Voltage Regulation: How to Calculate Reactive Power

[gubretaw]

I a question:

1. How does voltage regulation works? I was told that if we set the value of the capacitor so that it supplies one-half of the reactive power absorbed by the line we will get a perfect voltage regulation. Anyone knows how to come up with the equation?

There are many types of voltage regulator circuits. Here's a link to wikipedia's explanation of voltage regulators:
