Abstract

The invention discloses a prediction method and device for generating capacity of a tubular turbine. The method comprises the steps: obtaining prediction parameters used for predicting the generatingcapacity of the through-flow turbine, wherein the prediction parameters comprise the water inlet amount H of a water storage device connected with the through-flow turbine, the water outlet amount F of the water storage device, the turbine efficiency E1, the generator efficiency E2 and the gravity constant g; based on a first preset formula, determining a plurality of first predicted generating capacities of the tubular turbine within a preset time according to the prediction parameters; according to the actual historical generating capacity curve of the tubular turbine, repairing each first predicted generating capacity, and obtaining a corresponding target prediction generating capacity. According to the method, the technical problems that the prediction difficulty of the generating capacity of the water turbine is increased and the accuracy of the predicted generating capacity is relatively low due to many parameters involved in the generation prediction of the water turbine and strong randomness of the parameters when the generating capacity of the through-flow water turbine is predicted in the prior art are solved.

Description

technical field [0001] The present application relates to the technical field of hydroelectric power generation, in particular to a method and device for predicting the power generation of a tubular water turbine. Background technique [0002] With the development of electric power technology, my country's power generation technology has made remarkable achievements. According to different power generation types and power generation scales, the corresponding generator sets are studied to achieve reasonable power generation and ensure stable power supply. [0003] Due to the advantages of small size, low construction cost, short construction period and quick return, the tubular turbine has been widely used in some small hydropower stations. The power generation obtained by predicting the power generation of the tubular turbine can not only arrange the power generation of the power station installed with the tubular turbine, but also allow the power station to participate in ...
