Unit description The 100kw electric control wind turbine adopts the design scheme of horizontal axis layout, three blades, upwind direction, intelligent braking, automatic yaw, and direct-drive permanent magnet synchronous generator. The structure diagram is as follows ： Exploded view of wind turbine generator The wind turbine generator unit adopts automatic yaw and intelligent brake control to automatically wind up below the rated wind speed. When the wind speed reaches above the rated wind speed or other values (power, temperature, speed, etc.) reach the limit value set by PLC, the unit receives the signal and the intelligent brake intervenes to ensure that the wind turbine is in a safe and stable state. The wind turbine generator is mainly developed by direct-driven permanent magnet synchronous generator, and the power generation system adopts natural air cooling without internal cooling means; The blade is made of reinforced glass fiber reinforced resin, with light density and excellent fatigue strength and mechanical properties, and can withstand extreme harsh conditions such as storms and random loads ； The brake system uses intelligent sensor monitoring signals (speed, temperature, wind speed, etc.) for real-time monitoring. When an indicator reaches the set critical value, the intelligent brake will stop the fan; The yaw system adopts the active yaw design. Two independent sensors, anemometer and wind vane, are installed on the backpack at the rear of the cabin. The signal of the wind vane reflects the deviation between the fan and the main wind direction. When the wind direction continues to change, the controller controls the yaw motor to intervene according to the signal transmitted by the wind vane, and the yaw drive device rotates the engine room to align with the main wind direction. The PLC control system of the unit can automatically unwind the yaw when the yaw angle of the unit exceeds the specified value, avoiding the unit from twisting the cable. The yaw system is the main component of the wind turbine generator. The components of the whole system (yaw bearing, yaw motor, encoder, bearing, etc.) are of international and domestic well-known brands, ensuring the safety and stability of the system. The engine room of the unit adopts a humanized design scheme, with large working space and sufficient utilization rate, which is convenient for operators to inspect and maintain. The electrical system can adopt the special control inverter integrated machine with MPPT for wind turbine generator according to the customer's requirements, which has a wide range of input voltage, perfect protection function and optional GPRS remote computer monitoring function 。 Unit design level In the design of wind turbine generator units, the external conditions shall be determined by the installation site and site type. The safety level and corresponding wind speed and wind turbulence parameters of the wind turbine generator unit shall comply with the provisions of the following table. For wind turbine generator units that need special design (such as special wind conditions or other special external conditions), special safety level - S is specified. The design value of Class S wind turbine generator unit shall be determined by the designer and detailed in the design document. For such special design, the external conditions reflected by the selected design values are worse than the expected external conditions. Offshore installation is a special external condition, and wind turbine generator units are required to be designed according to Class S 。 Blade The blade is the most basic and key component of the wind turbine. Its good design, reliable quality and excellent performance are the decisive factors to ensure the normal and stable operation of the unit. The blade converts the aerodynamic energy into the mechanical energy of the impeller rotation under the lift of the air, which is an important part of the utilization of wind energy. The blades of this model are made of reinforced glass fiber reinforced resin with light density and excellent fatigue strength and mechanical properties, which can withstand extreme severe conditions such as storms and random loads. The impeller airfoil is designed according to the principle of aerodynamics. By modeling the analysis data and adopting Wilson's mathematical model to optimize the design of the chord length and twist angle of the blade, the 3D blade shape of the wind turbine is established to achieve the optimal design of the blade airfoil of the horizontal axis wind turbine. At the same time, the noise during operation is reduced and the utilization rate of wind energy is improved. Yaw System The fan yaw system is mainly composed of automatic yaw controller, anemometer, wind vane, rotary bearing, limit switch, rotary motor and other components controller 1.Control center of the whole system。 It is used to manage the input and output of wind turbine current, wind turbine brake, wind turbine unloading, wind turbine automatic yaw operation, abnormal protection and other controls 。 2．Temperature sensor Used to measure the internal temperature of wind turbine generator。 3．encoder It is used to count the number of turns for deflection, correct the deflection angle, and prevent excessive wire winding。 4．Wind vane Measure the direction of the wind to facilitate the realization of windward, crosswind and other functions。 5．Anemometer Measure the wind speed and feed it back to the controller according to the real-time wind speed。 6．Yaw motor Actuator used to drive the fan to deflect windward and crosswind。 7．Dump-load Control the output power to not exceed a rated value to protect the electrical equipment。 8．Internal mechanical brake Intelligent brake control. When the set conditions are met, the output controls the mechanical brake and stops the fan。 3.3.3 Generator 3.3.3.1 The generator is a component that converts the mechanical energy of impeller rotation into electrical energy. The 100 kw unit adopts high-efficiency multi-pole permanent magnet synchronous motor, which has the advantages of simple structure, reliable operation, high efficiency, small size, etc. The rated power of the generator is 100kw, the number of poles is 68, the rated voltage is 500V, and the insulation class of the winding is F. The generator is composed of stator, rotor, main shaft and other accessories. The generator stator is composed of stator core (silicon steel sheet), winding and other accessories; The rotor is composed of rotor core and permanent magnet. The generator winding is three-phase output, and three virtual slots are set, which can better reduce the torque of the generator. The specially designed unique arrangement on the rotor magnetic pole makes its vibration and noise lower during operation. The generator adopts passive natural air cooling, and the external wind in the air cools the winding through the stator core cooling teeth. When the external wind increases, the unit power increases, and the corresponding motor heat output increases, while the cooling efficiency also increases. Therefore, the temperature of the motor winding is kept at a relatively low level. At the same time, this cooling method does not require an independent fan or pump, which makes the overall efficiency and reliability of the motor higher. The stator winding material shall be insulation material of grade F or above, and the temperature rise shall be assessed according to grade B. The winding is soaked with high-performance polyesterimide insulation resin, and the excellent impregnation process ensures the insulation performance of the stator winding 。 3.3.3.2 Description of permanent magnet characteristics NdFeB （ Nd2Fe14B ） Permanent magnet material is called the third generation rare earth permanent magnet material, and is the highest performance permanent magnet material so far. With the development of production and manufacturing technology of permanent magnet materials, the performance of permanent magnet materials continues to improve and improve, especially the improvement of thermal stability and corrosion resistance of NdFeB permanent magnet, as well as the gradual maturity of research and development experience of permanent magnet motors, the performance degradation of permanent magnet can be avoided through the selection and design of permanent magnet and the design and control of magnetic circuit structure of the motor. The permanent magnet motor adopts high performance NdFeB permanent magnet material, and high enough coercivity can avoid the loss of magnetism at high temperature. In order to ensure the reliable magnetic properties of permanent magnets, the company's technical research and development department has done the following work: 1 、 1. The selection of permanent magnet has been checked and calculated by the magnetic property of high temperature short circuit demagnetization, and the working point is above the inflection point of demagnetization curve with a safety factor left; 2 、 2. When designing the generator, fully consider the demagnetization effect of the reverse magnetic field generated under special working conditions on the magnet. The performance parameters of the permanent magnet selected in the design can ensure that the working point of the permanent magnet is above the inflection point during overload, high temperature short circuit and lightning stroke, and the permanent magnet will not produce permanent demagnetization; 3 、 3. The control system of the wind turbine generator unit has multiple protection functions such as temperature, speed, overcurrent, undervoltage, etc. Under abnormal conditions, the control system of the unit makes the generator have perfect and reliable protection; 4 、 4. Strict and high standard technical terms for permanent magnet procurement have been formulated to ensure the performance of each piece of permanent magnet material through quantitative technical indicators, process quality control and scientific finished product sampling and testing; 5 、 Because NdFeB permanent magnet contains active rare earth elements, which are easy to oxidize and corrode, in order to improve its corrosion resistance, the surface of permanent magnet is galvanized, and a uniform and dense protective layer is formed on its surface through strict spraying process, significantly improving the corrosion resistance of permanent magnet 。 Payment Lieferdetails Rückholservice About us Contact us Payment 1.You can place an order and pay directly through eBay.
