System Reliability

Reliability is vital for wind power systems.  Experience has shown the frequency of failure to be attributable to the following:

Gearbox 30%
Generator 6%
Cable Collector System 22%
Control System 3%
Hydraulics 12%
Yawing System 3%
Other 8%

Obviously attention has to be given to the Cable Collector System.  The recommendations described above, particularly the “all-copper” design will contribute to high performance. Other components should also be specified with a view toward long and durable service life.  In many cases, the effect of incidents if they were to occur at a power generation facility would result in minutes or hours offline, but they can cause major delays and require extensive efforts to repair at a wind generation facility.

As Canada becomes more and more dependent on this clean and safe energy source for a significant proportion of our electrical needs, system reliability becomes increasingly more important. Choosing superior and effective materials like copper cabling and related equipment will result in the continued growth and effective performance of present wind farms as well as those planned for the future.
