How To Calculate Active Power Transfer
From Generating Station to Receiving Station

Find the Active Power Transfer

Given sending voltage, Vs = 500 kV ; sending voltage phase angle theta, θs = 30°

receiving voltage, Vr = 525 kV; receiving voltage phase angle theta, θr = 20° Transmission line series reactance = 150 Ω



1 kV = 1000 V
No need to do conversion. Answer is in MW (MegaWatts)

MW
=
Vs * Vr *
sin ( θs - θr )

Ω




Can you think where else you can apply this computational knowledge you just learn today to improve a design, automate a manufacturing process, or to solve known problem in operation, manufacturing, installation, construction, or troubleshooting? You can add your own existing problem on the list that you wish to solve. These questions are example of critical , analytical, problem-solving and creative thinking that we need to teach our students to prepare them to work together with deep learning, machine learning, and artificial intelligence that are not yet able to do what our human brain can do easily.

If you subscribe to invbat.com you can create your own personal calculator website that will help you to work in a fast moving digital workplace powered by machine learning, deep learning, and artificial intelligence. You can solve similar problem in less than a minute as you can see in above example. For explanation of theory, your teacher, tutor, instructor or professor can help you better because they have a lot of teaching experience about the subject. Also don't forget to search using Google, Bing, Yahoo, Safari, Amazon Silk, and DuckDuckGo search engine to name a few to learn more. Once you acquired enough knowledge, you can go back to INVBAT.COM to speed up your computational thinking.
