1. Harmonics and KVAr: is there any relation?
2. KVAr producing because of generation or depends on various load?
3. Generation side if KVAr increases winding will damage?
In my experience existing system.
DG Rated KW - 3500 QTY - 2 - Parallel operation.
We have 5 quay cranes on load side connected with common bus. Normally our erratic load variation each engine 300 to 2000 KW depends on the operation. During this period KVAr variation DG to DG we got more differences, like one engine 300 KVAr and other -2500 KVAr simultaneously P.F. also. We have only option to adjust the Excitation field. Now adjustment also crossed the limits. Is there any other option to control this unbalance. Please give me the clarification about KVAr compensation details.
Note:
1. At present we touched exitation field Manual pot and AVR.
2. Load type inductive (AC and DC motors)
If any manual is available please send it to this mail ID: electwar @ gmail. com
