DVR model - Doubt regarding injection transformer

hi,

i have developed a DVR with a neural network controller. the problem i am facing is that the series injection of voltage does not take place. in the controller side i can see that it acts for the fault created. even the VSI output shows voltage output for the fault time. but there is no injection into the line....

am using matlb 7.10.0 at college...

pls help me with this problem...

thank you,

When you post please do not use undefined acronyms like DVR and VSI. Not all experts in NN are familiar with them.

Answer 1

[power system]

dear rufus injection transformer is the problem in your simulink ..you should use step up transformer for injecting voltage..

[power system]

you are using toolbox or coding ? by [e-mail]

[rufus]

i am using tool box...... i've corrected the voltage injection part.... pls can you help me with increasing the output of DVR... this model is giving only 85% correction... pls can you help me

[maulana tommy]

why you dont use simulink?

How do i create an injection transformer in simulink?

[RiniAnn]

series injection transformer block is available in Simulink/Sim power systems.
