Line impedance compensation system
First Claim
1. A power plant controller of a wind power plant comprising a plurality of wind turbine generators, the power plant controller configured to:
- receive at least one measured electrical parameter at a point of measurement located at a first location on a grid coupled with the wind power plant, wherein the point of measurement is different from a first point located at a second location on the grid,estimate a delta value of a difference of at least one electrical parameter between the first point and the point of measurement, wherein the delta value is based on an impedance between the point of measurement and the first point, and a reference value of the power plant controller, andcontrol the at least one electrical parameter based on the at least one measured electrical parameter and the delta value.

Abstract
The present invention relates to a power plant controller (23), controlling at least one electrical parameter of a wind power plant at a first point (201), the power plant controller receiving at least one measured electrical parameter at a point of measurement (204a, b), the point of measurement being different from the first point, and estimating a delta value of a difference of the at least one electrical parameter between the first point and the point of measurement, wherein estimating of the delta value is calculated based on an impedance between the point of measurement and the first point, and at least one reference value of the power plant controller, and the power plant controller controls the at least one electrical parameter on the basis of the at least one measured electrical parameter and the delta value.
