The present invention relates to a system adapted to reduce the load of a wind turbine in situations with high yaw error or by gust ride, which system has access to at least t some operational parameters. The object is to reduce the maximal load of a wind turbine in situations where wind gust hits the wind turbine. The system can monitor at least a combination of these parameters, which system by a defined combination of at least some of actual parameters performs a pitch or speed regulation in order to bring the wind turbine into a safe mode of operation and reduce the load of the wind turbine. Hereby can be achieved that the system can monitor some of existing parameters for a wind turbine in operation and through these parameters it is possible with this system to perform an analysis of critical combinations of parameter values. In that way the system can react if a critical load exists because there is a critical combination of parameters and change the pitch of the blades towards the feathered position or by speed reduction.
