中文摘要

有源电力滤波器(APF)在补偿非线性负载电流谐波方面发挥重要作用。本文采用具有高性能和快速动态响应的无差拍控制(DBC)作为APF的电流控制器。通过引入一种改进的无差拍控制(Imp_DBC),有效抑制了电流采样误差带来的不利影响,并增强了系统的抗干扰能力。

English Abstract

An active power filter (APF) plays an important role in compensating the harmonic component of a nonlinear load current. In this paper, deadbeat control (DBC), which has high control performance and fast dynamic response, is used as a current controller for an APF. An improved DBC (Imp_DBC) is introduced to suppress the adverse effect of the current sampling error and to enhance the interference r...

该技术对阳光电源的并网逆变器及储能变流器(PCS)产品线具有重要参考价值。无差拍控制(DBC)以其快速动态响应著称,但在实际应用中易受采样噪声和参数扰动影响。本文提出的误差补偿机制可直接优化阳光电源组串式逆变器及PowerTitan系列PCS在复杂电网环境下的谐波抑制能力与电流跟踪精度。建议研发团队在iSolarCloud智能运维平台的电能质量分析模块中引入此类控制策略,以提升产品在弱电网场景下的并网适应性与电能质量治理水平。
