Frequency scans and resonance mode analysis for resonance problems identification in power networks in presence of harmonic pollution

Abstract: The understanding of harmonics propagation in power systems recently gained interest. In HV networks, the current trend of undergrounding is modifying the network resonance frequencies. In LV distribution systems, the increasing deployment of decentralized generation induces new harmonic pollution, which could interfere with power line communications (PLC). In this analysis, the most important elements of power systems (overhead lines, underground cables, power transformers, linear loads and inverters) are mod… Show more

“…The power quality has deteriorated sharply due to the harmonics of currents, voltages, and powers. They caused additional power losses in electrical networks, false alarms of control systems, reduced service life of electrical equipment, resonant overvoltages and other consequences [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19].…”

“…Cabe ressaltar ainda que a opção por este modelo também foi motivada pelo fato de que normalmente as concessionárias de energia não possuem informações mais detalhadas sobre as cargas dos clientes, sendo mais comum a disponibilidade no banco de dados dos valores de potência ativa e reativa das cargas. Verifica-se também a aplicação deste modelo de carga em distintos estudos harmônicos recentes, bem como as discussões correlatas sobre possíveis impactos do modelo utilizado nos referidos estudos (BARAKOU et al 2016;EGGENSCHWILER et al 2017; VIEIRA et al 2018; AMINI, JALILIAN, BEHBAHANI, 2019).…”
