Hydropower station remote real-time control system and method based on new generation communication technology

Abstract

The invention discloses a hydropower station remote real-time control system and method based on a new generation communication technology, and the method comprises the steps: employing the high-speed and low-delay characteristics of new generation communication (such as 5G), and connecting a first local area network server group of hydropower station control equipment and a second local area network server group of centralized control center control equipment; arranging an intranet server, an extranet server and a network one-way isolation device arranged between the intranet server and the extranet server, so that safe, high-speed and low-delay special link communication is established, and high-speed data transmission between a remote centralized control center and hydropower station control equipment is realized. Therefore, a safe, efficient, rapid and reliable real-time remote control method is realized, the remote control problem of the hydropower station is solved, and the requirements of synchronous acquisition of remote operation data and low-delay real-time control of the hydropower station are met, so that safe and reliable remote control of a hydropower station group is realized, and the investment and operation management cost of the hydropower station group is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of hydropower station control, in particular to a remote real-time control system and method for a hydropower station based on a new generation of communication technology. Background technique [0002] With the increase of society's demand for electricity and the improvement of people's awareness of environmental protection, the importance of hydropower has gradually increased. The hydropower reserves of my country's rivers reach 680 million kilowatts. At present, 340 million kilowatts of developed installed capacity have been developed, and the annual power generation capacity is 1.2 trillion kilowatt-hours. China ranks first among all countries in the world in terms of the reserves of hydropower resources and the potential development of hydropower resources. [0003] At present, my country has built more than 47,000 small hydropower stations with an installed capacity of less than 50,000 kilowatts, with...

Problems solved by technology

However, in the existing technology, when performing remote control analysis and remote real-time control on the operation data of the hydropower station, on the one hand, in view of the importance and high confidentiality of the operation data of the hydropower station, the operator needs a lot of manpower and material resources to collect the operation data on the spot. For the state analysis and data statistics of hydropower station control equipment, this method is costly and inefficient, and the state analysis delay of hydropower station control equipment is high, which leads to the low value of the analysis results and seriously affects economic benefits; on the other hand, in the process of The remote real-time control of hydropower stations often requires coordination and cooperation between multiple hydropower stations. Based on the existing on-site remote real-time control methods, the remote real-time control progress among multiple hydropower stations is not uniform, and the remote real-time control of the hydropower station system cannot be achieved. Due to the requirement of delay error accuracy, the reference value of remote real-time control results is not high, which seriously affects the maintenance of hydropower station control equipment
