2015-04-25 18:08:24 -0500 | answered a question | how to remove a zone? Hi Jconto, Thank you for your kind response. I have tried all the three steps you ask me to do but problem still happens. I have just posted a question in this website regarding to the problem I met. I hope you can help me to solve the problem I met. The project can be downloaded from the link in the comments in my question. Thank you! You are really an expert and warm-hearted guy! |

2015-04-25 18:01:00 -0500 | asked a question | Why there are big osicilation in my PSS/E Photovoltaic (PV) project dynamic analysis? There is very big oscillation when connecting many PVs to the system and do the dynamic analysis. 1. All the PV generation I set control mode to +,-Q limits based on WPF. And I set the remote bus in dyr file as 0. 2. When no fault applied and more than two PVs are connected to the system, the suspect condition is OK, but the simulation output is not flat as output. 3. When I take all PV units and sub network out, the output is flat. The suspect conditions is OK. 4. When I only connect one PV to the system and do dynamic analysis, the output is flat and suspect conditions is OK. I hope someone can help me. Thank you!! |
2015-04-20 12:54:14 -0500 | answered a question | how to remove a zone? Hi jconto, I see you are really an expert in PSS/E dynamic analysis. May I have your email address? Because I need your help and advice in my PSS/E dynamic analysis involving many PVs. But when I try to do the dynamic analysis using dyr file I built. There are many big oscillations in the voltage. I wonder why.My email address is jingzejia1990@gmail.com I hope you can contact me~~~ |
