PRODUCT DESCRIPTION
Woodward has launched hardware and software updates to address many CIP requirements; however, complete NERC/CIP compliance involves more than the controls and is dependent on plant infrastructure and procedures. The physical security remains the user’s responsibility.
Benefits:
This section describes the general theory of operation of the two versions of the
SPM-A Synchronizer. Figure 1-1 shows the SPM-A Synchronizer with voltage
matching. Figure 1-2 shows a typical synchronizer system block diagram. Figure
1-3 shows a functional block diagram of the synchronizer.
Synchronizer Inputs
The SPM-A Synchronizer checks the phase angle and frequency of the bus and
an off-line generator which is to be paralleled. The voltage inputs from the bus
and generator are first applied to separate signal conditioner circuits. Each signal
conditioner is a filter which changes the shape of the voltage input signals so
they can be accurately measured. A phase offset potentiometer in the signal
conditioner circuit is adjusted to compensate for phase errors. (This adjustment is
factory set with identical bus and generator inputs. It should be readjusted only
where a phase offset has been caused through the line transformers of the
installation.) The signal conditioners also amplify the bus and generator signals
and apply them to the phase detector.
Operating Modes
A user-installed mode switch (single-pole, four-position) controls the relay driver.
The switch must be wired to synchronizer contacts 10 through 13 (see the plant
wiring drawing). The four positions are OFF, RUN, CHECK, and PERMISSIVE.
When the switch is OFF, the synchronizer is out of operation.
The RUN mode allows normal synchronizer operation and breaker closure
signals. The speed bias circuit continues to operate to maintain synchronization
for one second to allow time for the breaker closure signal. When one second
has elapsed, the lockout circuit activates to disable the synchronizer. The lockout
circuit is reset automatically when the relative phase angle exceeds the window
limit after the generator is disconnected from the bus.
The CHECK mode allows normal synchronizing and voltage matching, but does
not permit a breaker closure signal.
