Abstract
A method of transmitting reactive power between at least one wind turbine and a power system through a transformer connected between the at least one wind turbine and the power system, the wind turbine including a power converter. The method includes a second step of connecting at least one passive device to the transformer and reducing or increasing a reactive power of the power converter of an amount corresponding to the reactive contribution from the passive device.
Claims4
A method of transmitting reactive power between at least one wind turbine and a power system through a transformer connected between the at least one wind turbine and the power system, the at least one wind turbine including a power converter, the method including:
- a first step of ramping a reactive power from a maximum reactive import towards a maximum reactive export up to when a first threshold is reached,
- a second step of connecting at least one passive device to the transformer and reducing a reactive powder of the power converter of an amount corresponding to the reactive contribution from the at least one passive device,
- a third step of ramping the reactive power towards the maximum reactive export up to when the maximum reactive export is reached.
