Abstract

The invention belongs to the technical field of generators, and particularly relates to a passive self-excitation constant voltage brushless synchronous generator and a control method thereof. The generator mainly comprises a main electricity generation armature, a main generator rotor, an exciter stator, an exciter armature, a rotary rectifier module, a control box and an automatic voltage regulator (AVR). By means of residual magnetism of an exciter stator core, the problem of generator excitation and the constant voltage problem caused by load changes, rotating speed changes and the like are solved, complete self-excitation is ensured, and an external direct-current power or an auxiliary exciter is omitted.

Description

technical field [0001] The invention belongs to the technical field of generators, in particular to a passive self-excited constant voltage brushless synchronous generator and a control method thereof. Background technique [0002] At present, there are mainly two types of brushless synchronous generators produced at home and abroad: one is a brushless synchronous generator with an AC excitation machine; the other is a three-machine generator with an AC main exciter and a permanent magnet auxiliary exciter. Coaxial brushless synchronous generator. The former exciter requires external power supply, which is not convenient for field work; the latter is the problem of permanent magnet demagnetization, which is difficult to overcome in the existing technology, and the strong excitation and dynamic performance are limited. Contents of the invention [0003] The object of the present invention is to provide a passive self-excited constant-voltage brushless synchronous generator...
