Problems solved by technology

[0004] In actual operation, many power stations have also carried out prototype hydrological tests on the outflow flow to further correct the outflow flow deviation, but the actual results still do not eliminate the phenomenon of cascade water mismatch

Abstract

The invention relates to the technical field of optimal dispatching of reservoirs, in particular to an automatic correction system for inflow flow of cascaded reservoirs. It includes a historical data module, an interval control value analysis module, a data server, a real-time water module, and a correction module. The historical data module is used to store through the data server according to the water information entered into the intervals of each power station in cascade reservoirs over the years; the interval The control value analysis module is used to retrieve the information in the data server and analyze and calculate the control value; the water real-time module is used to calculate the water information of each power station interval according to the input of the cascade reservoir on the same day and store it through the data server; The correction module is used to correct the inbound flow. The automatic correction system for the inflow flow of cascade reservoirs of the present invention can effectively correct the inflow flow of the reservoir, and has the effect of automatic correction and reduces manual operations.

Description

technical field [0001] The invention relates to the technical field of optimal dispatching of reservoirs, in particular to an automatic correction system for inflow flow of cascaded reservoirs. Background technique [0002] The water balance equation is used to calculate inversely. According to this calculation method, it must be assumed that the flow velocity in the reservoir tends to zero, and the reservoir surface also tends to be horizontal. Taking the outflow flow and the change of storage capacity within a period of time as the known conditions, it can be deduced The average value of inbound traffic over a period of time. Theoretically, in cascade reservoirs connected in series, the inflow flow of the downstream power station is composed of the outflow flow of the upstream power station and the production flow of the basin area between the two dams. However, practice has proved that using the water balance equation to calculate the inbound flow inversely will cause th...
