Abstract
The utility model discloses a wind power generation device which comprises a synchronous motor. One inner side surface of the synchronous motor is provided with a rotor rack, and the other side surface of the synchronous motor is provided with a connection shaft. a supporting structure is arranged between the rotor rack and the connection shaft. The top of the synchronous motor and the inner side of the bottom of the synchronous motor are both provided with a connecting device which is fixedly connected with the synchronous motor. An excitation cable and a slip ring are respectively disposed on the connecting device on the top of the synchronous motor, wherein the excitation cable is equipped with a generator control device; the slip ring and the connecting device are detachably connected; and the slip ring is provided with a rotor winding. The connecting device on the bottom of the synchronous motor is provided with an impeller assembly which is equipped with a blade pitch control device. The wind power generation device has advantages of little space usage, high utilization rate of wind energy and uniform stress of blade tip. Meanwhile, permanent magnet excitation is changed to electric excitation. Thus, costs are saved, and exciting current can be adjusted at will.
Description
Technical field
The utility model relates to a kind of Blast Furnace Top Gas Recovery Turbine Unit (TRT), particularly a kind of wind power generation plant.
Background technology
Wind-driven generator be a kind of by wind energy transformation, be mechanical energy, and then drive the equipment of generator generating.Existing generator is generally divided into horizontal axial type wind-driven generator and perpendicular axis type wind-driven generator, these two kinds of generators conventionally all have larger volume and take more space, and in the situation that wind-force is lower, wind-force is not enough to drive generator generating, there is the situation that wind energy utilization is not high, general wind-driven generator adopts permanent magnet excitation mostly simultaneously, permanent magnet is embedded into after rotor core, be fixed on rotor field spider, but permanent magnet involves great expense, be unfavorable for the saving of cost, and this excitation mode is unadjustable.
Utility model content
The purpose of this utility model is just to provide a kind of wind power generation plant, can address the above problem completely.
To achieve these goals, the technical solution adopted in the utility model is such: wind power generation plant of the present utility model, comprise synchronous machine, in synchronous machine, a side is provided with rotor field spider, its another side is provided with connecting axle, between rotor field spider and connecting axle, be provided with supporting construction, synchronous machine top and bottom inside are equipped with jockey, jockey adopts and is fixedly connected with synchronous machine, on the jockey at its synchronous machine top, be respectively equipped with excitation cable and slip ring, excitation cable is provided with generator control unit, slip ring and jockey adopt and removably connect, slip ring is provided with rotor winding, the jockey of its synchronous machine bottom is provided with impeller sets, impeller sets is provided with vane propeller-changing device.
As preferably, described excitation field power supply that cable connects is DC power supply.
As preferably, described excitation cable is connected to the DC power supply in wind power generation plant in rotor winding by slip ring.
Compared with prior art, the utility model has the advantage of: this wind power generation plant is converted into electric energy by wind energy, and transformation efficiency is high, take up room little, blade tip is stressed evenly, permanent magnet excitation is changed into electric excitation simultaneously, not only cost-saving, and exciting current can regulate arbitrarily.Excitation field power supply that cable connects is DC power supply, can better drive Blast Furnace Top Gas Recovery Turbine Unit (TRT) work; Excitation cable is connected to the DC power supply in wind power generation plant in rotor winding by slip ring, makes exciting current adjustable.
