Variable shunt reactor for SINCRO.GRID

03.12.2019

The two transmission system operators (TSOs) and TSCNET shareholders ELES from Slovenia and HOPS from Croatia are cooperating in SINCRO.GRID. This cross-border smart grid initiative is coordinated by ELES and comprises in addition to the TSOs also two distribution system operators (DSOs) from both countries. The objective of the European Project of Common Interest (PCI) is to optimise the efficiency of the respective national transmission systems by means of advanced technologies and innovative data processing methods.

Since the substantial allocation of EU funding to SINCRO.GRID under the Connecting Europe Facility (CEF) programme in 2017, the project has made significant progress. A vital component of SINCRO.GRID is optimising and installing compensation devices for reactive power control, e.g. variable shunt reactors, which are used in high-voltage transmission systems for voltage stabilisation during load variations. Now the ELES substation in Divača in south-eastern Slovenia has been equipped with such a technically advanced device manufactured by Siemens in Austria. The assembly work is in full swing and is expected to be completed by 12 December. Preparatory work for commissioning will then commence immediately.

Another major component of SINCRO.GRID is a dynamic thermal rating system for power grid operating limits. The aim is to evaluate marginal capacities of transmission system components considering weather influences and thus to improve operational safety and utilisation of overhead lines and transformers. In addition to hard- and software in control centres, atmospheric measuring devices, which are installed directly at the pylons, are also part of the system. Corresponding tests of innovative weather stations are underway. Last week, the substructure for the weather station on the Kleče-Divača overhead line was field tested.
