Economical dispatch control system for cascade power station

Abstract

The invention relates to an economical dispatch control system for a cascade power station. The system is characterized in that a host server, a history server and a voice workstation serve as an engineering work station, and an operator workstation, a large-screen projection and a GPS (Global Positioning System) system are connected in parallel on a main control line; and through the reverse regulation of an upper-level large capacity power station by a small capacity power station, a load difference is safely and smoothly transferred to another adjustable power station. By using the economical dispatch control system for the cascade power station provided by the invention, the flow of an upper-level power station unit can be effectively controlled through the flow of a lower-level power station; the water rate is lowered, the economic benefit of the power station is increased, the cost recovery time is effectively reduced, and thus the current low-carbon economic development trend is conformed to.

Description

Technical field [0001] The invention involves an economic dispatch control system, which especially involves the economic dispatch control system used in the stall power station in domestic hydropower stations, which belongs to the field of monitoring technology in the hydropower industry. Background technique [0002] At present, all the water elevator -ranges are implementing the development strategy of "river basin development, rolling development", but during the seasons of water and electricity development, there are steps for power generation plans to generate power generation.Sustainable development of a stepped power station group.In addition, any accident during the operation of each power plant will affect the power generation operation of other power stations, and it also has an unnecessary impact on the power scheduling. [0003] Because the industrialization of the domestic watershed economic scheduling control is still in the development stage, there is still a blan...

AI Technical Summary

Problems solved by technology

[0002] At present, all cascaded hydropower basins are implementing the development strategy of "watershed development, rolling development". However, in the process of hydropower development in the basin, there are cascade hydropower stations that rely on experience to make power generation plans, which not only wastes priority water resources, but also is not conducive to real development. Sustainable Development of a Cascade Power Station Group

In addition, any accident during the operation of each power station will affect the power generation and operation of other power stations, which will also cause unnecessary impact on power dispatching

[0003] Since the industrialization of domestic river basin economic dispatching control is still in the development stage, there are still gaps in some specific control modes. When dealing with the working condition that the maximum power generation flow of the lower-level power station is smalle...
