Abstract:
|
Large and distant offshore wind power plants can
be efficiently connected to the onshore power grid network using
VSC-HVDC (Voltage Source Converter based HVDC)
transmission. Chopper controlled resistors can be used to limit
the DC line over-voltage when there is a fault on the onshore AC
grid and power transfer to the grid is obstructed. Considering
the development of full scale converter based wind turbine
generators (WTG), use of unit rated chopper controlled resistors
for each of the full scale AC-DC-AC converter system of the
individual turbines has been proposed in place of the one on the
HVDC line side. Both the cases have been simulated and their
performances are found to be similar. Thus, it justifies that the
chopper resistors in the full scale converters are sufficient to
handle the low voltage fault ride through (LVRT) conditions. |
