provide the sequence of operation (load sequences
for load acquisition and load shedding) in the
design documents.
**************************************************************************
The automatic operating system shall be tested to demonstrate [automatic
starting,] [loading and unloading,] [the response to loss of operating
engine-generator sets,] and paralleling of each engine-generator set. The
loads for this test shall utilize [load banks at the indicated power
factor] [and actual loads to be served], and the loading sequence shall be
the indicated sequence. During all operations load-sharing characteristics
shall be recorded. Perform this test for a minimum of two successive,
successful tests. Data taken shall include the following:
(1.)
Ambient temperature (at 15 minute intervals).
(2.)
Generator output current (before and after load changes).
(3.)
Generator output voltage (before and after load changes).
(4.)
Generator output frequency (before and after load changes).
(5.)
Power division and exchange between generator sets.
(6.)
Real and reactive power on each set.
a.
Initiate loss of the preferred power source and verify the
specified sequence of operation.
b.
Verify resetting of automatic starting and transfer logic.

Automatic Operation Tests for Stand-Alone Operation
**************************************************************************
NOTE: Substitute manual operation and transfer for
automatic operation where automatic operation is not
required by the project. Delete automatic loading
system where not required. The designer will
provide the sequence of operation (load sequences
for load acquisition and load shedding) in the
design documents.
