In-Depth Information
In transmission networks,
R
is small relative to
X
, and the voltage profile is
determined mainly by reactive power flows. Wind farms are often connected at
distribution voltage level. As we saw above,
R
and
X
may be comparable at these
voltages. Hence real power will then be more influential in determining the voltage
at the wind farm terminals than reactive power. The resulting
voltage rise
problem,
and possible solutions, will be considered in Chapter 4.
