Multi-electricity system generator set

Abstract

The invention discloses a multi-electricity system generator set, which comprises a prime mover, a synchronous generator, a main driving shaft, a variable speed gear box, an auxiliary driving shaft and a rotary transformer, wherein the synchronous generator is internally provided with generator stator three-phase windings, an input end of the variable speed gear box is connected with the main driving shaft, an output end of the variable speed gear box is connected with the auxiliary driving shaft, the tail end of the auxiliary driving shaft is connected with the rotary transformer, the rotary transformer comprises a rotary transformer rotor, a rotary transformer stator and a slip ring, the rotary transformer rotor is provided with rotor three-phase windings, the rotary transformer stator is provided with stator three-phase windings, the stator three-phase windings are connected with the generator stator three-phase windings by means of change-over switches separately, and the slip ring is provided with a plurality of rotary transformer wire-outgoing terminals which are connected with the rotor three-phase windings. The multi-electricity system generator set integrates the prime mover, the synchronous generator and the rotary transformer, can realize the frequency conversion and voltage transformation functions of the generator set, saves a complicated and expensive electric power electronic frequency conversion device, is an economical and reliable frequency-conversion voltage-transformation power generation system, and can be used in a multi-electricity-system power supply system, such as port on-shore power supply, power generation ships and the like.

Description

technical field [0001] The invention belongs to the technical field of generating sets, and in particular relates to a multi-power generating set. Background technique [0002] At present, diesel or LNG generator sets generally only output one voltage and frequency, and units with different voltages and frequencies must be used to meet customer requirements for different needs. [0003] Especially in the occasions where variable frequency and variable voltage power generation is required, the user has to equip two sets of units or change the winding wiring and AVR controller, which is costly, inconvenient to operate and cannot guarantee safety. [0004] Therefore, in the occasion where variable frequency and variable voltage power generation is required, a generator that can be compatible with various electrical systems is required. Contents of the invention [0005] The purpose of the present invention is to design a multi-power generator set according to the deficiencie...
