计及逆变器侧电流反馈影响的 LCL滤波器参数优化设计
LCL-filter Optimization Design With Consideration of Inverter-side Current Feedback Control Impacts
摘要
Abstract
LCL-type filters have been widely used in medium to high power level grid-connected inverters. However, this filter has several parameters which are closely related to each other and are hard to be decided. Moreover, the current controller and LCL parameters are interdependent and inter-restricted, because they determine the system stability and the current quality together. The existing design methods simply consider the filtering performance of LCL filters without taking into account the constraints raised by the current control. Thus, it is still difficult to optimize the parameters of LCL filters and current controllers. In this paper, based on establishing the model of grid-connected LCL-filtered inverters with single inverter-side current control, the constraints of control performances to LCL parameters were obtained. Furthermore, a novel design method integrated with LCL filter and current controller optimizations has been proposed. At last, experiments have demonstrated the effectiveness of the proposed design.关键词
