Abstract

The grid interconnection of renewable energy source is a popular issue in the electric utilities. Different types of converter topology in grid interconnection have been improved by researchers to improve power quality and efficiency of the electrical system. The main contribution of this paper is that shunt hybrid active power filter (SHAPF) with a DC-DC converter at dc link is to provide interconnection between renewable source and grid with linear dynamic loads. The other contribution of this paper is to present a novel control strategy for reactive power compensation and harmonics elimination in industrial networks using a hybrid active power filter as a combination of a three phase, two level voltage source converter connected in parallel with single tuned LC passive filter. In proposed control method, reactive power compensation is achieved successfully with perceptible amount. Besides, the performance results of harmonic compensation are satisfactory. Theoretical analyses and simulation results are obtained from an actual industrial network model in PSCAD. The simulation results are presented for proposed system in order to demonstrate that the harmonic compensation performance meets the IEEE-519 standard.

并网条件下谐波和动态无功补偿的并联混合有源滤波器控制新方法

可再生能源并网是电力领域的热点问题。为了提高电力系统的电能质量和效率，研究人员对电网互连中不同类型的变换器拓扑进行了改进。本文的主要贡献在于，在直流链路上配置dc - dc变换器的并联混合有源电力滤波器(SHAPF)可提供具有线性动态负荷的可再生能源与电网之间的互联。本文的另一个贡献是提出了一种新的控制策略，用于工业网络中的无功补偿和谐波消除，该策略使用混合有源电力滤波器作为三相，两电平电压源转换器与单调谐LC无源滤波器并联的组合。在该控制方法中，以可感知的量成功地实现了无功补偿。此外，谐波补偿的性能也令人满意。基于PSCAD的实际工业网络模型进行了理论分析和仿真。仿真结果表明，该系统的谐波补偿性能符合IEEE-519标准。
