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 distribution of gate opening of a cascade hydropower station. The system includes a collection terminal, database server, application server, process library, policy library, information publishing cat, and remote control system, a collection element, transmission element, simulation element, and constraint element are arranged onthe application server and are connected with the database server, process library and information publishing cat. The invention can adjust the gate in advance, at the same time, the opening degree of each gate of the preset dispatching strategy is given by using the subsection step-size mutation algorithm, In addition to real-time monitoring of reservoir water level, effectively shorten the timeof making gate opening, A good balance has been struck between flood control and flood resource utilization, In order to reduce the working intensity of the operators and accurately control the waterlevel of the reservoir, the calculation process is simple and quick, and the follow-up effect of cascade flood control storage capacity under different flood discharge is taken into account, so as tomeet the needs of the actual operation of the power station for the calculation result accuracy, safety, real-time performance and economy.

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...
