Utility
Voltage control in wind power plants
9 Nov 21
A control system for controlling the power output of a plurality of renewable energy generators, a power network connecting those generators to a Point of Interconnection (PoI) with which the power network is connected to an external power grid, and measurement means configured to measure electrical parameters associated with the Point of Interconnection, wherein the control system is configured to: operate each renewable energy generator to achieve a respective current level at a terminal of the generator that is equal to a current set point; implement, during a grid fault event, a feedback control routine in which the control system: determines a measured value of an electrical parameter at the Point of Interconnection, determines a target value of the electrical parameter; and modifies the current set point based on the measured value and the target value of the electrical parameter.

Utility
Wind turbine safety system
9 Nov 21
The present invention relates to a method, controller, wind turbine and wind farm that advantageously determines an ice throw risk zone (302) for a wind turbine (301), wherein the ice throw risk zone (302) defines an area surrounding the wind turbine (301) within which ice can be thrown from one or more blades of the wind turbine (301); determining whether the determined ice throw risk zone (302) impinges one or more exclusion zones; and if the determined ice throw risk zone (302) impinges one or more exclusion zones, determining an alteration to one or more operating parameters of the wind turbine (301) in order to alter the ice throw risk zone (302) such that the determined ice throw risk zone (302) does not impinge the one or more exclusion zones.
