虚拟同步机逆变器等效方式及滤波电路影响分析OA北大核心CSCDCSTPCD
Analysis of influences of equating ways and filter circuits for virtual synchronous generator-based inverter
基于逆变器的虚拟同步机(virtual synchronous generator,VSG)特性不但取决于控制策略,而且其等效方式及滤波电路对VSG动稳态行为与模型准确性的影响也是不可忽略的.本文重点对LCL滤波电路下不同等效方式的VSG特性进行了分析对比,并发现将包含LCL滤波电路整体的VSG逆变器完全等效为同步发电机(synchronous generators,SG)建立的模型存在误差,进而提出一种VSG逆变器准确建模的等效方法,通过该方法…查看全部>>
The characteristics of inverter-based virtual synchronous generator (VSG) not only depend on control strate-gies but also are effected by the manner of equating and filter circuit. This paper focused on analyzing and studying comparatively performances of VSGs, which are in different equivalent modes and equipped with LCL filter circuits. Consequently, it was found that there are errors in the model established through regarding inverter and whole LCL circui…查看全部>>
