Voltage regulator circuits: The voltage regulator senses the generator
voltage, compares a recti ed sample of that voltage with a reference
voltage, and supplies the eld current required to maintain the
predetermined ratio between the generator voltage and the reference
voltage. Transformer T1 is the sensing transformer in a standard
single-phase sensing KCR 760 voltage regulator while a KCR 760
voltage regulator designed for three-phase sensing includes two
sensing transformers (T1 and T3). The sensing circuitry also includes a
transformer (T2) and potentiometer (R4). Transformer T2, potentiometer
R4, and an external current transformer provide means of attaining
reactive kVA load sharing during parallel generator operation. The
parallel operation components do not affect voltage regulator operation
when the generator is operated singly.
On regulators equipped with underfrequency limit (UFL) or V/Hz option,
this circuitry interacts with the regulator sensing and error detector in a
manner that decreases voltage during underspeed operation. A solid-state
ashing circuit operates each time the generator is started. The ashing
circuit de-energizes when generator voltage has built up to about 70%
of rated voltage output. Most of the circuits are contained on a printed
circuit board. Parts that are individually mounted on the regulator
case are the sensing transformer(s), parallel operation transformer T2,
choke L1, nominal voltage range set adjust R2, stability adjustment R6,
capacitors C32, C33, & C34, parallel voltage droop potentiometer R4,
the power stage, and a fuse. External voltage adjust rheostat VAR is
provided for installation on a control panel.
Sensing circuit during single generator operation: The voltage sensing
transformer(s) provides a voltage proportional to the generator voltage
output. This voltage is fed across the primary of T2 to a full-wave
recti er comprised of silicon diodes D3, D4, D17, D18, D23, and D24. The recti ed voltage is ltered by resistor R3, choke L1, and capacitor
Cl. The dc signal from the lter is applied to the error detector and the
underfrequency limit.
Shorting the secondary parallel operation transformer T2, either by
using the jumper bar across CT and CT1, or turning R4 to its full
counterclockwise position or setting the UNIT/PARALLEL switch to
UNIT, eliminates the effect of T2 during single generator operation.Sensing circuit during parallel generator operation in reactive
voltage droop compensation mode: Generators interconnected for
reactive voltage droop compensation will proportionally share inductive
reactive loads during parallel operation by a decrease in generator
system voltage. This method of kVAR load sharing is described in the
paragraphs that follow.
The sensing transformer(s) provides a voltage proportional to the
sensing voltage. A current transformer (CT) installed in line two of
the generator develops a signal that is proportional in amplitude and
phase to the line current. This signal develops a voltage across the
slide-wire parallel voltage droop adjust potentiometer R4. The setting
R4 determines how much of this voltage is applied to the primary
transformer T2.
