In previous HVDC projects, be it back to b … In previous HVDC projects, be it back to back or DC Transmission
lines, the converters and inverters were constructed with vacuum tube
technology known as mercury arc valves. These were prone to re-strikes,
which deteriorated the transient performance of the facilities. The
Nelson River project (recent milestone for 900 km HVDC transmission
system) retrofitted thyristors to half of their bridges, which enabled
the technology to be proven and pave the road for the Eel River Project
shortly after. A converter has the Alternating Current connection at
its input and the Direct current at its output. An inverter is the
opposite. A converter / inverter constitutes a DC Link. If the
distance is long, we call it a DC Transmission Line. If the distance is
short like at Eel River (some 30' of 2000 Ampere bus), then it is a
back-to-back HVDC station. ), then it is a
back-to-back HVDC station.

The major technical obstacle was to obtain … The major technical obstacle was to obtain acceptable transient
performance during disturbances. Having enough voltage support was also
the challenge, and required three rotary synchronous converters and
nearby 112 MVA Dalhousie Plant to maintain voltage and give the
electronic station some inertia. Control systems included a governing
function and a stabilizing function, both based on the judiciously
weighted frequency difference of both systems. hted frequency difference of both systems.

organize a celebration event in conjunction with Engineering Week, which
is held annually in February. We would propose an event be held at the
University of New Brunswick in Fredericton, along with representatives
from the IEEE, and IEEE NB Section. In addition, we would invite key
stakeholders and the media to attend. After the plaque is received, it
would be displayed in the main lobby of our Dalhousie Generating
Station, where it would be visible to employees and visitors for viewing. ble to employees and visitors for viewing.
