AlvaroRuiz Posted November 21, 2023 Posted November 21, 2023 Buenas tardes, Cuándo trato de realizar una comparativa de producción a la salida de sistema con dos configuraciones, obtenga las siguientes tablas. Inversor central FS4200K a 4200 MVA Inversor de 330MVA No acabo de entender como la entrega de potencia en el caso del inversor central sea tan en una fase tan final y como la del inversor String tiene una tendencia mas progresiva si bien el orden de magnitud por tamaño del inversor es completamente diferente, ¿alguien me ¿Puede explicar esta duda? Muchas gracias de antemano.
Michele Oliosi Posted November 23, 2023 Posted November 23, 2023 The difference is related to clipping here. In the first variant, you have some grid limitation or inverter clipping, which leads to power peaks being all concentrated to the 12175-12200 kW bin.
AlvaroRuiz Posted November 23, 2023 Author Posted November 23, 2023 Good afternoon again Michele, thank you for your prompt response. Is this inverter clipping a parameter reflected in the .OND of the inverter or is it a modifiable element under some type of internal PVSyst standard? If it were an internal parameter and you would like to know where it can be modified. Thank you very much again.
Michele Oliosi Posted November 23, 2023 Posted November 23, 2023 Each inverter has a nominal maximum power, which will determine the clipping level. This is defined in the OND, but of course you can also modify and save a new OND file.
