Abstract

The invention discloses a blade electro-hydraulic adjustment method and device of a high-oil-pressure control water turbine. A fuzzy mathematic model is established for a selected blade angle calculation method according to hydropower station hydrologic data and unit parameters. Then, a high-oil-pressure control blade adjustment electro-hydraulic actuator adjusts a rotating blade to the calculated angle according to changes of the water head and flow, and therefore high hydraulic energy conversion efficiency is obtained, and the target of the maximum annual energy output of a high-oil-pressure control blade angle rapid adjustment hydroelectric generating set is achieved. According to the key technology, a high-oil-pressure control system is adopted for the turbine blade adjustment actuator, a standard ball floating seal is adopted, and therefore the problem of oil leakage of a high-oil-pressure rotating sealing device is completely solved. The blade electro-hydraulic adjustment method and device fill in technical gaps in controlling blade adjustment by a Kaplan turbine through the high-oil-pressure speed controller system, and great technical innovation is achieved for the structural design of the water turbine.

Description

technical field [0001] The invention relates to a blade electro-hydraulic adjustment method and device of a high oil pressure controlled water turbine. The paddle-adjustable water turbine between the rotary paddle type water turbine and the fixed paddle type water turbine is controlled by a high oil pressure governor system, and the dynamic Adjust the running angle of the blades, so that the hydroelectric generating set can operate at a suitable angle in different operating conditions, and always obtain high water energy conversion efficiency. Background technique [0002] Today's energy situation is tense. The depletion of non-renewable resources such as petroleum and coal has made people increasingly dependent on renewable resources. This is the main reason why hydropower, wind power, and solar power can flourish. Among the many renewable energy sources, hydropower is the most economical. With the extensive development of medium and high head hydropower stations, the re...
