hello,
that anyone have the cost of the dc breaker that will be used in multiterminal hvdc system ?
thank's
The problem is not so much a problem of cost but more of feasibility
ABB announced in November 2012 that they achieved an HVDC breaker
called hybrid HVDC breaker but this is all pretty new
Callavik, M., A. Blomberg, J. Häfner, and B. Jacobson. 2012. "The Hybrid HVDC Breaker-An innovation breakthrough enabling reliable HVDC grids". ABB Grid Systems, Technical paper Nov.
thank' for the answer but i need more information about the cost of dc breaker , i need this for an economic comparison between the radial and meshed configuration of the multiterminal DC installation.
Thanks in advance
This is quite new technology, and I can be wrong but I don't think it has ever been sold and therefore no price exist.
When new technologies are introduced, the price won't reflect the actual cost of the technologies, but rather what people are willing to pay. Its market price should be similar to having an equivalent installation of all AC system.
the cost of dccb generally is consider as an estimation or pourcentage of the conversion station
Absolutely, DCCBs have not yet been delivered commercially and as such there is no cost data available. An estimate is therefore required based on knowledge of the proposed design solutions
