We now summarize what we have learnt in this module :
a)
Devices like generators can be made to absorb or supply reactive power
by controlling their field voltages. Reactive power may be controlled so
as to
maintain terminal voltage of a generator constant.
b)
Transmission Lines absorb or supply reactive power depending on
loading. Cables invariably generate reactive power.
c)
Tap Changing Transformers, Static VAR generators etc are devices which
may be used to control voltages at key points in the system.
d)
Power Flow Control and increased utilization of transmission lines is
possible by series compensators. Power flow between two regions or across
long distances can be achieved using DC links.
e)
Power Electronics based variable shunt or series devices allow
fast voltage and power flow control.
