Look into the collection "Recent Advances in System Reliability" , Frenkel and Lisniansky

editors, Springer, papers N. 6 and 7. You will see there a method of reliability analysis of

a multistate system. May be it will help in your case.

Thanks Ilya B. but this is a questions for DIgSILENT users of reliability module. If any mameber of Reasearchgate usr it let me know. It is not theoretiacal and model question. I am waiting too long for DIgSILENT support team answer :-(

Dear Nikilovski

Realy I dont know what does it meaning DIgSILENT, but I think you can use the baysian theory perhaps it can help you.

Best regards

Hi! Did you manage to get an answer from DigSilent? I have the same problem. 

Yes I got it. The transmission and distribution network reliability analysis do not support model of generator in state enumeration method. There is a trick You need to put a small line or put busbar with generator reliability  data. In reliability adequacy analysis module DIgSILENT has stochastic model of generator and use Monte Carlo simulation for adequacy analysis.

In order  to check how the whole method works, enter some

imaginatory data for the generator:take one set for very reliable

one (from your experience) and another set for a "bad" generator.

Maybe, the results will not differ much....

We had already try it. It does not work. Anyone can set one generator with lambda and r-repair time or FOR-e it does not work. Only Generator adequacy module support stochastic model of generator and load and use Monte Carlo simulation. reliability analysis for transmission and  distribution network on state enumeration model do not work. :-/

I can't believe that the firm which produced the DigSILENT

is not available for interactions with the users:

Dear Ilya 

I am one of the first  user of DIGSILENT software here  in our country especialy we buy it for reliability analysis (from version13 till now 15.2)  and even 16 version. My Assistant prof was at Gomarinhen and we disscused it. Generator  model in state enumeartion module  do not working. Srete

Sorry,

But you have not choice other than speak to the designers.

They must  be not happy that their product is not working.

Best.

O K, I can send you example if you want ?

So as I have promised. You can see that in reliability analysis using state enumaration method generator has no model. There is no failure rate and repair rate or repair time for generaror  Fig 1. In Generator assessment analysis there is stohastic model of generator with as state as one is needed  and here Monte Carlo simulation is used  Fig.2

Thank you for the answer. The answer from DigSilent wasn't of much help to me. Your answer helped me to solve the problem instead :-)

• I am very  happy  for that fact.  Srete 

I have ask the same question the presenter on DIgSILENT webminar yesterday and in the latest  DIgSILENT 2017 version there were no answer from DIgSILENT presenter :-(

Srete

Dear Srete,

I have the same question. How did you pull in the monte carlo simulation for reliability analysis in Fig 7 of your paper titled" RELIABILITY ASSESSMENT OF DISTRIBUTION NETWORKS USING SEQUENTIAL MONTE CARLO SIMULATION "

Dear Umair

The answer is very easy, At that time it was version 13.1 of DIgSILENT program and generator and each component could be modeled with the Stohactical model.(even Transient rate matrics) As you can see from Fig. 7 we used relaibility module with Monte carlo (not State enumeration model),There were these two options. Now in Relaibility analysis you have only state enumeraion option with full load flow or only conectivity option without load flow (min cut-set model). Now in 15.0 15.1 and 15.2 versions are separate Geneator adequacy assessmenr module (from Reliability analysis module) which has stohastic model of generator and loads curves but transmission network is excluded only transmission losses are included. I realy do not know how is now in 2016 and the latest 2017 versions now since I have not them installed and use.
