“…In [7], the authors reported results of an experiment involving synchronized measurements at large industrial plant facilities. Furthermore, in [8], by utilizing GPS synchronized PQ recorders installed as part of a real high voltage (HV) network, the authors investigated the phenomena of dynamic interaction of harmonic sources with special attention given to the grid code compliance.…”

This paper focuses on studying the phenomenon of harmonic distortion propagation through distribution networks. This phenomenon is governed by a combination of factors involving the nature of harmonic loads and their dynamic interaction, the influence of background voltage distortion, and harmonic impedance values. The objective of the proposed research includes evaluation of the network response at different nodes to harmonic current injections via utilizing a time-synchronized distributed measurement system. The study is performed in a fully controlled and flexible test network with three medium voltage/low voltage (MV/LV) distribution substations and several managed LV harmonic sources, namely PV inverter, single-phase EV charger and emulated harmonic load with reference current injections. A selection of the results is analyzed and interpretation of the observed phenomena is given with implications that synchronized harmonic measurements can be considered as potential powerful instruments for analyzing power quality disturbances.

“…Além disso, os sistemas elétricos enfrentam uma mudança de paradigma com a inserção crescente de fontes alternativas de energia como a eólica e solar (Chishti et al, 2019), (Triviño-Cabrera et al, 2017), (Peterson et al, 2017). Apesar dos seus múltiplos benefícios, como o aumento da matriz energética do país, essas fontes são associadasà uma notável intermitência eà diversos problemas de qualidade de energia, incluindo o aparecimento de distorções harmônicas (Peterson et al, 2017). Consequentemente, há uma necessidade de prover meios para a modelagem e representação dos componentes do sistema de potência no domínio da frequência (Variz et al, 2008), (Variz et al, 2012), (Levačić et al, 2019), (Melo et al, 2020), (de Melo et al, 2019), (Sharma et al, 2018).…”

Este trabalho compara modelos matemáticos utilizados para representação de uma linha de transmissão real, trifásica e transposta do sistema elétrico de potência brasileiro analisada no domínio da frequência considerando distorções harmônicas de tensão e corrente. Para tanto, é utilizado o modelo $\pi$ equivalente em componentes de fase, com correção hiperbólica, que garante a exatidão dos parâmetros da linha mesmo com a variação da frequência. Além desse modelo, são utilizados dois métodos desacoplados os quais representam modelos simplificados de transformação modal valendo-se da teoria de componentes simétricas de Fourtesque e de Clarke. Neste artigo, o desenvolvimento de cada modelagem é explicitado e resultados de simulação são validados através do uso do RTDS (Real Time Digital Simulator) assumindo injeções de correntes harmônicas e a análise da linha no domínio da frequência.

With the onset of renewable power sources onto the network, such as Photovoltaic power plants contributing to Total Harmonic Distortion (THD) in voltage, a methodology to quantify their contribution to the THD in voltage at the point of common coupling is needed. This paper give an overview of existing theory on the quantification of harmonic emission and in particular the method proposed by the CIGRE/CIREDC4.109 working group. It is concluded that the application of this method by single-point measurements can be improved upon by using synchronized multiple-point measurements. Discrimination to identity the harmonic currents regarded as emission is attempted in the assessment of harmonic emission at a PV plant feeding into a 22 kV distribution network
