Hi,
I have a big solar farm with multiple combiner boxes are connected to a big inverter.
The inverter has a number of combiner boxes that are connected to the same DC (+) bus in the inverter. Each combiner box has 20 strings connected to it.
Let's say I have 10 combiner boxes that are...
Hello All,
I'm trying to provide ground/neutral overcurrent setting for a land based microgrid system (The microgrid is connected to utility via Delta/Wye-grounded transformer and I have a SEL 751 relay for my protection), but I don't have much experience in ground fault protection. Therefore I...
Hi folks,
I have a hybrid marine power system, in which there is a 550kW thruster motor fed via VFD from 1000VDC bus.
My question is that: can I neglect the short circuit current contribution from thruster motor back to DC bus through VFD or not in case of fault on DC bus?
Any help will be...
Hi All,
I'm trying to model a synchronous generator in SKM PTW using synchronous generator datasheet. I need to put saturated reactances values in pu, however the datasheet provides me reactances in percentage values. Does anyone know how to convert % values into pu values?
Here is my values in...
