Abstract

The invention discloses a topology structure and a control method of an AC / DC power generation system, belonging to the technical field of power generation, power transformation or distribution, whichis particularly suitable for occasions requiring direct current energy and alternating current energy of different voltage levels. The power generation system consists of a star The generator adoptstwo sets of stator windings, one set is open winding structure, two output terminals are connected with a power generation driving unit respectively, and the output terminals of the two power generation driving units are connected in series to form a three-wire bipolar bus bar, that is, a positive bus bar, a negative bus bar and a ground bar. The other winding directly outputs three-phase alternating current to form a multi-port AC / DC power generation system, which improves the shortcomings of single power supply form and single DC power supply voltage level in micro-grid and multi-electric aircraft, and can meet the requirements of different DC loads and load diversification in aircraft and micro-grid.

Description

technical field [0001] The invention discloses a topological structure and a control method of an AC / DC power generation system, belongs to the technical field of power generation, transformation or distribution, and is especially suitable for occasions requiring DC power and AC power of different voltage levels. Background technique [0002] With the global energy crisis and environmental pollution becoming more and more serious, distributed power sources such as photovoltaics and wind power have attracted more and more attention due to their renewable and clean advantages. It has become a development trend. At present, microgrids are mainly divided into two types: DC microgrids and AC microgrids, and DC microgrids usually have two types of power supply: unipolar and bipolar. Compared with the unipolar DC microgrid, the bipolar DC microgrid has two voltage levels, which can effectively improve the utilization rate of the DC power supply system and adapt to the access requi...
