3 FAQs about [Converter station capacitor tower installation]

What is a capacitor commutated con-Verter (CCC)?

The term ‘capacitor commutated con-verter’, or CCC, is used by ABB, since series capacitors connected between the valve bridge and the converter transform-ers influence the commutation direct. This location for the commutation capacitors was chosen as being the best of three possible positions, namely:

Why should you choose a HVDC 2000 converter station?

Another benefit is that the converter stations have more flexible layouts. Fewer individual parts translate into easier and faster completion of as-sembly work. An HVDC 2000 station also requires less space, since the new components are more compact. As a result, site costs are reduced.

Does ABB test capacitor commutated converters?

In recent years, ABB has successfully carried out extensive testing of circuit con-figurations with capacitor commutated converters using a HVDC transmission simulator. Full-scale testing of the CCC is under way in ABB’s thyristor valve module circuit.
