Abstract

The invention discloses a joint optimization regulation system for cascade hydropower stations. The system comprises a remote centralized monitoring system, a water regulation automation system, a tele-meter reading system and a remote image monitoring system, wherein the remote centralized monitoring system and the water regulation automation system are connected after being safely isolated by a hardware firewall, thus realizing the logic isolation, message filtering and access control of the two areas; the water regulation automation system and the tele-meter reading system are connected by an RS-232 serial port; and the remote centralized monitoring system, the water regulation automation system and the tele-meter reading system are all provided with a WEB releasing sub-system which is connected with the remote image monitoring system through a router with a fireproof wall. With the adoption of the joint optimization regulation system provided by the invention, the safety of the system can be improved, the centralized unified management and scheduling can be realized, the number of management persons can be reduced, and the cascade joint scheduling benefits can be improved.

Description

technical field [0001] The invention relates to a cascade hydropower station group joint optimization control system. Background technique [0002] In recent years, with the formation and development of cascade reservoirs, the integration and compatibility technologies of multi-power stations and multi-application systems have been in-depth research, and the science and technology related to the centralized control automation system of cascade hydropower stations for hydropower development in the basin have also developed rapidly. [0003] In accordance with the State Economic and Trade Commission [2002] Order No. 30 "Regulations on Security Protection of Power Grid and Power Plant Computer Monitoring System and Dispatch Data Network" and "National Power Secondary System Security Protection Overall Plan", the technical requirements of multiple application systems During integration and data interaction, it is necessary to ensure the network security of the remote centralized...
