Research on Designation and Control System of A-NPC Three-Level Battery Power Storage Converter

Abstract:

The three-level converter based on A-NPC topology can improve waveform quality of the output voltage, decrease the switch voltage and reduce the loss of the inductor, thus it has broad application prospects in the electrical power storage domain. This paper built the semi-physical real-time simulation platform of A-NPC three-level battery power storage system by designing the control system and the main circuit of the A-NPC topology converter, and researched the control mechanism of the power storage converter control algorithm with digital simulation platform. The experimental results of the prototype machine show that the A-NPC three-level battery power storage system built in this paper was fine, compared with the most common two-level topology, three-level converter has characteristics of lower output current waveform distortion factor, lower current harmonics and higher efficiency. Three-level converter used in the power storage system is able to gain access to low THD during steady-state operation and fine dynamic characteristics.
