Hydropower station load self-adaptive dynamic adjustment method and system based on water head change

Abstract

The invention provides a hydropower station load self-adaptive dynamic adjustment method and system based on water head change. The method comprises the steps that a water turbine operation characteristic curve of a hydropower station is constructed; performing credible judgment on the water head data issued by the centralized control center and the measured water head data of the hydropower station; when both the water head data issued by the centralized control center and the measured water head data of the hydropower station are credible, determining a preliminary credible water head issued by the centralized control center and a measured preliminary credible water head according to the water head data issued by the centralized control center and the measured water head data of the hydropower station within a preset first duration; a main water head is selected, the maximum output of the main water head is determined, and then the load of the hydropower station is adjusted based on the maximum output; and updating the main water head based on a preset second duration, determining the maximum output of the updated main water head, and then carrying out self-adaptive dynamic adjustment on the load of the hydropower station. According to the technical scheme, efficient, safe and economical operation of the hydropower station under different water head conditions is achieved.
