Abstract

The invention discloses a method for calculating reservoir inflow, and belongs to the field of hydrographic survey, the reservoir inflow is calculated in real time through loop iteration by adopting an inverse method based on a reservoir water balance principle, and the method comprises the following specific steps: collecting and sorting operation characteristic data of a water-turbine generator set and operation data of a reservoir; accurately calculating the power generation flow, the reservoir capacity increment and the flood discharge flow; anyalzing, calculating and sorting the guide vane water leakage amount, the regional civil life or irrigation water taking amount, the reservoir water surface evaporation amount and seepage in the unit stopping period; calculating a reservoir flow according to a water balance principle, wherein the reservoir flow is equal to power generation flow + reservoir capacity increment + flood discharge flow + guide vane water leakage during unit stop and preparation + regional civil life or irrigation water intake + reservoir water surface evaporation capacity and seepage; and carrying out back-stepping loop iterative calculation to obtain the reservoir flow. The invention is designed based on an Excel Visual Basic functional platform, serves as an auxiliary tool for reservoir economic operation analysis of field production personnel, and realizes safe and economic operation of a hydropower station.

Description

technical field [0001] The invention belongs to the field of hydrological measurement, and in particular relates to a method for calculating the inflow flow of a reservoir. Background technique [0002] Real-time inflow flow is an important indicator to guide the economic operation of reservoirs. Real-time flood scheduling and real-time flood forecasting require accurate calculation of inflow flow. In order to make full use of water resources, ensure the safety of reservoir flood control and bring into play the comprehensive benefits of the reservoir. The real-time monitoring system of Bikou water regime was upgraded in 2006. Since the system was put into operation, the smoothness rate of the system has been good, which has provided more accurate information for reservoir dispatching and played a good role in the flood control dispatching of the reservoir. However, with the extension of the commissioning time of the system, and the power generation of the Miaojiaba Power St...
