Abstract: The invention relates to a power plant controller for controlling wind turbine generators. More particularly, the invention relates to a method for compensating data obtained from measurements at a connection point to the grid in case of a communication failure where communication of such data is lost or becomes unreliable. The measured data are used in the power plant controller for determining setpoints for controlling the wind turbine generators' production of active and reactive power. In response to detection of a communication fault a new setpoint is determined independently of new measured grid data by reconfiguring parts of the power plant controller.

Abstract: The invention relates to a control system for a wind turbine generator, WTG. The control system defines reactive limits for a reactive power reference for the WTG. The reactive limits are defined as a function of a physical parameter, e.g. the output voltage of the WTG. In case the reactive power reference exceeds the predefined limits, the reactive power reference is limited. By limiting the reactive power reference output voltages which exceed certain output voltage limits may be avoided and, thereby, a disconnection of the WTG from the grid may be avoided.

Abstract: The present invention relates to a method for controlling a wind power plant connected to an electrical grid, the wind power plant comprising at least one wind turbine generator and a power plant controller, the power plant controller comprising a signal controller for controlling an electrical parameter with a gain (Kgs), the method comprising, measuring at least one electrical parameter in the electrical grid, determining an internal signal value at least partially based on the at least one electrical parameter, comparing the internal signal value with a saturation value, and if the internal signal value exceed the saturation value, increasing the gain (Kgs) of the signal controller to a first gain value, in order to decrease a rise time for a slope for the electrical-parameter in the electrical grid. The invention also relates to a power plant controller arranged to decrease a rise time for a voltage slope for a voltage parameter in the electrical grid.
