Abstract: A method for use in controlling a wind turbine generator (1) of a wind power plant based on a condition of a power converter or a component forming part of a power converter in the wind power plant. The method comprises determining the initial condition of the power converter or a component forming part of a power converter and determining the evolution of the condition from the initial condition based on notional power reference values of the wind turbine generator (1). The method further comprises comparing the evolution of the condition to a predetermined threshold and determining, from the comparison, a time period by which the condition of the power converter or a component forming part of a power converter will substantially equal the predetermined threshold.

Abstract: METHOD OF CONTROLLING A WIND TURBINE GENERATOR A method of controlling a wind turbine generator (1) comprising a power converter (22) and at least one circuit breaker (25, 41). The method comprises determining a condition of the circuit breaker (25, 41) and modifying one or more operational parameters of the power converter (22) in accordance with the condition of the circuit breaker (25, 41). In particular, the invention proposes that the converter (22) is derated if one or more of the circuit breakers (25, 41) is close to violating a protection characteristic, thereby avoiding tripping of the circuit breaker (25, 41) and the associated lost production.

Abstract: A method for use in controlling a wind turbine generator (1) based on a condition of a power converter or a component forming part of a power converter in the wind turbine generator (1). The method comprises determining a condition of the power converter or the component forming part of a power converter, then comparing the condition to a predetermined threshold and modifying an operational parameter of the wind turbine generator (1) if the condition substantially equals or exceeds the predetermined threshold. In particular, the invention proposes the wind turbine generator (1) is derated if the condition of the power converter or the component forming part of a power converter substantially equals or exceeds the predetermined threshold.
