单相LCL型并网逆变器无阻尼控制策略
Undamped Control Strategy of Single-Phase LCL Grid-Connected Inverters
摘要
Abstract
The digital control system will bring system delay. Considering the control delay, to solve the single-phase LCL filter's resonance problem, an undamped control strategy for single-phase LCL type grid connected inverter is proposed. The grid connected current is controlled by grid side current feedback,which can not only realize the operation of the unit power factor, but also do not need additional sensors to reduce the cost. Based on the analysis of the feasibility of the control strategy,the calculation steps of the parameters of the undamped controller are given, and the correctness and validity of the undamped control strategy are verified by experiments.关键词
