Compensation of reactive power to avoid its overflow into the MV system
 Jurák, Viktor ; Ptáček, Michal (referee) ; Orságová, Jaroslava (advisor)
This master thesis is focused on analysis of reactive power flow in LV and MV networks. In the first part there is a definition of reactive power and description of individual parts of electrical networks that contribute with their reactive power to distribution network. The second part is dedicated to calculation of power flow in simulation software PSS® Sincal where on numerical models of network different types of network configuration are tested and consequently its influence on reactive power flow is evaluated. A more detailed analysis is dedicated to reactive power compensation in networks with distributed generation equipped with Volt-Var regulation and its possible negative mutual influence. This thesis also includes general recommendation on the basis of network simulation analysis concerning installation of compensating systems in distribution transformer station.

Influence Of Reactive Power Compensation In Transformer Station On Voltvar Regulation Of Distributed Energy Sources
 Jurák, Viktor
This article is focused on the influence of reactive power compensation on the secondary side of the distribution transformer on the Volt-Var regulation of distributed power sources in LV networks. The paper shows the mutual effects of compensation and Volt-Var control on a simple simulation in PSS® Sincal. The first part of the paper is dedicated to the description of the simulated scheme and parameterization of individual components. In the second part the results of the simulation are summarized, the contraindications identified, and recommendations are given.
