Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hydrological forecasting, and in particular to a state synchronization method of a water conservancy model. BACKGROUND

[0002] Real-time operation forecasting is an important part of the construction of a water conservancy intelligent business application system, and real-time water conservancy calculation is an effective implementation technique for the function, and necessary conditions thereof include a water conservancy model, initial conditions and boundary conditions. Real-time water conservancy calculation requires the water conservancy model to provide peak values and processes of key sections of a basin in a short time, thereby providing guidance for engineering operation and dispatching.

[0003] In actual application, there is a problem of initial value of a state variable for a real-time water conservancy calculation task. The state variable refers to an intermediate process calculation variable other than model input and output during model calculation, and the initial value of the state variable is the initial condition, and the specific value of the initial condition has a significant influence on the result of flood forecasting.

[0004] Since the state variable is difficult to be directly obtained through observation means, the initial value of the state variable is mainly given by a human being at present, and there are the following two commonly used methods:

[0005] One is a preheating method, that is, a state variable value at a time before a calculation start time is given, and continuous calculation is performed from the time to a flood start time, and then real-time calculation is performed. The preheating method can eliminate the influence of the initial condition on the result through continuous calculation, and the result of the preheating method is reliable, but the continuous calculation is time-consuming, and cannot meet the timeliness requirement of real-time calculation.

[0006] The other is a direct assumption method, that is, a state variable value at the calculation start time is directly given to drive model calculation, and the method can meet the time requirement of real-time calculation, but the result is directly affected by the initial value of the state variable, and the error of the result is large.
