Five, embodiment
Shown in Fig. 1,2, concentrated cooling type wind driven generator system of the present invention comprises cooling unit 1, recycle pump 2, wind-driven generator 3, cooling medium delivery pipe 4 and the cooling medium recovery tube 5 that is arranged in the wind power plant, and wind-driven generator 3 wherein comprises stand 6, wind wheel 7, lower velocity shaft 8, gear-box 9, gear-box heat exchanger 10, high speed shaft 11, control frequency variator 12, control frequency variator heat exchanger 13, generator 14, generator heat exchanger 15, cooling medium 16 and cabin lid 17; It is characterized in that cooling medium 16 is by the 1 concentrated cooling of cooling unit, send into each wind-driven generator 3 by cooling medium delivery pipe 4 then, circular flow will be taken away by the heat that they produce through the heat exchanger that is arranged on gear-box 9, generator 14 and control frequency variator 12 outsides, returning cooling unit 1 by cooling medium recovery tube 5 at last cools off, circulation has repeatedly according to this guaranteed efficient, stable, the safe long-term work of wind power generating set.
During wind-driven generator work, wind wheel rotates under wind-drive, and its rotating speed reaches gear-box 9 by lower velocity shaft 8 and carries out speedup, and the high speed shaft 11 of process speedup connects with the rotor of generator 14 inside, drives rotor high-speed rotation and cutting magnetic line and produces electrical potential energy.Motor speed fluctuation and the frequency of supply that causes changes when wind-force changes meanwhile guarantees that the electric power of delivering to power supply-distribution system satisfies the requirement of being incorporated into the power networks, and also needs to be equipped with 12 pairs of frequency of supplies of control frequency variator and automatically adjusts.In above-mentioned generator system working procedure, gear-box 9, generator 14, control frequency variator 12 can produce a large amount of heats, if there is not suitable cooling method, will cause the serious consequence of burning when temperature surpasses certain limit.Work in the operating temperature range that allows in order to ensure these parts, guarantee the generator set safe operation, gear-box heat exchanger 10, generator heat exchanger 15 and control frequency variator heat exchanger 13 need be set respectively in the outside of gear-box 9, generator 14 and control frequency variator 12, will take away with the heat that upper-part produces by the cooling medium 16 of each heat exchanger of flowing through.Cooling medium 16 after temperature raises is sent into the cooling unit 1 that is arranged in the wind power plant by cooling medium recovery tube 5 and is concentrated cooling, send into each wind-driven generator 3 via cooling medium delivery pipe 4 then, each parts is carried out next round circulation cooling, thereby guaranteed efficient, stable, the safe long-term work of wind power generating set.
In order to reduce the conveying energy consumption of cooling medium, can in wind power plant, build the platform that is used to set up the cooling unit, make cooling unit and each wind-driven generator be in sustained height.In actual applications, the cooling unit can be selected dissimilar air-coolers or cooling machine set for use, with respect to air-cooler according to the cooling requirement of generator, adopt cooling machine set can obtain lower chilling temperature, help Development of New Generation high-power wind-driven generator system.When separate unit cooling unit can't satisfy the refrigerating capacity demand, many units can be set, and when factors such as weather, seasonal variations cause the refrigerating capacity demand fluctuation, can carry out free adjusting as long as change equipment operation platform number., generating board number many wind power plant wide for floor space, also can in different proper site the centralized cooling unit in many places be set according to actual conditions, to satisfy cooling requirement and reasonable disposition cooling medium conveyance conduit better, obtain the high reliability and the Economy of operation.And for the lower occasion of wind-driven generator operating temperature, in order to reduce the cold consumption that causes in the cooling medium course of conveying, can adopt the tubing of excellent heat insulating performance and be equipped with certain insulation, as managing outer wrapping heat insulation layer etc.In addition, can adopt bellows to be connected with the joint of wind-driven generator, thereby adapt to wind-driven generator rotates fuselage because of the change of wind direction in real work situation better at cooling medium conveying, recovery channel.
Compare with air blast cooling, the water-cooled unit group cooling type wind driven generator system of present employing, concentrate cooled wind-force Although generator system has increased the expense of laying cooling medium pipeline and consumption and the conveying cooling medium of cooling medium Required energy consumption, but it has the outstanding advantages such as simple in structure, that regulating power is strong, reliability is high, operating cost is low, and And can adopt flexibly various refrigeration modes according to the wind turbine equipment service requirement, for wind-driven generator provides best worker Make temperature, not only significantly increased wind power generation efficiency, and service life that can also extension device, thereby minimizing equipment Maintenance cost, improved the economy of wind-power electricity generation. In addition, with the diffusing cooling type wind driven generator system phase of unit component Ratio, this system simplification the cooling device of wind-driven generator inside, reduced the own wt of operation, more be conducive to wind-force The high-level operation of generator also brings great convenience to system's installation, maintenance. In addition, for because of season, gas When the changes such as time cause the refrigerating capacity changes in demand, only need regulate to the cooling unit getting final product, and need not one by one to each typhoon Power generator operates, and the control difficulty reduces greatly.
