The product description Data download

The TEBA launched TSVG series static var generator by insisting the design principle of “reliability, high efficiency, and energy-saving” based on special working condition of new energy power station. Its excellent smart chain redundancy technology, control system redundancy technology, and parallel control technology of master-slave coordination improve reliability of the product greatly.

Technical advantages

Power quality problem of the new energy power station can be accurately solved based on unique harmonic compensation and resonance inhibition function, unbalance compensation function, operation capability under frequency out of range, high-accurate module voltage-sharing technology, subsynchronous vibration inhibition technology to guarantee better and more energy production.

Advanced cooling system and container body with high IP degree (IP54) can guarantee the product operates reliably in extremely bad environment. Smart control unit of fan and unique idle operation mode can save 44% energy loss of the power station and reduce the operational cost.
