Thank you so much. It succeeded. I have PSSE Ver. 33.4 The options available were checking Scan for generators exceeding angle threshold I selected Angle Threshold 180 & MBASE threshold. So if needed now to trip by under frequency? I have to add ’FRQDCAT’ to my DYR file or other solution?

Hello,

What is the tool in PSSE which trips the generator in case the generator is subjected to a rotor angle instability? How to implement it?

Thanks in advance for all of you.

I get the following message when trying to initialize the model and sure I get INITIAL CONDITIONS SUSPECT: Out of file data--switch to terminal input mode

The message is written just under the Swing Bus summary

What is the mean of this message and how I can solve it?

Hello

I am beginner in PSSE. I need a Python code to draw QV curves for base case in addition to contingency cases for a certain bus number or group of buses and export the results (Figures) or even tabulated results to Excel. I am using PSSE Ver 33.4

With many thanks.

I am beginner in PSSE. Could you please explain how can I use this code?

Simple question.. How to add a comment or a message that appears when opening the PSSE model for example: Network Year 2025 - Peak Scenario

This message appears just after the below part: SIEMENS POWER TECHNOLOGIES INTERNATIONAL

  50000 BUS POWER SYSTEM SIMULATOR--PSS(R)E-33.4.0

Thank you so much for your valuable answer.

Could you please advise generic dynamic models for Wind Farms, one with 100MW and another with 30MW output power? Also generic models for PV Plants with 40MW and 15MW Peak? These renewable power plants are not sharing reactive power (Q) with the network.

Many thanks in advance

Thank you so much @abdul for your valuable answer.

Yes I opened it in PSSE

Hello,

I have the parameters of a generator model named GENTPJU, when I tried to input the model and its parameters in DYR file, I could not find this model among the list of generator models however it is present in the PSSE 33.4 Model Library PDF file. What I have to do?

Thanks

In old versions of PSSE, I believe before V.35, there is no control from the software on the machine capability parameters.

Thank you so much

In the Generator Dynamic Model which value of Xd, Xq, Xd', Xq' ...etc. should be used and entered to the model, the saturated or unsaturated value? Thanks

Technical Question:

During performing stability analysis on network with synchronous generators, we carry-out rotor angle stability by simulating a fault on a busbar in proximity to a power plant, trip a line and clear the fault after certain time then we plot the power angle versus time to see if the generator will maintain synchronism or not. What is the case concerning PV or wind plants - what is the procedures for checking stability and what values or parameters we have to monitor. I need to understand the dynamic stability for the renewables. Thank you in advance.

Thank you so much

Another question, what is the criteria according to which you assumed X2-3 equal to 0.3. It should be greater or less than X1-2 & X3-1 ? Thanks
