Braking system for wind turbines
In HVDC LCC (back to back / point to point), the converter stations are polluted with numerous harmonic distortions which must then be filtered: alternating current – AC and direct current – DC filter.
When the station is powered on HVDC VSC , the pre-insertion resistor limits the charging current of the capacitors and the cable. When the station stops, the DC cable remains charged (High capacity), the energy must be discharged into a resistor (cable discharge).
When VSC is connected to wind farms for example, if the AC grid is faulty and cannot receive power, the wind turbines must be braked using a DC chopper resistor .
