Abstract:
|
Voltage source converter (VSC) based high voltage
dc (HVDC) transmission is an attractive technique for large
offshore wind power plants, especially when long cable
transmission is required for connection to the onshore grid. New
multi-MW wind turbines are likely to be equipped with full scale
converters to meet the stringent grid code requirements. In such
a scenario, the offshore grid is terminated to the power electronic
converters on all the ends.
This paper presents a control scheme for the synchronization
and control of the grid side converters (GSC) of the wind turbine
generators (WTG). Current limit control enables the GSC to
sustain the fault currents during short circuits in the offshore
wind collector system grid. However, power transmission is
affected, and the fault has to be isolated. It can be resynchronized
after the fault has been cleared and the breaker reclosed. Healthy
WTG converters can remain connected. The scheme is
demonstrated through PSCAD/EMTDC simulation. |
