A reservoir hydropower station optimal power generation control system in flood seasons

Abstract

The invention discloses a reservoir hydropower station optimal power generation control system in flood seasons, which comprises a rainfall monitoring unit, a water level monitoring module, a data prediction unit, a database, a controller, a display module, a storage module, a data input module, a water level control module, a power generation unit and a water dumping unit. By setting a designatedwater level information, the present invention labels the water level information at this time as a water storage level Sx; when the water level information is Sx, the water storage of the reservoiris lower than the normal level, and the water storage operation should be carried out at the time. At the same time, the water level information corresponding to the maximum safe storage capacity of the reservoir is marked as Sz. By presetting a water level information buffer value A, Sz-A is marked as Sc; a specified water level information range is set and the water level information range is marked as Sx-Sc; when the water level information is located in the range of Sx-Sc, the water storage capacity of the reservoir reaches the normal level; when the water level information exceeds Sc, thewater dumping measures shall be started at this time.

Description

technical field [0001] The invention belongs to the field of hydroelectric power generation, and relates to a flood season power generation technology of a reservoir hydropower station, in particular to a flood season optimized power generation control system for a reservoir hydropower station. Background technique [0002] Hydropower generation uses rivers, lakes, etc. to flow water with potential energy from high places to low places, convert the potential energy contained in it into kinetic energy of water turbines, and then use water turbines as the driving force to drive generators to generate electricity. Use water power to drive the hydraulic machinery to turn, and convert the water energy into mechanical energy. If another machine is connected to the water turbine and rotates with the water turbine, electricity can be generated. At this time, the mechanical energy is converted into electrical energy. In a sense, hydropower is a process in which the potential energy o...

Problems solved by technology

[0004] At present, hydropower is used in many relatively large reservoirs, but the application of hydropower is the process of converting the failure of water into the mechanical energy of the water wheel. In this process, the step of water storage is required. , but when the flood season comes, it is necessary to take measures to abandon water in time; however, blind water abandonment will cause a waste of hydraulic power, and failure to abandon water in time may cause some safety hazards due to overloaded water storage in the reservoir; therefore, there is a lack of an accurate monitoring The water level system can make timely and accurate decisions on water abandonment and water storage; in order to realize this vision, a solution is now provided
