Thank you so much for your explanation. I am using PSCAD. My question is, in the steps you mentioned after "Inverse Clarke Transformation: Convert the two-phase stationary reference frame coordinates (αα and ββ) back to the three-phase reference frame (Vref_abc).", the three phase reference...
Hi everyone,
I want to simulate a three phase grid connected inverter with SVPWM. My question is, how can I find the magnitude of carrier to compare with reference voltage for generating pulse switches. I attached the reference voltage with random carrier magnitude, but I don't know how to...
Hi Everyone,
I have simulated the system of the attached photo. According to the photo, I am controlling the line to line voltage and phase current of the inverter side of the system. The controlled voltages and currents are in the same phase, but the voltage and current at the grid side (PCC)...
7th harmonic is just an example to find the thevenin model for this harmonic. No, I am not following the mentioned method. My system and controller is same as the attached photo in my previous reply.
As I am controling the inverter side voltage and current, these voltage and current after passing through transformer will have phase shift in the PCC. 7th harmonic is an example to find the thevenin model for this harmonic.
I have two transformer in the system between inverter and the grid. And I am controlling the voltage and current of the inverter side. Therefore, the voltage and current in the grid side are not in phase (because of having two transformers) (please see the attachment).
For finding the Thevenin...
Hello everyone,
I want to model the inverter side of the three phase grid connected inverter with Thevenin equivalent model. But I found the impedance (both resistive and reactive components) negative. Is it correct?? thanks.
