POWER GENERATING MACHINE LOAD CONTROL BASED ON CONSUMED FATIGUE LIFE TIME AND REAL-TIME OF OPERATION OF A STRUCTURAL COMPONENT

摘要

It is described a method for controlling the operation of a power generating machine (100) comprising a structural component (114, 120, 122), which during an operation of the power generating machine is exposed to a mechanical load. The method comprises (a) determining a consumed fatigue life time (254c) of the structural component, (b) determining a real-time of operation (256b) of the structural component, (c) comparing the determined consumed fatigue life time with the determined real-time of operation and (d) controlling the operation of the power generating machine in such a manner that the mechanical load acting on the structural component depends on a result of comparing the determined consumed fatigue life time with the determined real-time of operation. It is further described a machine load control system (150, 250), the power generating machine and a computer program, which are all adapted for carrying out and/or for controlling the above described operation control method.
