ADAPTIVE MODEL-BASED METHOD TO QUANTIFY DEGRADATION OF A POWER GENERATION SYSTEM
A system includes a power generation system and a controller that controls the power generation system. The controller includes a processor that generates a model of the power generation system that estimates a value for a first parameter of the power generation system. The processor also receives a measured value of the first parameter. The processor further adjusts a correction factor of the model such that the estimated value of the first parameter output by the model is approximately equal to the measured value of the first parameter. The processor also generates a transfer function that represents the correction factor as a function of a second parameter of the power generation system. The processor further displays the transfer function along with one or more previously generated transfer functions to quantify degradation of the power generation system.
COMPONENT MOUNTING SYSTEM AND ERROR STOPPAGE DIAGNOSIS METHOD FOR COMPONENT MOUNTING DEVICE
In a component mounting system, recovery processing is repeated until a recovery count number Nr is larger than or equal to a defined count number Nth in a case where a pickup defect of a component occurs, an elapsed time is measured from error stoppage of a component mounting machine to canceling of the error stoppage in which the component mounting machine is error-stopped when the recovery count number Nr is larger than or equal to the defined count number Nth, the defined count number Nth is increased within a range in which the defined count number does not exceed the upper limit value Nmax in a case where the elapsed time is shorter than a defined time Tth, and the defined count number Nth returns to an initial value in a case where the elapsed time is longer than or equal to the defined time Tth.
