English term or phrase:lagging power factor
The power factor may be varied on a generator connected to large system by changing the field current. Increasing field current will cause more lagging reactive KVA to be furnished and decreasing field current will cause less lagging reactive KVA to be furnished (or more leading reactive KVA). Reactive KVA is defined as KVA caused by current flow which is not effective in producing power
As had been noted, increasing steam flow through the turbine will cause an increase in generator load, or decreasing steam flow will cause generator load to decrease. Increasing load by increasing steam flow through the turbine will tend to increase lagging power factors (cause less lag in current) or increase leading power factors.
The power factor (or cos (phi) ) is the angle between the two rotating vectors - current and voltage. Ideally it is 0 deg (cos phi = 1.0). Lagging is when the current vector lags behind the voltage vector, and leading is the opposite.
