I am working on the simulation of a Solid State Transformer.It has three modules- the PWM rectifier, the Dual Active Bridge Converter and the Inverter.The modules work well individually but the input current gets distorted with the whole system.Why??

When I am synchronising the PWM Rectifier with the Dual Active Bridge Converter and the Inverter, the current becomes highly distorted. However, the output current and voltage as well as the intermediate stage voltages are perfect as per my design. I have tried several PWM techniques- the abc-dq-abc transform technique, the Direct Power Control technique. However every time it is the input current which gets distorted.

please can you send me the model of solid state transformer ? . because i need it in my graduation project in freedm system and i want to make a model of solid state transformer . i searched on the internet but i didnot get any thing . thank you

[Komal Autkar]

if you have completed your project and designed model of Solid State Transformer,then can you help me with the simulink model???

[Afroz Shaik]

sir

I am also doing project regarding solid state transformer but I don't know how to design PI controller so please help me with simulink model

Answer 1

[Taimur Zaman]

Dear Partha Sarthy, As per my knowledge, your input current is distorting because that you are using very high frequency transformer. Since due to very high switching frequency, the energy residues in the transformer winding, and so a huge current start flowing which means simply shorted. You need to design a good series inductor for your dual active bridge, so that during switching, the energy transfers from transformers to inductor and ZVS phenomeno occur.

Hi, could you please share, how to model the High frequency transformer in Simulink.

Answer 3

[Komal Autkar]

I am working on MATLAB/simulink model of Solid State Transformer interfaced Wind Energy Conversion System as my post graduate dissertation work. Can anyone send me the simulation model of solid state transformer?

[Partha Sarthy]

Have you been able to simulate the SST yet?

[Komal Autkar]

Yes. I have simulated SST but not getting exact results. Output waveform is quite distorted with high THD.

[Komal Autkar]

If possible, can you help me to get the proper solution?

[Partha Sarthy]

Hi Komal. It's been some time I have been in touch with the specifics of the project. However, I can surely be of some help if I give a try. Can we sync offline as I rarely open this MATLAB website nowadays?

[Komal Autkar]

Yes..Can you share an email id? sothat I can contact you.

Solid-state transformer (3PN2520B), also known as power electronic transformer, is a combination of power electronic conversion technology and high-frequency power conversion technology based on the principle of electromagnetic induction, to achieve the transformation of electrical energy Stationary electrical equipment. Compared with conventional transformers, EPT has many advantages, and its outstanding feature is that it can achieve flexible control of primary current, secondary voltage, and power. The application of EPT to power systems will improve power quality, system stability, flexible transmission methods, and real-time control of power flows in the power market. At present, SST is used in the field of new energy intelligent microgrids. In the traditional power grid, it is mainly used to solve the voltage disturbance problem of the distribution network.
