Abstract
The application discloses a kind of water turbine guide vane and paddle's coordination method, system, device and medium, its method includes: obtaining the coordination graph of guide vane and paddle relationship, and carrying out scatter point extraction on each water head coordination curve;The extracted scatter point is fitted multiple times to obtain the fitting polynomial of each water head coordination curve;Current water head measurement value is obtained, and its upper and lower adjacent water head coordination curve is determined on coordination graph;Each guide vane opening of current water head measurement value is brought into the fitting polynomial corresponding to upper and lower adjacent water head coordination curve to calculate its paddle opening;paddle opening coordination target value is calculated by interpolation according to the calculation result of paddle opening;The data amount stored by the application is smaller, the calculation amount is small and the calculation precision is high.
