السلام عليكم ورحمه الله وبركاته....
وبعد...
لا احب ان اطيل عليكم
وادخل في صلب الموضوع
فعلا هنالك شي لم استطع فهمه بكل وضوح.. او بمعنى اخر ان فهمته اليوم وقرأت الموضوع في مكان ما احس بانني بعدي كل البعد عن الالمام به.!!!!!
سؤالي او موضوعي ساتانوله باللغه الانجليزية اسهل واسرع:
Lagging and leading power factor ?? !!!!
Let’s first define that:
When we say lag or lead we always refers to the current (lag/lead) voltage.
So, if the load has a lagging power factor it means its S = P + jQ
And if = = = = a leading = = = = = = = = S = P – jQ
Is that correct?
------------------
If syn. Generation says to be lagging or leading what is that in terms of S?
Lag p.f. generation >>>> S = P – jQ
Lead p.f. generation >>>> S= P + jQ
Is that correct?
-----
What is an induction motor supply? Is it only P or what?
----
And is it applicable to have both load and generator working as lagging p.f. or they must be different in p.f.?
------
And if they both operate in lagging or leading p.f. is that will be good for the system or not? And which is better?
---
It is really confusing
فعلا الموضوع محير وملخبط. يمكن لاني اربط بين اشياء غير صحيحه بالاصل ويمكن لا ..... ارجو التوضيح ممن لديه المعلومة الدقيقة جدا
ومشكورين وماقصرتو
