Research Of The Remote Computer Monitor System Of Hydroelectric Stations' Cascading Dispatch

With the rapid development of the electric power industry, waterpower, as a clean reproducible energy source, has become a important part of the power industry. Rational utilization and scientific dispatch of the hydraulic resource remain to be the most important research task of power system. Today the exploiture of the hydraulic resource is developing to large-scale and river basin mode, so the rational layout and exploiture, building more cascade Hydroelectric Stations and enlarging scale, will play an important role in the areas of drought and flood prevention, water resource management, and water and soil preserving. More importantly, these will bring a massive economic benefit to the power corporation。 By the united cascading dispatch for the river basin, the power dispatching department can alleviate the conflict between the power networks' plenty-drought period and peak-valley time by a long way. The river basin cascading hydroelectric stations are far from each others, far from the dispatch centre and the charge centre. The computer monitor system can meet the requests of the measurement, management and control of the stations' working field, and the request of the dispatch's automation. But to carry out the cascading dispatch of the whole river basin, the remote computer monitor system is the necessary method.The top classes of the cascading hydroelectric stations studied in this paper are thereservoirs that possess the long-term dispatching ability, and the other stages are the reservoirs only possessing the daily dispatching ability. The cascading hydroelectric stations in this condition are popular both in our country and the others. Do not like the other cascading stations, these stations' computer monitor system have the simplest economical function mode. This paper put the emphasis on the key techniques of the remote monitor based on the field monitoring: traditional control networks combining with the Internet, the theory of the remote computer monitor system and its resolvent -the B/S structure base on the web explorer, and the system's design. At the same time it provides a practical scheme according with the factual status of the hydro-stations. The construction of this monitor system eases the managers' dispatch and decision-making. Under the safety condition of the net, by internet, managers can monitor the system everywhere. This system is not only for the power system's monitoring, but for other industry monitoring it is helpful either.
