摘要

采用基于延迟最小均方(DLMS)的自适应控制技术，提出了与交流电网相连接的双模单级PV-DSTATCOM(光伏分布式静态补偿器)系统。本文提出的多功能PV-DSTATCOM系统工作在两种主要的工作模式下:1)DSTATCOM和2)PV-DSTATCOM模式。在模式1中，当没有光伏发电时，它作为DSTATCOM，缓解因负载电流总谐波畸变高而导致的公共耦合点的各种电能质量问题。在模式2中，它充当PV-DSTATCOM并将电力传输到交流电网和负载。为了实现双工作模式，在研制的实验室样机上实现了一种基于智能DLMS的自适应控制算法，并在不同条件下进行了多次实验测试。

Delayed LMS Based Adaptive Control of PV-DSTATCOM System

The dual-mode single-stage PV-DSTATCOM (Photovoltaic-Distributed Static Compensator) system tied to the AC grid is presented using a DLMS (Delayed Least Mean Square) based adaptive control technique. The proposed multifunctional PV-DSTATCOM system works under two main modes of operation: 1) DSTATCOM and 2) PV-DSTATCOM mode. In mode-1, when there is no PV power generation, it acts as a DSTATCOM for mitigating various power quality issues at Point of Common Coupling due to high Total Harmonic Distortion of load currents. In mode-2, it acts as a PV-DSTATCOM and transfers power to the AC grid and loads. For implementing the dual modes of operation, an intelligent DLMS based adaptive control algorithm is implemented on a developed laboratory prototype to carry out several experimental tests under varying conditions.
