Per-unit system calculations - Tutorial 1.part 1
HTML-код
- Опубликовано: 18 сен 2024
- The per unit system is a method of normalizing and simplifying the representation of electrical quantities in power systems.
This Tutorial shows the process of finding the per unit impedance values of an Electrical Network.
Doing a per unit system calculation is very important for finding your short circuit current.
It is commonly used in power system analysis and design to express the magnitudes of various electrical parameters in a consistent and dimensionless manner. The per unit system is particularly useful for comparing and analyzing different components within a power system without being concerned about the specific voltage or current levels.
All Electrical components on a network can be represented with an impedance value in per unit form that is the percentage form, this help a great deal to determine the value of the short circuit current.
Explore per-unit system calculations in electrical engineering with this comprehensive tutorial. Tailored for students, engineers, and professionals, this video covers the fundamentals of per-unit systems, including the importance of standardizing electrical quantities and the principles behind per-unit calculations.
Learn how to convert electrical values to per-unit equivalents, understand the formulae for impedance, voltage, and current transformations, and explore practical applications in power system analysis and design. Mastering per-unit system calculations is essential for ensuring consistency and efficiency in electrical engineering practices.

Careful with hacking peace of software that you have no control over the source code.
Thankyou so much. You are the best man that describes complicated topic give easy to understand. Honestly you're so cool 👍
Thank you for your kind words. I'm it was useful 👍
hi Sir a million thanks for you you deserve a million subscribers and one more time thanks for sharing your precious knowldge
from ALGERIA GOD BLESS YOU SIR
Thank you for the feedback and your kind words. Please help by sharing with your classmates as well.
Fantastic my friend very good. Not too fast. Easy to understand! Thank you!
Glad it helped!
Thank you very much, this helped me understand pu systems
Glad it helped! Please consider subscribing, there will be many tutorials on fault calculations, which is the main purpose of pu system.
Very good information. Thanks
You are welcome.
Stay tuned for more tutorial like this coming up, even more complex fault current calculations.
Hi, I like your lecture. Thanks
So nice of you, thank you for subscribing, I hope you also gave a thumbs up.👍
Hello, for the old and new values for transformer 2, did you accidentally mix them up?
Hi yes on Part 2 of the tutorial, T2 values got mixed up while writing them down, but the values where applied correctly on the formula hence the final answer was correct. I hope it was helpfull.
may you please help me with drawing the per unit of a street lighting system where a mini substation is feeding 4 transformers and those transformers are feeding 300 light poles each
You need a feeder System, you already have the sketch on your statement just put it on pen and paper. Each transformer will feed about 75 lights, those light can be reduced to a resistive load with x amount of kVA or MVA depending on how big of the load they are, then you need to know your cables impedances so you can calculate the per unit from it.
Draw it and DM it to me on my Twitter handle @CMTEQ1 will have a look for you.
I hope you have already subscribed.
thank you
Absolute pleasure 🙏, thank you for liking 👍 and subscribing. Stay tuned.
@@CMTEQ i did that without saying that ☺️
I realized that, thank you for the support.
So for transformers, we use any other Vbo(250/800 KV) we want?. For example, you used 250KV instead of 800KV
Hi Vincent, base voltages depends on Zone voltages as per transformers voltage level.
I recomend you watch more vidoes to get a good undertanding.
If you want a session with me you can Join my channel membership I will assist with expalnation and clarifications.
Why do You have a French accent from congo? 😉 Thank you for the tutorial
Tako Mbongo, why is your name meaning money 💰?
Part 2 of this Tutorial will be uploaded tonight. I will solve Zone 2 and Zone 3.
