基于动态扇区双开关表直接功率控制研究
Research on Direct Power Control Based on Dynamic Sector Dual Switch Table
摘要
Abstract
Based on the analysis of the problem that the DC side voltage and the reactive power fluctuate by using a switch table based on the dynamic sector traditional direct power control strategy,the switch vector was optimized and the DPC control strategy based on the dynamic sector improvement switch table was adopted. By introducing a three state hysteresis comparator and a power amplitude control function,a new dynamic sector dual switch table model was designed. According to the specific power demand of the system,the switch table and the switch vector could be selected properly to produce the corresponding working mode of the switch signal control system,so as to achieve the purpose of fast tracking the system specified power. At the same time,the new scheme of fast partitioning dynamic sectors was also improved. Finally,the Matlab/Simulink simulation model and experiment show that the dual switch table can improve the output dynamic characteristics of rectifier and reduce reactive power ripple.关键词
