MAJID's profile - activity

Win7 psse v33

Unfortunately, in order to protect their product, the constructor haven't given any description report of this model

How to do this? , because i have just one .dyr file that contains dynamics data of the whole system, and for this kind of model especially(SWTVD4), there's no description at parameters table wiche make things more difficult

Hi friends, Have you any information about SWTVD4 model and the related k+21 state. At initialize step Psse returns initial conditions suspect with all generator' SWTVD4 model. Regards

HI friends. need your help I'm in a serious problem, and I'm just a beginner with psse
every time I want to run dynamic simulation the psse stops working and restarts, without returning any message, but sometimes after initializing there is no access to run bottom caused by initial conditions suspect The steps that i follow before simulation are : (please correct me if i missed some things ) 1. CONL ALL 2. 100 0 3. 0 100 4. 1 5. CONG 6. ORDR 7. FACT 8. TYSL ( until number of iterations is 1) I read somewhere people talking about START activity it has any relation with that ?. Thank you in advance

I have same problem every time I try to run dynamic simulation the psse stops working, any idea! Help

Hi friends, i'm working in a transmission power network, for the base case i used QV curves to identify the critical buses in voltage and their reactive requirements , but for some contingency cas (N-1) of lines the solution doesn't converge (blown up ), so i can't use qv curves cause of solutions divergence caused by voltage collapse phenomena (maybe ) . So do you know any tools or method to do,in purpose to solve the problem and to know the optimal Compensator emplacement and requirements. Regards

Thanks bro

Yes, just by double click on y axis , i did it. thanks

For those who don't use python ! , HOW to do it with psse ?

Hi every one, i posed a overload criteria for PV analysis engine, and when the process is finished, i checked the progress report at Output bar to see at which step the engine has stopped, but unfortunately it doesn't give enough information;in my cas it gives only the number of branch out of overload criteria( for my cas 6 branches), the question is there any way to determine this branches names or codes ? thanks in advance

Dear friends, this is along time since I'm trying to display pv curves, and I'm still working. So I will so grateful if you could help. The objective is to determine the maximum power that could be evacuated or dispatched between two zone, this two zone are connected by 400kV lines (2 lines connect all the zones in the network ) and 225kv lines (more than 5), in each zone there's more than 2 plants ( each plant has 2 to 6 generators) This is my questions: How can I resolve this error? Is it possible to do pv analysis between this two zone even if they are connected by many and different types of lines where the structure is meshed for 225kv lines ? How can I chose the dispatch method? Each generator in service in the sink and source subsystem is participating? Is there any other way to achieve this objective without using pv analysis? The increment transfer MW is the sum of whole MW produced in zone source ?
Thanks in advance.

Hi friends, how can you exploit the exported data to plote qv curves with excel? Because with psse just the positive side is displayed !

I need help here 😐

Hi friends, do you know how can I display the negative side of Qv curve ? Thanks in advance

Dear friend @yaya , i've added generator in my sink subsystem ,but A new error replaces the old one it says : unable to increment transfer in the base case

By reducing or increasing loads in the sink subsystem! Any way, I'm going to add generators into sink subsystem if that could resolve this issue

Dear friends, i need your help please. When I run pv analysis i get this error : no participating dispatch busses in study system X. I've read all the related posts, but i still lost. I'm working on a mesh network ! And Maybe pv analysis work just in radial and simple network!?? And could you please explain to me how to use this : The subsystem busses code ?? The transfer dispatch method? Economic dispatch ?
Thanks in advance.

unfortunately,i've checked all the related posts. Have you any ideas about the difference between dispatch methods !

In order to avoid complicate cas ,my subsystem source contain one generator bus and sink one non generator bus ,for mon file i don't think if there is a problem, on .mon file we chose juste voltage range and deviation
