Innovative design and reliability
At the heart of SVC is Merus™ thyristor valve, used in TCRs and TSCs for dynamic control of reactive power. Merus™ thyristor valve was developed to meet the highest requirements for compactness, performance and reliability in harsh industrial environments. Thanks to the state-of-the-art composite construction, the valve is compact enough to be installed even into a standard sea freight container, enabling relocatable SVC designs.
Modular design
The SVC system can be built for all medium voltage levels starting from 3.3 kV all the way up to 38.5 kV. Power output ranges from 4 MVAr to 250 MVAr. The devices can be connected in parallel for a higher total output and added redundancy. Each SVC system is tailor-made to fit the network fault level and load parameters.
Efficiency with proven control algorithms
Open- and closed-loop control strategies permit effective flicker mitigation, reactive power control, power factor control and harmonic mitigation. The thyristor valves in the SVC are equipped with Merus™ Control & Protection System that utilizes proven control algorithms.
