Zusammenfassung:A method for estimating a measurement error for expansion distance of a rotor in a turbine control system is provided to reduce an error and thud to improve reliability of measured data by calculating and using an optimal control constant. A method for estimating a measurement error for expansion distance of a rotor in a turbine control system equipped with first and second distance measurement sensors comprises the steps of: receiving characteristic data on the distance measurement sensors from a user; applying the data to a genetic algorithm and calculating a control constant; calculating a distance between the sensors and a runner using voltage values outputted from the sensors and the control constant; and calculating a distance measurement error and outputting the calculated error to a screen.
