Asynchronous generator is an alternator that uses the air gap rotating magnetic field between the stator and the rotor to interact with the induced current in the rotor windings. It is also called “induction generator” according to the working principle. The speed is slightly higher than the synchronous speed. The output power increases and decreases with the slip rate. Can be excited by the grid or self-excitation with power capacitors.
1.It is manufactured according to advanced techniques and standards, the generators feature high reliability and long operating life.
2.Matched with a lower power and loss frequency converter, making the entire turbine a higher efficient operation.
3.Being able to adjust the active and reactive powers smoothly.
4.A frame-type box structure box structure is adopted for the housing which ensures a high reliability of the generator during its operation.
5.The stator and rotor windings are vacuum-pressure impregnation processed so that the whole insulation performance of the generator is excellent and dependable, and also its mechanical strength is higher. A special insulation structure is used for the rotor, forming a strong ability against the high-frequency harmonic impulse from frequency converter.
6.The stator windings and bearings are fitted with the platinum the thermostat PT100 for monitoring and controlling the winding and bearing temperatures.
7.The bearings are quipped with an automatic grease-charging system and a manual grease-charging system, for user’s free operation selection.
8.The slipping system is fitted with a brush-worn alarm unit.
⑴Asynchronous generator-equipped power stations do not require a DC excitation system, the same period of installation, the power station investment costs are low.
⑵Since there are no slip rings, brushes, and rotor field windings, maintenance and operating costs are low.
(3) Asynchronous generator rotors are similar to rotor windings of hidden poles and non-synchronous generators, so their general efficiency is higher than that of synchronous generators with the same capacity and the same speed. Under the same water source, asynchronous generators can be used to generate more power.
上述 The aforementioned economic advantages of asynchronous generators will be partially offset by the excitation (or additional synchronous capacity or additional capacitors) required by the asynchronous generator.
⑸The magnitude of the excitation required by the asynchronous generator is inversely proportional to the rated speed of the motor (that is, proportional to the number of pole pairs of the motor). The higher the speed, the lower the standard threshold value of the excitation.
⑹The area of the asynchronous generator power plant is smaller than that of the synchronous generator power plant.
