Compensation devices for reactive power control
Compensation devices for reactive power control are a modern means of regulating voltage profiles in the electricity grid. They allow us to ensure a higher reliability of operation of the entire electricity transmission grid and reduce the risk of failure of any basic building blocks of the transmission grid (tramission lines, transformers, etc.), which are vital for the undisturbed operation of both large industrial consumers as well as households. The devices reduce the probability of grid outages and enable quicker recovery of the grid in the event of any faults.
To ensure effective voltage control, an optimal combination of various high-tech advanced devices for the compensation of reactive power and voltage regulation will be incorporated in the Slovenian and Croatian transmission systems. In Slovenia, the SINCRO.GRID - Phase 1 project comprises, among others, the installation of a stationary compensation device with a SVC/STATCOM technology of +/- 150 Mvar at the Beričevo substation, the installation of variable shunt reactor of -150 Mvar and the installation of a capacitor of +100 Mvar at the Divača substation. In Croatia, three devices will be installed – variable shunt reactor of -100 Mvar at the Mraclin substation, variable shunt reactor of -200 Mvar at the Melina substation and stationary compensation device with a SVC technology of - 250 Mvar at the Konjsko substation.
