摘要

随着电力电子装置的广泛应用和多种分布式能源的接入

低压配电网的电能质量问题已日益突出。为改善多馈线型低压配电网公共连接点(PCC)处的电能质量

降低其电压谐波失真

以具有谐波补偿功能的单相光伏并网设备为基本单元

构建了一个分布式有源滤波系统。通过分析低压配电网中各馈线对PCC处电压谐波的责任

对各馈线的谐波补偿任务进行了优化调整。此外

采用基于虚拟谐波阻抗的下垂控制方法

实现了多设备并联时的自主协调

并提出了一种参考PCC处谐波责任的谐波补偿容量分配算法

提升了在输出容量限制情况下分布式有源滤波系统的谐波补偿效果。最后

通过软件对上述模型和控制策略进行了建模与仿真

仿真结果验证了该系统的可行性和有效性。

Abstract

With the extensive application of power electronic devices and the access to distributed energy

the power quality problem of low-voltage distribution network is becoming more and more serious. In order to improve the power quality at the point of common coupling (PCC) in the low-voltage distribution network with multiple harmonic feeders

a distributed active power filter system is created. By estimating the contribution of each harmonic feeder to the voltage harmonic distortion on PCC

the harmonic compensation duty of each feeder is optimized. Furthermore

by adopting the virtual harmonic impedance based droop control

autonomous coordination between multi-function devices is achieved

and an optimization algorithm for the capacity allocation of the harmonic compensation is proposed with reference to the harmonic contribution. In the end

the effectiveness of the proposed model is verified by simulation results. This work is supported by Fundamental Research Funds for Central Universities (No. 0800219170).
