Harmonics & Mitigation, Power Factor, Damage from Harmonics and Power Costs

12/03/2016 2:36 AM

Hi Guys

Harmonics & Mitigation, power factor, damage from harmonics and power costs

Yes the title is a mouth full, however I'm not looking for explanations on any of the above mentioned items, only links to white papers, web sites etc, that might explain in simpler terms either all of the above, any combination, the relationship between any of the above, in particular harmonics and power costs.

You all might remember my post of post of last year regarding harmonics and EDM in a submersible motor. Even before last year's post I have been amassing data, white papers and test results, but a new problem has now arisen. Now, I am collating my previously collected data/evidence to present in answer to the latest problem, but I feel there might be newer data that I've missed
The new problems would take far to long to explain and I believe I do have a solution but need evidence to support my solution. So rather than debate them, I would appreciate any additional links you could throw my way, direct me to, to help me to find suitable papers, results and data based on my post title.

Many thanks gentlemen and ladies. All your contributions will be appreciated.

Re: Harmonics & mitigation, power factor, damage from harmonics and power costs

Having worked for battery manufacturing industry for 10 years, I can understand the problems associated with un-wanted harmonics. I have attended many seminars conducted by big wigs like Fluke, etc. Our team instead of trying mitigate Harmonics (>28%) managed harmonics. We had 16MVA load and out of 10MVA load is towards Battery-chargers-cum-regenerative-dischargers. We had 6 transformers. What we have done is 1. Switched over mains from 11KV to 33KV, because harmonics will not step-up to 33KV. 2. Then we distributed load in such way that all harmonics generating loads put on particular transformers. 3. some eqipment we had switched over to 12-pulse circuit. We had 7th and 13th harmonics as major.

I long back, read a blog on this forum by an US bloggers that, he could trap the harmonics and used it to light ships's internal lighting.

What kind of drive system is being used on this motor? What is the voltage supply characteristics and source? A drawing of the system with details regarding all this information might lead to more useful material....

Manufactured by Degatron, Bitrode, Jifan, HBL, etc charger/ discharger rectifiers for traction and stationary batteries and battery manufacturing process. No motors.

In my question here, I am not referring to any drive, unlike my previous post last year when it was a medium voltage VSD with an active front end, but no output filters.

However.. please ignore that.. I am looking for any NEW data that you or anyone else might have, as per the title of my post, or found or know about above and beyond what I've already collated.

Any white papers, any experiments or studies that you may know about, anything at all regarding the effects of harmonics, power factor and wasted power

Thanks!

I got it! "the effects of harmonics, power factor and wasted power" is wasted power you just wrote that one,huh.
