Improve the power factor in the 110KV section by over-compensating in the 10KV section!
Thread Content
Dear teachers, I would like to inquire about using under-voltage (10KV level) over-compensation to improve the power factor at the high-voltage level (110KV level)! Is this advisable? What is the impact on low voltage (10KV range)? Thank you!
I have no experience working with high voltages of 35 KV or higher, but I personally believe it’s not advisable; normal compensation should take place within a single power grid
Excessive compensation is not necessary; if there is only one or two 110 kV feeders, a power factor of over 0.9 for the 10 kV system is sufficient to meet the requirements of the 110 kV system, but compensation is still required at the low-voltage level as well.
It's better to use automatic compensation, and it's good to divide it into two or three groups. Set the power factor at any time according to actual conditions
