New description: [New technical field] This creation is related to a kind of generator device, especially a wind power generation device that has the protective effect of preventing cockroach operation. [Prior Art] According to the conventional windmill, the generator used is an induction generator and a permanent magnet synchronous motor. The induction generator is often a large windmill, and the small windmill has a minimum weight. The maximum power generation, so the permanent magnet synchronous (four) machine is usually used. In order to make the permanent-step generator lower than the joyful wind speed, it can use the variable frequency control loop (5) in Fig. 5 to control the speed, adjust the power angle of the generator (10), and make the speed close to the maximum operating efficiency of the windmill. At speed, the alternating current generated by the generator (60) is rectified into direct current. However, the variable frequency control loop (8) needs to drive the standby 'power' of the control element and the switching loss caused by the forward converter during operation, which consumes the electric energy generated by the part of the wind, thereby reducing the power generation of the windmill, and In the case of low wind speed, the power of the control loop may even be used to generate windmills. Half of the small windmills are often at a constant speed. Therefore, (4) back to _1) the annual power generation of the windmill is reduced. The active components in the price are much higher than the passive components, resulting in the price of the generator (10) not being reduced, reducing the price competitiveness of the small windmill.

And the outer part of the rotor is surrounded by a stator, and the stator comprises a high-power winding coil and a low-power winding coil, and the controllable saturation reactance H is connected to the high-power winding wire_output, and is connected to the low-shock winding coil output end. The saturated reactance H's saturable reactor is embedded with permanent magnets at the center to increase the magnetic flux of the saturable reactor, and the other ends of the two reactors are connected to the rectifying device. The main purpose of this creation is to change the DC voltage of the controllable saturable reactor according to the torque of the generator when the wind speed exceeds the rated value, thereby adjusting the inductance value of the controllable saturation reactance _ 进而 and then using the high power winding coil The reluctance reduces the rotational speed of the rotor, causing the motor 1 to rotate at the rated output power '俾 to prevent the generator from being overloaded. The purpose of this creation: the purpose of the owe is that the stator of the money is still low-power winding coils and high-power reliance, _ brewing (four) to turn it in the low wind fan and horse wind fan state, so that the power output of the generator Nearly the maximum energy efficiency of the windmill', the efficiency of power generation by low-temperature wind power is improved by the saturated electric reactor, and the M409302 adopts a controllable saturable reactor for torque control, and the controllable saturable reactor has a price-based price.

Device (5〇), when the wind speed exceeds the rated value, change the DC voltage of the controllable saturable reactor (4〇) according to the torque of the generator (1〇〇), thereby adjusting the controllable saturable reactor (4〇) The inductance value, in turn, uses the reluctance of the high-power winding coil (22) to reduce the rotational speed of the rotor (10), so that the generator (1〇〇) can maintain the rated output power, so as to prevent the generator (1〇〇) from being overloaded. The situation of burning. M409302. The actual production situation 'reviewed by the second and third ®, the blade (12) of this creation is rotated by the wind, and the rotor (10) is linked by the blade (10).

For further explanation, please refer to Fig. 2 'Fig. 2 is the graph of the power-generator speed of the motor and the generator's speed. The low-power winding of the stator (10) is used in the high-winding coil (22) with the coil and the stator (10). The induced voltage is determined by the speed of the rotor (10), so that the characteristic curve W2 of the low-power winding coil (21) can generate the power output W at low speed (the low speed is referred to as Fig. 2) And the characteristic curve W2 increases as the speed increases.

The magnetic permeability coefficient and the inductive reactance of the saturated reactor (30) decrease the characteristic curve of the low-power winding coil (21). W2 boosts power, and the high- and low-power winding coils (22) (21) and saturable reactors (30) increase the power generation efficiency of the generator (1〇〇), so as to increase the practicality. For another use case, please refer to Figure 4 for the diagram shown in Figure 1. Figure 4 is a graph of the torque-speed of the generator at each wind speed. In the figure, fr is the generator speed and T is the generator torque. (TVT3 is the torque at each wind speed), ywl~Vw3 is the curve from high wind speed to low wind speed, Lrl~L·3 is the curve from high inductance value to low inductance value, Wr is the rated power 'curve curve, when the wind speed exceeds the rated speed At the time of value, continuous speed control will cause the generator (100) to burn out due to overload. At this time, the high power winding coil (22) needs to replace the speed control with torque control to keep the power output of the generator (1〇〇). W is at rated power, wherein the controllable saturable reactor (40) of the present invention can be passively controlled at normal wind speed, and actively controlled at a rated wind speed, that is, according to the torque of the generator (1〇〇). The DC voltage of the saturable reactor (40) is controlled to reach the inductance value of the adjustable controllable saturable reactor (4〇). As shown in Fig. 4, when the set L is the rated wind speed, the wind speed Vw3 is raised to the wind speed L state. 'The inductance of the controllable saturable reactor (4〇) The value is actively reduced from Lh to thereby change the torque of the generator (1〇〇) from 71 to ,2, so that the speed of the generator (1〇〇) M409302 decreases 'by the rated power curve Wr, and when the wind speed is V· When decreasing to Ve, increase the inductance value of the controllable saturable reactor (10) from Lra to l, causing the torque of the generator (100) to decrease from T3 to T2, and also enable the generator (1〇〇) The power output is maintained at the rated value. By the structure of the above specific embodiment, the following benefits can be obtained: (1) when the wind speed exceeds the rated value, the DC voltage of the controllable saturable reactor (4〇) is changed according to the torque of the generator (100), thereby Adjust the inductance of the controllable saturable reactor (4〇), and then use the reluctance of the high-power winding coil (22) to reduce the rotation speed of the rotor (10), so that the generator (1〇〇) can maintain the rated output power.俾 to prevent the generator (丨〇〇) from being overloaded and burned; (1). The stator (2〇) of the Xuan 4 motor (1〇〇) is connected in parallel with a low-power winding coil (Μ) and a high-power winding coil (22) 'Xianglu, which makes it turn to low wind speed and 咼 wind speed respectively. The power output of the generator (100) is approached to the maximum energy efficiency, and the power efficiency of the generator (1〇〇) at low wind speed is increased by the saturation reactor (30), so as to increase its practicability. (3) The creation uses the controllable saturable reactor (10) to enter the Luft torque control, thereby achieving the overload protection of the generator (10), and the controllable saturable reactor (40) is more expensive and highly reliable.
