KVAR Effect on Load Sharing

When the load is at maximum, is the power factor correct? By that I mean is the PF lagging?

If so do you mean that when the load is less, the power factor becomes leading?

Fellas, reactive power is power (wattless) power in terms of power factor. As we all know the industry standard is 0.8 lagging. This lagging effect is caused from induction motors (not synchronous). Unity power factor is almost unheard of and we strive to correct the lagging power factor with capacitor banks, and synchronous motors. However, when operating generators in parallel, this is an initial problem to be dealt with through excitation, i.e., generator voltage being equal through control of the exciter field. If not, it can be disasterous! Load sharing using controls such as the Woodward 2101 A or D constantly measures the difference in kw and induces the necessary output to the governor actuator. However, power factor in terms of reactive current between generators are the responsibility of the voltage regulators. There was some contriversy for a number of years as to what the best method was, droop compensation or reactive cross current compensation. Mostly used today (and what I design) is reactive cross current compensation connections between regulators.
