Abstract

The paper investigates the impact of a static VAR compensator on voltage circumstances and reactive power flows in a Croatian power transmission grid. The research has been conducted between Melina SS–reversible Velebit HEPP–Konjsko SS under low- and high-load conditions of the system. During the research, the possibility of higher transfer capability of the existing HV overhead lines was identified through the reactive power flow control on the grid. Today's degree of industrialization and the living standards require exceptionally high quantities of electric energy, which is a great problem for the existing transmission systems having insufficient capacity to meet the increasing needs and demands of customers. The key parameters for solving the problems are the line transfer capability, voltage stability and reactive power compensation, which could be improved in terms of their high capabilities and better control by means of SVC devices.

Keywords
