I know that in an "electrical plant" consisting in some generator operating in parallel in droop mode control, the load is shared proportional with their rating. In this case, with generators ratings: 500, 300 and 600 MVA, the shared load for each generator will be around 72% from each rating. This means that the shared load for each generator will be: 357, 214 and respectively 432MVA for the third generator.
Hello.. If we using Auto Synchronizing module such as DSE 8610 , should we still to Apply droop to the AVR and Governor it self? Notes : Dse 8610 Biasing the analog voltage from 0-10 Vdc to the AVR and GOV.. Please advice thanks
Thank you for the comment. The query raised by you is explained in the description. Please check the description. Observation is appreciated. Thank you.
Thank you for the comment. Your observation is appreciated. Frequency to be taken should be 51hz and not 50.1hz. The correction of the scale is mentioned in the description box. Please check the description box.
Maybe someone can help me here i got a 12.7 Detroit series 60 in a semi truck. I been going through ecm tuning it truck made planty of power on dyno. But i still don't know what lsg droop rpm does default settings are 125 droop rpm is their any benefits or draw back's changing this to higher or lower value? Max value is 150
I read somewhere that you can't. They fight each other and eventually one takes all the load, frequency rises drastically causing tripping. I definitely read this somewhere recently

Good.. excellent explanation
Thank you for the comment
Really helpful for my knowledge. I appreciate your contribution

It’s very useful for me

Considering the y scale follow the description box, the droop should 1.96%. Is it true?
Speed droop: (51hz - 50hz)/51hz
Thank you for the comment.
The query raised by you is explained in the description. Please check the description. Observation is appreciated. Thank you.
great explanation
Thank you for the comment
Time @1.01, is the droop speed equation divided by No-load speed or Full load speed?
Thank you for the comment.
% Droop = [(Speed at no load - Speed at full load) /No load speed] x100
Excellent :)
Thank you for the comment
describe very clearly
Thank you for the comment.
From the draw: (50.1-50)/50.1=0.002. So the droop must be 0.2%. Am I right ?

Excellent
Can you run two generators in isochronous modes in parallel?
Thank you
Yes. It is possible

@@johanburger6109 can u send the link to the vedio u found?
Your diagrams are wrong. If you calculate the droop percentage given the values depicted on the graph it is resulting to a 0.2 % and not 2%
It is simply 2% of the frequency. 2% of the 50Hz frequency is 1Hz.
@@ElectroGlobe1 But on the graph of G1 the change of frequency corresponds to 0.1 Hz (from 50.1 Hz under no load ==> 50 Hz under full Load)
@@marsupilamiftw Thank you very much for watching the video, and your precious feedback.
The note about the graph will be put in the description box.
thanks for this
