So I am trying to understand how a ULTC operates in the Reactive Power Control mode (it adjusts taps to control the reactive power in a line). What equation is governing it's operation, and what variables does it adjust in order to increase/decrease reactive flow?
Is it just the simple reactive power flow equation between two buses:
[ tex ] Q_sending = V_sending V_receiving (\frac{V_sending}{V_receiving} - cos(\delta) [ /tex ]
?
And then the transformer just adjusts the sending (or receiving) end voltage, and this modulates the reactive power flow?
Thanks in advance for any help. I've tried looking up ULTC or OLTC reactive power control, but did not come up with much.
