Slovenian transmission system is occasionally faced with high voltage deviations from normal security limits. The objective of the thesis is on one hand to develop a tool which enables tracking of voltage management performance indicator and on the other hand indication of the unexecuted measures which have led to the voltage deviations.
In the first part of the thesis, the requirements of Slovenian national grid code (SONPO) regarding the voltage levels are discussed. Furthermore the reactive power influence on voltages in the transmission system are discussed and means for successful voltage management exposed. For the simulations of voltage influencing factors, NEPLAN power system simulation software has been used, which is also briefly described in the thesis.
The second part is dedicated to the performance indicator tool development. First the possibility of reducing the range of the input data in order to increase speed of procedures execution is analyzed. Finally a detailed description of the tool functionalities are presented.
