Hello. How I add a model with U1 at the end as a dyre record? I can't know how to do this.

Hello jconto. I want to integrate a PV system in my network. When i go to choose REGCA model in .dyr file I can not find this. Do you know how I can add the REGCA model in generators models?

Hello, I want to integrate a PV in a network in PSS/E. When I go to choose the generator of the renewable machine in .dyr file, it appears to choose between the following models: WT1G1, WT2G1, WT3G1, WT3G2, WT4G1, WT4G2. I use PSS/E 33 version. What generator should i choose to integrate a PV?

No the swing bus is 1 bus. Yes i replace the bus 13 with a wind generator.

When i replace a generator in IEEE-24 bus with a WT4 wind turbine and i do initilization it appears this problem:

Model IEEEX1 Bus 7 [BUS7 138.00] Machine "1 " : initialized out of limit(s) VR

Model IEEEX1 Bus 16 [BUS16 230.00] Machine "1 " : initialized out of limit(s) VR

Model IEEEX1 Bus 23 [BUS23 230.00] Machine "1 " : initialized out of limit(s) VR

Model IEESGO Bus 7 [BUS7 138.00] Machine "1 " : initialized out of limit(s) PMECH(I) CONTROL WT4E1 AT BUS 13 MACHINE 1 WRONG INITILIZATION: ACTIVE NET CURRENT 1.2663 EXCEEDS MAXIMUM 1.1100

How i can solve this problem? Thank you.

Hello jconto,I have the same problem when I try to open .dyr file of IEEE-24 or IEEE-39. I don't know where I can initialize PSSE to its max bus dimension. Can you help me?

I want to put a WT3 or WT4 model of a wind turbine generator in my system. I want to find the file .dyr for doing this. Can someone share this data?

Thank you Perolofl.

When i click OK is appeared this message https://prnt.sc/13d7vfm. So i think that this is ok.

Thank you Perololf. I don’t know where I can see if a shunt is added at the fault bus after the simulation.

When i put OK, the faulted bus is added in fixed switched. Only this happen.

Hello perolofl. I have the zero and negative sequence data in .sav file. When i choose "Calculate and apply unbalanced bus fault" in the dynamic simulation, R and X do not have values. What am i doing wrong?

I'm confused. How i understand that generators maintain synchronism during and after the fault? When i plot angles i take this result https://prnt.sc/134ydkd.%3C/p%3E (https://prnt.sc/134ydkd.)

Υes but how i can calculate the critical clearing time at this network?

I plotted the speed deviation for all generators and i noticed that they are not following each other when the fault occurs in a generator bus and the network is asynchronous.

The network I use is ieee 14 bus. When I trip a line at fault clearing, there is another line that connects this bus with the rest of the network.

Hello, When I do dynamic simulation in PSS/E to find the critical clearing time I notice from channels plot that if a fault occurs in a bus with generator the network is asynchronous at any time I clear the fault and a line is tripped. On the contrary, when an fault occurs in any other bus, the system is permanently synchronized at any time I clear the fault. So i can not find the critical clearing time. Can someone explain to me why this is happening and what I am doing wrong?

Thank you jconto. However, in the files from your drive there are not values ​​for the negative and zero sequence and so I can not calculate asymmetric errors. Can i use the same values with the positive sequence or is it wrong?

Hello, I want to find the original ieee 14 bus system data for a dynamic simulation. I want it for simulation in pss/e.
