摘要： According to the disclosure, a position of a main control valve and a position of an auxiliary control valve are adjusted. In particular, a position of the auxiliary control valve is adjusted by determining whether a change in the position of the main control valve is in a preset deadband range, thereby preventing a periodic water level fluctuation of a steam generator.

摘要： Provided are a method and system for improving control of a steam generator level for preventing oscillation of the steam generator level in a nuclear power plant. In order to prevent oscillation of a steam generator level and resultant shutdown of a nuclear reactor, which may be caused when a high-level priority control function is frequently and repeatedly turned on/off as the steam generator level is excessively increased, by improving a feedwater control system in the nuclear power plant, a proportional integral control value may be controlled to be reduced, and thus, output while a certain condition is met after a high-level priority mode is deactivated or a signal instructing to enter the high-level priority control mode may be controlled not to be output.

摘要： Provided is an apparatus for controlling a gain according to a water level change rate of a steam generator in nuclear power plants. The apparatus includes a water level variance detector detecting a water level variance of the steam generator, a change rate calculator calculating a water level change rate with respect to the detected water level variance, a compensation value calculator calculating a compensation gain value corresponding to the calculated water level change rate, a reactor power sensor sensing whether or not reactor power corresponds to certain power or less, and a gain compensation controller, when the reactor power corresponds to the certain power or less, outputting a control gain value obtained by combining a general gain value provided to control a proportional-integral (PI) controller with the compensation gain value to the PI controller
