Užití databází měřených hodnot k analýze provozu vedení přenosové soustavy

Abstract

This thesis deals with the analysis technical losses of six particular transmission system lines of the Czech republic applying the database of measured values. The theoretical part focuses on timeline (past, presence and future) of the Czech transmission system as well as on the analysis of the VVN line and ZVN line technical losses, including Joule´s losses and π matching network. The analysis uses measured values from the databases which have been adjusted before applying. The practical part is divided into two parts. First part deals with technical losses depending on transmitted power only using software „Ztráty na vedení“ and software MS Excel. This way assumes the flow state of particular line. In the second part there is used the software „Optimalizace provozu vedení PS“ to create the technical losses model state depending on the amount of transmitted power of the particular line and surrounding temperature. In the conclusion, there are the summary and the evaluation of the measured data based on which final results are made.
