Synchronous generator design method for realizing broadband rectification load by adding auxiliary winding

Abstract

The invention discloses a synchronous generator design method for realizing a broadband rectification load by adding an auxiliary winding, relates to the technical field of synchronous generators, and aims to solve the problems that an automatic voltage regulator of an existing synchronous generator is powered by an auxiliary exciter, but the capacity of the automatic voltage regulator for bearing capacity voltage change is relatively weak; in order to solve the problem that the stable operation of a generator is affected due to the fact that the automatic voltage regulator is damaged when the rotating speed changes greatly, the invention provides the following scheme: the design method comprises the following steps: adding an auxiliary winding coil on a generator stator winding to replace an auxiliary exciter to supply power to the automatic voltage regulator; the auxiliary winding supplies power to the automatic voltage regulator more stably than the auxiliary exciter, and stable operation of the generator is facilitated. The method is high in universality and high in practicability, and only the number of turns of the auxiliary winding needs to be designed, and the stator winding can be embedded together when the stator winding is embedded. Meanwhile, compared with an auxiliary exciter, the auxiliary winding provides stable power supply voltage for the automatic voltage regulator, and the cost is lower.
