Abstract: Techniques for enabling the configuration of a voting block for use in a process control system of a process plant are described. According to certain aspects, the voting block may have a voting scheme that dictates an output based on a set of inputs, where the voting block may be configured parametrically using various control selections that direct the behavior of the voting scheme. In particular, a bypass degrade selection may be specified for one or more inputs that controls whether a “bypass” input degrades the voting scheme, a status degrade selection may be specified for one or more inputs that controls whether a “bad” input degrades the voting scheme, and a trip enable selection may be specified that controls whether a trip occurs automatically under certain conditions. The control selections enable the voting blocks to be configured to conform with various specifications and other requirements.

Abstract: A method for operating a wind turbine wherein a parameter for a wind hitting the wind turbine is determined from present values for the generator speed and/or the wind speed at each point in time (t). A temporal change variable is formed for the parameter at each point in time (t). For the temporal change variables, which occurred in a past time interval, the third and/or fourth statistical moment is calculated for a distribution of the temporal change values in the time interval. If at least one of the statistical moments exceeds a predetermined value, then a detection signal is set for an extreme gust, which triggers one or both of the steps: increasing a setpoint value for the blade pitch angle starting from an actual value thereof, and reducing a setpoint value for the generator speed starting from an actual value thereof.
