I have read that reactive power sustains/ supports voltage. What is the reason behind this?
There is almost certainly somewhere where that statement is true.
We need more information on context to answer clearly.
Can you please give us a link, or a book and page number, or attach a file.
Thank you for your answer. I have done a google research and i diden't understand the reasons.I googled "reactive power and voltage control."
Besides this, at my job, when i increase the excitation( the field current ) of the generator's rotor both voltage and reactive power are increased. What is the link between them? Sorry for my english.
The answer is yes. Next week a PF Insights article "AC Power Analysis Part 2" will be published explaining that very question.
Thank you. I will wait
Voltage control in an electrical power system is important for proper operation for electrical power equipment to prevent damage such as overheating of generators and motors, to decrease transmission damages and to maintain the ability of the system to endure and prevent voltage collapse.
Did you read the insights article?
to be more precise (if perhaps too brief and 3 months behind too)
it's because the impedances connecting nodes tends to be more inductive than resistive, see anorlunda's insights article
so by ohm's law
the voltage across them causes current that's reactive.
No , i didn't read these insights article.. ok i will read first. Thanks

Hey @jim hardy Thanks for your reply.. i read Reactive Power Relationship thread. it is really helpful to me.. Again Thanks
