce ztrát na vedení PS". Following was created methodical materials with practical calculations in Microsoft Excel with name ,,Optimalizace provozu vedení PS", which serves as preparation for new software. This software will be able to create polynomials and graphical outputs to determine the technical losses based on the transmitted power in the temperature range of measured values. The methodology of software in the Excel program was tested on the current database selected measurement data, then analysis of polynomials and graphical outputs were performed on selected lines transmission system. The diploma work describes the possibilities of using the future software with the working title ,,Optimalizace provozu vedení PS" in practice.
