Short example sentences

DC filters are required only for HVDC transmission systems involving overhead lines. (12 words)

China Southern Power Grid started a three terminals VSC HVDC pilot project in 2011. (14 words)

Capacitor-commutated converters (CCC) Line-commutated converters have some limitations in their use for HVDC systems. (16 words)

Longer example sentences

Because of this, many mercury-arc HVDC systems were built with bypass switchgear across each six-pulse bridge so that the HVDC scheme could be operated in six-pulse mode for short periods of maintenance. (35 words)

Above a certain break-even distance (about 50 km for submarine cables, and perhaps 600–800 km for overhead cables), the lower cost of the HVDC electrical conductors outweighs the cost of the electronics. (34 words)

HVDC improves on system controllability, with at least one HVDC link embedded in an AC grid—in the deregulated environment, the controllability feature is particularly useful where control of energy trading is needed. (33 words)

Example sentences (20)

Hitachi Energy pioneered commercial HVDC technology almost 70 years ago and has delivered more than half of the world’s HVDC projects.

Advantages of HVDC over AC transmission A long distance point to point HVDC transmission scheme generally has lower overall investment cost and lower losses than an equivalent AC transmission scheme.

Because of this, many mercury-arc HVDC systems were built with bypass switchgear across each six-pulse bridge so that the HVDC scheme could be operated in six-pulse mode for short periods of maintenance.

Early HVDC systems used electromechanical conversion (the Thury system) but all HVDC systems built since the 1940s have used electronic (static) converters.

HVDC improves on system controllability, with at least one HVDC link embedded in an AC grid—in the deregulated environment, the controllability feature is particularly useful where control of energy trading is needed.

HVDC overhead lines for onshore wind integration projects and HVDC cables for offshore projects have been proposed in North America and Europe for both technical and economic reasons.

The HVDC converter stations are expected to be in-service by the end of 2025 to support final testing and commissioning of the SunZia Wind facilities in 2026.

The fact that long distance HVDC cable transmission has already proven feasible is a point working in Sun Cable’s favour.

Above a certain break-even distance (about 50 km for submarine cables, and perhaps 600–800 km for overhead cables), the lower cost of the HVDC electrical conductors outweighs the cost of the electronics.

An additional advantage of the existence of HVDC links, therefore, is potential increased stability in the transmission grid.

An attempt to address these limitations is the Capacitor-Commutated Converter (CCC) which has been used in a small number of HVDC systems.

An example is the 2,000 MW Quebec - New England Transmission system opened in 1992, which is currently the largest multi-terminal HVDC system in the world.

As a result, harmonic filters are nearly always required at the AC terminals of such converters, and in HVDC transmission schemes using overhead lines, may also be required on the DC side.

A voltage sourced converter can therefore feed power to an AC network consisting only of passive loads, something which is impossible with LCC HVDC.

Bipolar HVDC lines at which each pole is operated with the same voltage toward ground are also balanced lines.

Capacitor-commutated converters (CCC) Line-commutated converters have some limitations in their use for HVDC systems.

China Southern Power Grid started a three terminals VSC HVDC pilot project in 2011.

DC filters are required only for HVDC transmission systems involving overhead lines.

Due to the space charge formed around the conductors, an HVDC system may have about half the loss per unit length of a high voltage AC system carrying the same amount of power.

Electronic converters for HVDC are divided into two main categories: * Line-commutated converters (LCC) * Voltage-sourced converters, or current-source converters.
