3, well-known, the wind speed size of nature changes at any time, traditional wind-driven generator, in the transmission and conversion chains link of its whole energy, each functional unit needs to configure by the parameter of peak demand to meet its safety in utilization requirement, but in the most low wind speed time, can only exert oneself by Smaller load, there is the wasting of resources of installing greatly, namely year gas-to electricity hour number (conversion is to electric motor power at full capacity) is low especially, can only reach about 40% of general hydropower station unit.In wind energy turbine set of the present invention, the high pressure water that multiple wind turbine exports is concentrated and generates electricity, turbine-generator units, only need be equipped with by certain economics of scale to configure the total installation of generating capacity of water turbine set without the need to the arithmetic sum of the nominal output power by the wind turbine be incorporated to.When the wind speed of wind field exceedes predefined value; system arranges a certain proportion of wind turbine yaw out of service automatically; such system also can according to the full electric motor power generating preset in high wind speed district; simultaneously; high pressure pipe line can be arranged some pressure security protective gears; guarantee systems stay, work safely and steadly, system year gas-to electricity hour number can be improved significantly again.
4, traditional wind-driven generator, its Transmitted chains is short, and adequate rigidity, when wind speed mutation, unexpected impact injury can be caused to mechanical parts, occur that fatigue damage done sth. in advance by part, greatly reduce the whole service life of system.The present invention adopts waterpower transmission, transmission chain length, and rigidity is weak, and in the face of this sudden change wind, only propagate with the form of ripple in hydraulic transmission system, wink is moved and becomes soft, greatly reduces, improve the working life of system to the impact impact of mechanical parts.
5, for the electromechanical equipment in water power plant, only need select traditional suitable water turbine, just can realize, in wide head (i.e. the water outlet effluxvelocity of nozzle) excursion, obtaining high energy conversion efficiency.Traditional water turbine, generator, control system, auxiliary system, reliable performance, standardization level is high, and operating experience is enriched, and maintenance is easy, and the comprehensive advantages such as long service life are obvious.
