Abstract: A method is provided of controlling a doubly fed induction generator- (DFIG) wind turbine converter system if a sub-synchronous resonance event acts on the wind turbine. According to the method a sub-synchronous resonance event is detected. Thereupon, a switch from a non- SSR-control mode to a SSR-control mode is performed. At least one of the following activities is performed in the SSR-control mode, namely: (i) freezing rotor AC voltages in magnitude and phase, (ii) altering at least one rotor-current-controller gain (iii) altering at least one rotor-current-controller time constant, to dampen the effect of the SSR-event on the wind turbine.

Abstract: A method is provided of protecting a wind turbine with a doubly-fed induction generator (DFIG) against a sub-synchronous resonance (SSR) event acting on the wind turbine. A plurality of power-output values or current-output values is measured over a given period of time that corresponds to a measurement cycle. It is determined whether power-output values or current-output-values measured in the at-least-one measurement cycle are indicative of an SSR-event critical for further operation of the wind turbine. The wind turbine is shut down if the measured power-output values or current-output values are indeed indicative of an SSR- event critical for operation of the wind turbine.

Abstract: A power plant control system for a first renewable energy power plant comprising one or more renewable energy generators. The power plant control system comprises receiving means for receiving a power delivery demand from a transmission grid operator; control means configured to control the one or more renewable energy generators of the first renewable energy power plant so as to supply power that targets the received power delivery demand; and communication means configured to transmit a request to one or more further renewable energy power plant control systems to request operation of one or more power compensation units associated with respective ones of the further renewable energy power plants. The embodiments of the invention are beneficial in that the power plant control system of the first renewable energy power plant has the functionality to manage the power delivery across multiple power plants, and therefore acts as an energy management system, able to active assets of other power plants so as to react quickly to any grid instabilities that may be detected. This provides a robust response to grid instabilities. The invention has particular utility to wind power plants, but also applies to other types of renewable energy power plants, for example photo-voltaic power plants, hydro-electric power plants and the like.

According to the method a sub-synchronous resonance event is detected. Thereupon, a switch from a non-SSR-current/voltage control mode to a SSR-control mode is performed. At least one of the following activities is performed in the SSR-control mode, namely: (i) freezing rotor AC voltages in magnitude and phase, (ii) altering at least one rotor-current-controller gain (iii) altering at least one rotor-current-controller time constant, to dampen the effect of the SSR-event on the wind turbine.
