We increase the excitation level to provide VARs and reduce excitation to absorb them. If your plant load is mostly inductive and you would like to mimic the effect of adding capacitor banks to reduce the reactive current then you increase the excitation current. Be careful though, you can only do this as long as you don't exceed the operating parameters of your generator and/or the plant nominal voltage/current limits.

Time to attend the University of Google, from there you will find many answers to your questions on power factor control. As a bonus here's a short course on synchronous condensers:
