pierluigi Posted August 7, 2019 Share Posted August 7, 2019 Hi everybody, I have to to run a simulation of a grid connected pv plant consisting of three converter units connected in and out with internal LV/MV transformer each (380V/22000V). Then there is a step up transformer from 22kV to 66kV inside the facility and a 66 kV OHL up to the substation where the POC is located. The OHL is almost 2km longHow can I take into account the losses of the different sections MV and HV?RegardsPierluigi Link to comment Share on other sites More sharing options...

pierluigi Posted August 27, 2019 Author Share Posted August 27, 2019 Outside of PVsyst in excelHi,so this means that PVsyst only is able to give a result as if the POC is before the step-up transformer.To have a realistic production forecast, I should thus calculate the loss in % due to the step up transformer and the OHL and then apply to the PVsyst result.Do you find it correct?RegardsPierluigi Link to comment Share on other sites More sharing options...
dtarin Posted August 27, 2019 Share Posted August 27, 2019 Take your inverter output from PVsyst, apply your losses from there in order to the POI Link to comment Share on other sites More sharing options...
