Embodiment

[0112] Such as Figure 1-3 As shown, the real-time automatic allocation method of the flood gate opening of the cascade hydropower station in this embodiment includes the following steps:

[0113] The first step is to formulate various reservoir water level control intervals, formulate reservoir water level control strategies according to flow levels and timeliness, and store them in the strategy library, and store the data of cascade flood control power generation facilities (such as unit NHQ curves, gate overflow curves) , storage capacity curve, flood gate constraints, etc.) are converted into static parameters of corresponding power stations according to different priority orders and cascade relationships, and stored in the database.

[0114] In this embodiment, the cascade hydropower stations: Dagangshan Hydropower Station, Pubugou Hydropower Station, Shenxigou Hydropower Station, Zhentouba Hydropower Station, Gongzui Hydropower Station and Tongjiezi Hydropower Station ar...

Abstract

The invention discloses a method and system for real-time automatic allocation of the flood gate opening of cascade hydropower stations. The system includes a collection terminal, a database server, an application server, a process library, a strategy library, an information release modem, and a remote control system. The application server is arranged with a collection unit and a transmission unit. , simulation element, constraint element and connect with database server, process library and information release modem. The invention can make gate adjustment actions in advance, and at the same time, adopts the segmental step size mutation algorithm to give the opening of each gate that needs to be adjusted in the preset scheduling strategy. In addition to monitoring the water level of the reservoir in real time, it can effectively shorten the time for making the gate opening. A good balance has been achieved between flood control treatment and flood resource utilization to achieve the purpose of reducing the work intensity of operators and accurately controlling the operating water level of the reservoir. Accuracy, security, real-time and economical requirements of calculation results.

Description

technical field [0001] The invention belongs to the field of flood control dispatching of cascade hydropower station groups, and in particular relates to a method and system for real-time automatic allocation of flood gate openings of cascade hydropower stations. Background technique [0002] Cascade hydropower stations are always constrained by hydraulic power and their own working conditions, and a flood control model must be established under the comprehensive constraints of cascade hydropower stations at all levels to ensure flood control safety in all aspects of the entire cascade, especially in emergency situations such as flood fighting and disaster relief. Mode is an important issue in flood control of cascade hydropower stations. With the continuous expansion of the construction scale of cascade hydropower stations, the dimensions and data volume involved in a flood are rapidly increasing geometrically. Manual means cannot fully track the changes in these data. It i...
