Description
Technical field
The present invention relates to a kind of wind generating unit, be specially a kind of Intelligent reducing self-starting vertical axis wind power generation device.
Background technique
Wind energy is a kind of clean, very abundant renewable energy sources of reserves, is a kind of reformulations of solar energy in essence.The type of wind energy conversion system, according to the position of wind mill wind wheel rotating shaft and wind direction, can be divided into horizontal-shaft wind turbine and vertical axis windmill.With horizontal-shaft wind turbine, compare, vertical axis windmill can receive the wind comes from of any direction, without to wind apparatus, other parts of wind wheel and transformation of energy, as gear, generator etc., can install easily on the ground, thereby not need to set up expensive pylon, and be convenient to safeguard, maintain, thereby manufacture and operating cost have been reduced.Therefore, vertical axis windmill becomes the first-selection of small-sized wind power generator gradually, and the research vertical axis windmill has practical significance and good application prospect widely.
Because wind energy has randomness and uncertainty, cause the utilization ratio of wind energy not high, the wind speed round of wind energy conversion system changes soon with wind speed, causes output voltage to change greatly, fluctuate soon, brings certain difficulty to the safe and stable operation of wind energy conversion system and follow-up electric energy processing.Simultaneously, angle from wind-power electricity generation maximal power tracing (MPPT---Maximum Power Point Tracking), due to for a specific wind speed, wind energy conversion system only operates under a specific mechanical angle speed, and wind energy conversion system just can obtain maximum energy conversion efficiency, therefore, for different wind speed, need to regulate the wind energy conversion system rotating speed, the blade tip linear velocity of wind wheel blade and the ratio of wind speed are remained unchanged, thereby reach the purpose that MPPT controls.For general wind energy conversion system, can utilize generator torque control and yaw system to change the rotating speed of wind energy conversion system, and, for vertical axis windmill, owing to there is no yaw system, can only control rotating speed by the regulator generator torque.The subsequent treatment to generator output electric energy just is based in the research of regulating for generator torque at present mostly, recently control the electromotive power output of generator by the duty of regulating DC/DC transducer trigger impulse, and then controlling torque, realize variable-speed operation, reach the purpose of wind-driven generator MPPT maximum power point tracking.That is: increase the dutycycle of trigger impulse, the electric power be transferred in load will increase, and the mechanical output of generator input is less than the electric power of output, and rotating speed will reduce; In like manner, reduce the dutycycle of trigger impulse, the electric power be transferred in load also will reduce, and the mechanical output of generator input is greater than the electric power of output, and rotating speed will raise.
The adjusting of DC/DC transducer trigger impulse dutycycle changes and need to change corresponding with the output power of wind energy conversion system by control algorithm, when wind speed changes faster, wind mill wind wheel rotating speed respective change strengthens, cause the output power of wind energy conversion system to change soon, calculate and export in time to control and bring difficulty to the Accurate Analysis of dutycycle.Safe and stable operation in order to ensure wind generating unit, also in order more effectively to realize that MPPT controls, all need the how more effective controlling method for generator torque, make the wind speed round of wind energy conversion system can be stabilized according to the wind speed of continuous variation certain rotating speed interval as far as possible, keep certain proportional relationship as far as possible, unlikely generation sudden change, thereby both avoided the quick-wearing of crossing of the various mechanical transmission component of wind energy conversion system, especially guarantee in time device security when wind speed is excessive, can give full play to the maximum effect of MPPT control algorithm again, avoid causing MPPT maximum power point tracking not in time or control the fault of makeing mistakes occurring because the wind speed round variation is too fast.
The blade of the vertical axis windmill of straight wing type structure adopts the wing blade section configuration of aircraft, that the running torque of utilizing air lift to produce is carried out work, although the resistance-type vertical axis wind turbine that generating efficiency Billy produces running torque with resistance of air is high, there is the deficiency of difficulty in starting.In order to improve the startability of lift vertical shaft wind energy conversion system, mostly adopt at present and rise resistance composite blade structure, the angle by adjusting vane with respect to rolling tangential, realize the conversion of lift-type and resistance type, cause wind wheel organization too complicated, be unfavorable for the long-term stability operation of wind energy conversion system.Can on the basis that does not change lift vertical shaft wind mill wind wheel structure, realize the self-starting operation of wind energy conversion system by the method for additional assistant starting moment, be a kind of method safely and effectively.
