摘要
在实际工程应用中,需要利用稳定性判据判断直流分布式电源系统(directcurrentdistributedpower system,DCDPS)的稳定性,以便采取合适的控制策略。因此,DCDPS稳定性判据成为国内外学者研究的热点。对基于等效源变换器(子系统)和负载变换器(子系统)的稳定性判据、基于母线电压控制变换器和母线电流控制变换器的稳定性判据、基于无源性的稳定性判据、大扰动信号情况下稳定性判据的基本思想、特点进行分析。指出这些稳定性判据的优点与不足,给出了DCDPS稳定性判据研究的趋势,提出了基于无源性的稳定性判据和其他判据相结合的稳定性判断新方法。
In practical engineering application, it is necessary to judge the stability of direct current distributed power system(DCDPS) by using stability criteria, so as to adopt appropriate control strategies. Therefore, stability criteria of DCDPS are generally interested by scholars at home and abroad. The basic idea and characteristics of stability criteria based on equivalent source converter(subsystem) and equivalent load converter(subsystem), a bus voltage-controlled converter and a bus current-controlled converter, passivity and large disturbance signal were analyzed. Based on the above analysis, the advantages and defects of the stability criteria were pointed out. The research trends of the stability criteria for DCDPS were put forward, and a new method of stability criteria was proposed by combining passivity-based stability criterion and other stability criteria.
