Wind power plant, and a method for increasing the reactive power capability of a wind power plant

A wind power plant, comprising:

• a plurality of wind turbine generators;
• and
• a power plant controller configured to:
• receive a reactive power requirement associated with an electrical grid;
• determine an active power generated by the wind power plant;
• determine, based on the active power generated by the wind power plant, whether the reactive power requirement is satisfied by the wind power plant;
• determine, based on an electrical characterization of the wind power plant, a maximum active power amount at which the reactive power requirement is satisfied;
• determine a curtailment amount for the wind power plant based on the maximum active power amount;
• and
• responsive to detecting a grid event:
• control, when the reactive power requirement is not satisfied, the wind power plant to curtail the active power generated by the wind power plant by the curtailment amount.

A computer program product directly loadable into an internal memory of at least one digital computer provided in a wind power plant, comprising software code portions which, when executed on the at least one computer, perform an operation for increasing the reactive power capability of a wind power plant, the operation comprising:

• receiving a reactive power requirement associated with an electrical grid;
• determining an active power generated by the wind power plant;
• determining, based on the active power generated by the wind power plant, whether the reactive power requirement is satisfied by the wind power plant;
• determining, based on an electrical characterization of the wind power plant, a maximum active power amount at which the reactive power requirement is satisfied;
• determining a curtailment amount for the wind power plant based on the maximum active power amount;
• and
• responsive to detecting a grid event:
• communicating, when the reactive power requirement is not satisfied, one or more active power set points to one or more wind turbine generators of the wind power plant to curtail the active power generated by the wind power plant by the curtailment amount.
