Hi Jacky,
I understand from your query that you are trying to measure the 3-phase power transfer between the two area models in your system.
In this case, you can follow the below-mentioned steps to obtain the same.
- Use the "Three-PhaseV-I Measurement" block (available at Simscape / Electrical / Specialized Power Systems / Sensors and Measurements) to measure the instantaneous three-phase voltage current flowing between the two areas.
- Connect the output of 3-phase measured voltage and current to the "Power (3ph, Instantaneous)" block (available at Simscape / Electrical / Specialized Power Systems / Sensors and Measurements) to measure the instantaneous 3-phase active and reactive power flow between the two areas.
- One point to consider is that the "Power (3ph, Instantaneous)" block measures power accurately for a 3-phase balanced harmonic-free system. So if there are harmonics in your system, you need to filter them first.
You can further find more information on the "Three-PhaseV-I Measurement" and "Power (3ph, Instantaneous)" blocks in the following MathWorks Documentation links:
- "Three-PhaseV-I Measurement":https://www.mathworks.com/help/releases/R2022b/sps/powersys/ref/threephasevimeasurement.html
- "Power (3ph, Instantaneous)":https://www.mathworks.com/help/releases/R2022b/sps/powersys/ref/power3phinstantaneous.html
Hope this answers your query.
