Hi all I have a 5 winding transf
(OP)
Hi all
I have a 5 winding transformer and in the software I am working there is no possibility to model 5 winding transformer. Hence I need a work out such that I can replace the 5 winding transformer with 2 three winding transformers.
The name plate of the transformer is attached as a link. It is a start-Delta-Delta-Delta-Delta winding of ratings 10-2.5-2.5-2.5-2.5, 33/0.315kV/0.315kV/0.315kV/0.315kV winding .
Can anybody suggest me literature or some guidelines to model the transformer with three winding transformer.
Regards

Three winding transformer are more common. Perhaps we can suggest to use their modeling techniques as a reasonable approach to be extended to 5 winding units. Consider use 5-two windings transformer and define the mutual impedance between each winding.

RE: Hi all I have a 5 winding transf
I was thinking of modelling the five winding transformer with two three winding transformer.
In my case the transformer is 10MVA , 33kV star and four nos of 2.5MVA Delta, 0.315kV in secondary. So I thought of replacing this 5 wining with 2 nos of five MVA so I can get
2 x(5MVA/2.5/2.5MVA) however that was not a good solution for me as It would require two input. Hence I thought of replacing with three nos of three winding transformers such that a three winding will feed two three winding hence I will have only one input and 4 output secondary. However I am not sure how I will split the impedances. As Five winding tx will have 10 impedances if required to accurately modelled.
I am not sure about how the vector group have to be considered.
Can I replace 10(Y)-2.5(d)-2.5(d)-2.5(d)-2.5(d), 33/0.315kV/0.315kV/0.315kV/0.315kV winding with 3 three winding TXs as follows such that
Tx1-10MVA/5MVA/5MVA (All star connected)
Tx-2- 5 MVA/2.5MVA/2.5MVA (Star- Delta -Delta)
Tx-3- 5 MVA/2.5MVA/2.5MVA (Star- Delta -Delta)
Tx1 will supply Tx-2 and Tx-3.
This way I get one HV and 4 LV delta connected however I am not sure how can I divide the impedances.
Any thoughts
