Description
Technical field
The present invention relates to a kind of brushless self-excited three-phase induction generator.
Background technology
The formation of the self-excitation induction generator of traditional independent operating as shown in Figure 3.Its operation principle is as follows: under the situation of zero load, drag rotor 7 rotations with prime mover, make remanent magnetism magnetic field " cutting " stator winding 9 of cage rotor 7, induction remanent magnetism electromotive force in stator winding 9, and send capacity current to shunt capacitance 8, capacity current flows through and will produce consistent with remanence direction magnetic stator magnetomotive force and the magnetic field of increasing behind the stator winding 9, and air-gap field is strengthened, and the voltage of generator is progressively set up, the self-excitation process of Here it is induction generator.After but this generator connected load, output voltage changed with the variation of load current, and change in voltage is big.Main cause is that load current is directly related with exciting current, and exciting current is directly related with output voltage, so load current and output voltage form the relation of positive feedback, so output voltage changes with the variation of load current.
Summary of the invention
The purpose of this invention is to provide a kind of brushless self-excited three-phase induction generator with series compensating function, after overcoming traditional self-excitation induction generator connection load, output voltage changes with the variation of load current, the defective that change in voltage is big.It is by generator unit stator 1, cage rotor 2, threephase stator winding 3, three phase excitation winding 4, three exciting capacities 5 and three series compensation capacitances 6 are formed, threephase stator winding 3 is arranged on the inner surface of generator unit stator 1 and is symmetrical three phase windings, three phase excitation winding 4 is arranged on the inner surface of generator unit stator 1 and is symmetrical three phase windings, three exciting capacity 5 Y-connections or triangle connections also form three terminals 5-1, a corresponding terminals 5-1, the corresponding end that connects a series compensation capacitance 6 of every end of three output 3-1 of threephase stator winding 3 of connecting of every end of three exits of three phase excitation winding 4.When the present invention works, on the end of the three-phase input end of the corresponding connection of the every end load of the other end of three series compensation capacitances 6.Generator of the present invention mainly provides exciting current by three phase excitation winding 4 and exciting capacity 5, is adjusted and is compensated by 6 pairs of output voltages of three series compensation capacitances during bringing onto load.Threephase stator winding 3 and three phase excitation winding 4 are symmetrical three phase windings.If threephase stator winding 3 and three phase excitation winding 4 are star connection, Y connection in generator inside, then the neutral point of the two can be bound up, otherwise on generator unit stator 1 mutually insulated, do not have the contact of electricity between the two.Owing to mainly undertake excited work by three phase excitation winding 4 in the generator of the present invention, and exciting current and load current are contacted directly not, so load current do not have positive feedback to concern with output voltage, and the output voltage variation is little.Cost is low, reliability is high and constitute characteristics such as simple because this generator has, and is independently having a good application prospect in wind generator system, miniature hydro-power generation system and the distributed power supply system.
