Embodiment Construction

[0024] The entire process of intelligent optimal scheduling of the cascade hydropower centralized control station automation system is as follows:

[0025] 1) Use the cascade hydropower centralized control station automation system to configure and store the parameter information of each cascade hydropower station, including the upper limit of the water level, the lower limit of the water level, the normal water storage level, the design water head, the adjustment storage capacity, the water flow time lag of the upstream and downstream hydropower stations, the unit capacity, The rated flow rate of the unit and the non-operating area of ​​the unit;

[0026] 2) Use the cascade hydropower centralized control station automation system to collect real-time data of each hydropower station, including unit active power, water level in front of the dam, tail water level, water head, flow, etc.;

[0027] 3) Use the cascade hydropower centralized control station automation system to obta...

Abstract

Discloses is an intelligent optimization scheduling method of a cascade hydroelectric centralized control station automation system. Artificial estimation and scheduling for a cascade hydroelectric station are modified into intelligent optimization scheduling of the cascade hydroelectric centralized control station automation system, and factors like basic water conditions of a drainage basin and electrical safety operation are taken into comprehensive consideration through intelligent optimization scheduling software; based on the flow equilibrium principle in the whole drainage basin and according to cascade load curves or real-time active target values given in a cascading manner through high scheduling, a machine set controlled by involvement of a cascade hydroelectric station is automatically allocated with the active load through fast cascade simulation triggered through events and a quantum evolutionary scheduling algorithm, an economic scheduling scheme is put forward at present and within follow-up period of time, and automatic generation control is performed on all levels of the hydroelectric stations.

Description

technical field [0001] The invention relates to an intelligent optimization scheduling method for an automation system of a cascade hydropower centralized control station. Background technique [0002] As a renewable clean energy, hydropower occupies an extremely important position in the history of my country's energy development and supports the sustainable development of the economy and society. At present, in the development and utilization of river basins and cascade hydropower, although the coordinated operation of cascade hydropower stations is considered in the design and planning, in the actual operation management process, due to the lack of effective and automatic comprehensive coordination and optimal dispatch methods, it often remains in the At the stage of manual estimation and manual dispatch relying on historical data and dispatcher experience, the water energy utilization efficiency needs to be improved, and economic dispatch and automatic power generation c...
